Good Value for Money, But With Stands Becomes Great
Using these on my desktop in my home office / hobbyist DAW. Currently running a Schiit Mjolnir 2 straight to to the LSR305 pair over balanced / XLR connection. All trim settings are currently set to flat. Speakers are currently sitting on Iso Acoustics stands, which make a huge improvement in sound. My listening position is about 3 feet / 1 meter from the speakers -- true nearfield. Previous speakers were Dynaudio Audience 42, which were purchased about 10 years ago for about $850 a pair. There are a few things the Dynaudios are better at (treble is a little smoother, midrange a little lusher, overall max volume a tad higher, box a tad smaller and more solid, better fit and finish), but overall the JBL LSR305s are better at pretty much everything else (low frequency extension, dynamic punch, quickness, decay, dispersion, more detailed and revealing) and have replaced the EISA award-winning Audience 42 in my desktop system. The JBLs are much closer to the speed and dynamics of the Martin Logan electrostatics in my main living room rig. Overall, the JBL LSR305 pair beats the Dynaudio Audience 42s convincingly on rock, disco, electronica, dance, and pop. No contest at all. For acoustic, classical, and jazz, it's more of stalemate, with the Dyns being darker, lusher, and smoother and the JBLs being more dynamic (both micro- and macro-) and more 'live' sounding; it's hard to say which I prefer for these genres. Tube-rolling the Mjolnir 2 may add a touch of lushness back. Also, the JBLs are more revealing of lossy and dynamic compression artifacts in MP3s, whereas the Dynaudios were more forgiving. Some songs that were borderline on the Dyns have become noticeably inferior on the JBLs. Not more fatiguing...just noticeably more 'meh'. As for the stands: adding the Iso Acoustics stands is amazing upgrade, especially for the price. Cabinet resonances go down, bass gets tighter, imaging improves immensely. But boundary reflections go down, so you have have to reposition / re-EQ to get tonality back where you want it. However, stands are essential to get the most if you're going to use it on a desktop. Little nits that still need work: 1. The top-most octave has more air than I'm used to. I have to decide if I like this, or if I want to dial it back either via the trim controls or other EQ. 2. Imaging -- the center-fill and phantom center is really really good, the best I've heard on a desktop. However, I haven't got the soundstage beyond the boundaries of the left and right speakers yet. However, this could be a result of positioning / placement, how close I sit, etc. Will need to fiddle around a little more. 3. The box could be a bit deader. Just to be clear, I don't hear it audibly resonating, buzzing, or otherwise making noise. But I can tell, compared to the best mini monitors I've heard or owned, it's a bit more acoustically live which means the magical sensation of 'the boxes disappearing' isn't happening 100%. More like 70%. (For the record, the best box speaker disappearing act I've heard was the original NHT Super Zero, but those little guys only went down to about 80 Hz and the box was teeny tiny, but solid as a brick). We'll see if / how much the Iso Acoustics stands improve this. 4. The hiss: others have reported this, I didn't ever notice this or hear it until I read about it. And, yes, my copies have hiss, too when nothing is playing, but I can only hear it if I put my ears about 3" from the drivers. It's not otherwise noticeable. 5. Subwoofer or not? I've heard the matching 10" LSR310s subwoofer integrated with the LSR305 at a local Guitar Center it's a great pairing for the money for music and for nearfield listening. Do I need it? No. In my ~10' x 10' home office / hobby mixing studio, the 305s put out a musically satisfying amount of bass. Kick drums are wicked fast and dynamic, electric bass is tight and groovy. For mixing, it's great, as the 43 Hz extension covers the lowest note on a bass guitar. What's missing is the last 5% of visceral impact...feeling it in my body...that 5" drivers just can't do. But with bass, less is often more and there is a fine line where more bass just turns into more problems. I've told myself I'll live with these guys for at least a month, getting them more broken in, before I make a decision about adding a subwoofer. I paid ~$250 for my pair. Sometimes you can get it even cheaper. This is an *astounding* value. The fact that it can go toe-to-toe in a near field setting with (albeit a bit vintage) Dynaudios that cost almost 4x the price is an impressive testament to JBLs engineering of these monitors. I'm tempted to get a 2nd pair and hook it up to an Airport Express for easy Airplay streaming in other rooms of my house. If I ever had to move to an apartment, condo or other setting where I could no longer have my beloved Martin Logan electrostats, I could be pretty damn happy long term with a pair of JBL LSR305 and a great set of headphones.

Very good for the price: flat, neutral & professional
These are studio monitors. My review will talk about what they do, what they don't do, who should buy them, and the value. I'll mention a few small issues. So what are studio monitors? Basically, if you record or mix down your own music, you need a special pair of speakers to check your mix. You can't do that on headphones--your mix--the way the different tracks of music sound together--won't resolve spatially (there's no real space with headphones). So this special product was designed to address this issue, as well as provide a live playback in the studio, and so on. Studio monitors do not have an exact definition, and there are different kinds. If you go into a music studio, the monitors are usually set up wrong, anyway. And so it goes. These tend towards what I would call "near field" which means, well, you sit near them. Not really near, but near. High frequencies lose energy over distance, so if you sit too far away they will sound dull. How are they different from a pair of stereo speakers in a hifi system? Well, they are designed in most cases to be flat and neutral, and not impart an attractive EQ, color or bias to the sound. So as far as speakers go, they sound, well, flat and colorless. And that's good for checking your mixes, but not so good for easy listening. Ideally, they should be revealing and mostly unforgiving. You want the truth, just like the ad says. Also, since these are not shielded (more on this later) they are a dud for computer speakers. And, they are for a solo listener. You have to be in the focus point, they focus like a good camera lens--that makes them special, but also a specialty item. So, so far, they from my description they sound like the box they came in. But in fact, they are great. Because when set up properly, you--the listener--and the speakers form the three points of a triangle. And after a few experiments (depending on your room acoustic), when they are set up right, the stereo image snaps into focus, and you can use them exactly they way they should be used--to check a mix. Any little problem in the mix is revealed, and you can quickly find the best mix (assuming you know how to mix). Note that in this triangle, the speakers angle towards the listener, at around 30 degrees. If you move a foot to the right or left, the image snaps out of focus. So basically, if you are looking for studio monitors for mixing on a budget, look no further. These do the job and do it well. They do it better. There are a few minor issues, again, remembering that these are a bargain. First is that the bass port fires towards the back wall. This is always problematic, depending on the room you are in. Having said that, in the focus position in the triangle the bass is reasonably well controlled. Also, the bass really does hit around say 42-48 Hz--it won't hit the lowest note of a large church organ, but double bass or electric bass, pretty good. Next, there is a resonant frequency in the case. That is, if you tap on the case, it has a note. This is surprising for a JBL design, and I guess this in one area where they cut corners. You could open up the case and apply some damping material, but then you risk the warranty and you might make it worse. If I find an easy mod or see one I'll try to post it. Resonant nodes are a common problem in audio, and this is a present, but minor quibble. Much has been written about the tweeter of this speaker and the diffracting pattern supposedly borrowed from more expensive designs. First of all, almost all speakers make this claim of "porting" expensive design components to lower models. In this case, the high frequencies, according to the hype, are less directional--more evenly dispersed. Well, this is pretty much rubbish, it is a cheap plastic design, and the high frequencies are very directional. But the fact is, that's what you want in a studio monitor--you want to sit in the focus point and hear a very accurate representation of the mix. It's a decent sounding tweeter, but if you want good sounding speakers, get JBL "regular" speakers, not these, or the perennial favorite Bowers & Wilkins. These are studio monitors. Next on the minor annoyances list is the overall shielding and hum rejection. There are two inputs, one for phono jacks and one for XLR cables. Now, you can hook up an RCA or banana plug combo--using adapters--from a stereo and drive these speakers (these are powered speakers, so they work with or without an amp or preamp). But the fact is, they just don't work well. Drive them from a sound card, they just don't do the job, they pick up hum and the sound is a bit off. But drive them from, say, an RME interface, or anything with decent balanced XLRs (say a mid range Focusrite, or, my fave, Grace audio), flip the switch from "consumer" to "professional" input level (they are "consumer" by default, at least on my set) and be prepared to be surprised, they do pretty well. The noise goes away. They are also susceptible to hum from dimmers, or electromagnetic hum. The tweeter is just a little bit less bright than flat--that is, there is almost a hint of ribbon in the sound. Not a bad thing, but don't set your mix too bright to compensate. Lastly, there is a very slight color to the sound, a hint of dark chocolate, sometimes edging ever so slightly towards murk. No biggie, but a slight coloration. As another reviewer perspicaciously noted, the coloration is similar to the Audio Technica ATHM50 headphones, so they make a complimentary pair. Compared to my Sennheiser HD600s, they are slightly darker. JBL claims the speakers are "pre" broken in, mine settled in and sounded noticeably different after about twenty hours, so don't mix anything serious until they have moved some air, IMHO. Again, these are some problems, but if set up right with the right cables, you are in business. And so, recommended. And better than anything in the price range. Who are they for: the budget home recording studio Not for: not for home stereo, computer speakers, multiple listeners Other notes: You will need XLR cables, and longer power cords than the ones supplied. There's no protective grill. The speakers have a very wide range for such a small box. Since there is no shielding, they are not too heavy--save the boxes for transport owing to the exposed cones. Do not forget to follow the setup pattern indicated in the obtuse instructions--if they aren't angled in (a very common setup mistake), the highs will be seriously skewed. There's a minimalist EQ switch on the back, I recommend you don't use this. Have fun, and happy mixing.

perfect for even the most frugal music enthusiasts
Most musicians know that when working in a music studio, the quality of the equipment being used can directly influence the quality of the sounds in the finished product. Because of this, producers agree that the studio speakers need to accurately depict the full range of frequencies in a song. That is one of the reasons I decided to purchase a pair JBL LSR305’s two years ago. In addition to its surprisingly flat frequency spectrum, the LSR305 offers professional quality at a consumer price; perfect for even the most frugal music enthusiasts. Finally, their size dimensions allow the LSR’s to fit anywhere from a small bedroom to a full recording studio. Frequency Response The first thing I noticed after testing the LSR305’s was the incredible sound quality they produced. As pictured in the frequency response graph below, the LSR305’s emit an incredibly balanced sound ensuring certain pitches do not stand out. Having a balanced spectrum is arguably the most sought after feature for musicians shopping for new monitors because they will portray the music almost exactly as it was initially recorded. As the volume is increased, many listeners can expect some sound distortion, even from higher end monitors. Fortunately, that is not the case for the LSR305’s. Listening at the near-maximum levels provides the same quality as lower volumes with no noticeable signs of distortion. Because of this, these monitors are not only perfect for aspiring musicians, but are also great for events and parties. Even though the quality of these monitors is on par with other professional products, it may become evident to some users that the LSR305’s sacrifice a small amount of volume for their sound quality. However, this minor setback stems from the necessity of a distortion-free sound rendering the lower volume limit a circumstantial obstacle. Pricing When putting together a home studio, having a budget is essential for picking the products that work best for you. Expenses for necessary equipment can rack up quickly so it is important that the products being purchased a good value to the consumer. The JBL LSR305’s are no exception as they provide professional quality at a consumer price. At only $300 for the pair, the LSR305’s are one of the most inexpensive 5 inch monitors on the market right now. Because of their price, they make a great addition to even the most pennywise musician’s recording studio. Size & Dimensions When designing the LSR305’s, it is clear that the engineers at JBL did not waste any space for the final product. Unlike the competing Pioneer Built5 monitors, the JBL chose to use a taller, skinnier shape for the LSR305’s. As a result, these monitors are able to fit more comfortably on a variety of shelves, stands, and entertainment centers without sacrificing resting stability. Weighing in at just over 10 pounds, the LSR305’s are also quite a bit lighter than the Built5’s (14.33lbs). As a result, musicians on the go will find ease in transporting these between locations. Conclusion Once again, JBL has created another practical piece of equipment that continues to satisfy musicians and enthusiasts alike. From its pristine sound quality to its ergonomic design, the LSR305 studio monitors are an ideal fit for anyone that wants to improve their listening experience in the studio, living room, and everywhere in between. I highly recommend this product to people who want to get the most out of the music they create or idolize without breaking the bank.

Great accessory for my SW receiver!
I bought my LSR305 to use with the Line/Record outputs of my SW receivers - specifically, my Lowe HF-225 with it's AM-Synchronous detector and available 10 kHz BW. I had settled on Infinity P143 small bookshelf speakers to use with my SW broadcast listening receivers, including the HF-225, and like them - they just cannot produce enough Sound Pressure Level (SPL), actually the HF-225/P143 combo tops out less than 90 db SPL with that radio's whopping Watt or two of available audio power, while the LSR305, with it's 41 Watt/channel bi-amp (The 5" LF and 1" HF driver are driven separately.), can put out nearly a hundred times the SPL power at 108 db. My 66 year old ears do need help, but my wife - and neighbors - wouldn't appreciate that all of the time! Still, when I want something a little louder - I can have it. The crystal clarity is amazing as is the lack of a 'sweet spot' - the sound seemingly comes from that side of the room - not from a small speaker. No background hiss is heard with the volume control at minimum, either. It must be located away from a wall because of it's rear mounted bass port, controls, and input connections. I've grown accustomed to reaching around behind it to adjust the sound level (In a studio, the mixer board would have an adjustable monitor output.). I guess the biggest con I had could have been averted by reading the sheet included - with no grille, care must be exercised in getting the unit out of it's inner box (It's doubly boxed from the factory.). No owner's manual is included, but you can easily download/print one from JBLPro dot com. I am very happy with my Amazon purchase - $150 shipped, including a couple of audio cables. Now I wonder how the 8" versions would sound with a CD player - with a remotely controlled volume control... something else to look for! 12/22/14 update: Nearly two months of everyday use and I am a totally pleased with my LSR-305 connected mainly to the Lowe HF-225 short wave receiver. Fantastic clear-as-a-bell sound on SW powerhouses, like Radio Australia (Which I am listening to now as I type.). Then... I had to do it... play CD's through it. I upgraded my office stereo this past summer with an Onkyo C7030 CD player driving an Onkyo TX-8020 50 wpc stereo receiver and two Infinity Primus P163 bookshelf speakers seated on foam pads in corner bookcases. I was quite happy with my setup - the SW receivers are along the right angle wall to my left with the LSR-305 on a shelf slightly back and above my ears and six feet away - perfect position, if it would play my stereo signal in mono. Then - I recalled the Onkyo's unfiltered subwoofer line output - literally a L+R (mono) signal controlled by the receiver's remote controlled volume control. As the output is muted on Speaker B output, I transferred the P163 speakers to those connections. I ran a long RCA/RCA cable and TRS adapter from the sub's output to the LSR-305's input and turned it's gain up, controlling the volume with the Onkyo receiver's volume control. Wow! I started with more recent fare, but quickly migrated to half century old music - like my recent stereo CD of the 1962 Verve recording Getz/Byrd's "Jazz Samba". I was brought back to my HS days - half a century ago - when I listened to the same album - actually, a mono LP - on my kit-built tube amp and home-made speaker. The JBL was far superior, of course - and there was no needle static from dust & scratches, not to mention flatter and fuller response now. I took a trip into nostalgia-land - then switched to more recent fare, which also sounded great. Now I have a quandary... do I buy another JBL LSR-305 and use them on my stereo or two more - to be dedicated to my stereo and leaving the original with it's intended SW receiver application? I opted for a $10 long cable to more permanently run that sub output to the existing JBL so it can more easily 'share' itself. Maybe I'll consider the LSR-308's for the stereo's use - in the future - post bill-paying! Edit 1/20/16: Black Friday found these monitors at $99, so I ordered another one and connected these to my PC for great sound. The SW table top radios are connected to the Klipsch B-10, KB-15, and Infinity P143 speakers I bought for that purpose. The JBL powered monitors radiate switching power supply hash (interference), which bothered my SW listening - I have them on old books on my desk edge and use it for AMAZON Prime videos and music as well as NETFLIX - great audio quality.

Great For TV Speakers!
I needed to replace our old TV sound system...a Polk Audio 20 watt, 3-piece system, 2 satellites and a 5" Sub {paid $90 for it 15 years ago}. Being a musician, I wanted quality sound and a reliable product, but didn't want an elaborate 5-channel setup. I also didn't want to spend beaucoups of bucks on a boutique Home Theater product with more hype than bang-for-the-buck. (not saying that Bose and the like are bad, just pricey) Powered studio monitors seemed to be a logical choice. Today's audio signals in most broadcasts and DVDs are high-def with plenty of processing and EQ. No need for lots of adjustment or enhancement (some guy already spent a few hours getting the sound right...usually). So, what's the verdict? They sound great! The bass response is not as deep as I'd like, but the bass it DOES have is strong and fills the room nicely. I'd estimate the rolloff begins around 80Hz (they claim it goes down to 43Hz...but I dunno...) I can hear the bass two rooms away at a moderately low volume, but you'll need a sub-woofer if you want to "feel it". The highs are not as harsh as I feared they might be, coming from a horn-like tweeter. Crisp but not too sterile. "Just right" would be the term I'd use to describe them. The two drivers work in tandem perfectly, giving a balanced full range sound. The only concern now is, reliability. JBL is not the company they once were. Their QC and CS (including warranty service) has become haphazard. I've seen some poor quality products from the lower-line of JBL in the recent past. Luckily I usually only buy their upper-line units for my gigging/band needs. Most of that has lasted and performed well. (I've had these for a day, wish me luck...lol) Pros: Great clear sound, plenty of volume, bang-for-buck as good as you'll find. Cons: Cabinet size is rather large (though, probably adds bass response), Deep (>50hz) bass is missing, no grill/cloth to cover the speakers (little fingers can be hazardous). If you get the LSR 308 (big brother to this unit) instead, I'm sure you'll get more deep bass, but they're over twice the price. A good sub would work just as well or better for the money, for my needs... IMHO

New standard in budget studio monitor speakers
I've been rebuilding the recording rig in my apartment, so I decided to try a pair of these JBLs after reading positive reviews about their quality, value, and bang for the buck. Somewhere in audio heaven, James B. Lansing is smiling big time. These little powerhouses live up to their rep--provided you have a quiet low impedance system feeding them. I use a Focusrite Thunderbolt audio interface and balanced wiring throughout; the result is pristine response with impressive volume. They get twice as loud with deeper, truer bass than their closest competitor, the Presonus Eris E5s, no offense to another well-made brand. Well defined bass extension without a noticeable port hump. For hip-hop, scoring or electronic stuff I imagine the affordable matching subwoofer would provide the required extra thunder and boom. Pleasant mids and highs without the overly harsh components that often accompany a horn-loaded tweeter. The detail, imaging and soundstage aren't comparable to a $1000 pair of Dynaudios or ADAMs, so I compensate by double-checking my mixes every once in a while on my trusty Beyerdynamic DT770Pro headphones, which of course offer more definition and detail. Yet the overall eq and balance travel very well between these two sources, I don't have to tweak eq or compression much at all, which means the overall mix accuracy is pretty spot on in the JBLs. I keep comparing these near fields favorably to my long-gone Yamaha NS10s; punchy, open, easy to get a good mix without a lot of fuss. They're not gorgeous. The rear inputs, knobs and switches aren't top quality. JBL has focused on the best possible audio output over slick looks and materials, the right decision for a budget priced speaker. Whether looking for a low priced reference to add to other monitors on your console, as stereo speakers for your laptop or home stereo, I can recommend these versatile speakers without hesitation.

An active monitor steal!
Heard these monitors at a friends place and was blown away. Then lo and behold Amazon has them on sale...$99 per monitor...unbelievable. Immediately bought a pair. I love my Dyns, but for craps sake these JBLs are amazing at a fraction of the Dyns cost. They arrived today and are sounding fantastic in my setup. Just can't believe how low these go and with a 5" midwoofer. That tweeter design isn't hype...it flat out works. Comparing these to my BM5 mkIII monitors....yikes. I'm sorry but at 1/4th the cost (And the Dyns were heavily discounted!) these JBLs are damn impressive....if budget is important look no further than the 305! ** update ** Just bought a second pair last night. Best deal in audio...period. Going to make room for these...slide over Dynaudio! ** update #2 ** I was asked a question regarding any audible hiss coming from these monitors. The answer is "yes" there is a faint hiss emitted from the tweeter. But this does require a bit more detail. If you're sitting say at a 7-12 ft distance from the monitors it's EXTREMELY unlikely you'll be able to detect the hiss. Maybe if you have youthful, perfect tympanic membranes with pristine inner ears you can, but not my 52 yr old ears! Now if you sit close..say 1 ft or closer (ear pressed up to the cabinet) than you will likely detect it. During my listening periods I've found no negative impact to the music, but you'll have to see how you feel about it. This minor issue doesn't surprise me, I mean c'mon these are a JBL design made in China....a corner or two had to be cut somewhere to meet this price point. I think this is one of the few areas where the 305s come up short against my Dynaudio Compact and BM5 monitors....the Dyns have no hiss. The dyns have no gain control so when they're powered they are running at max gain. When I crank up the analog audio control to "max" and place my ear directly over the tweeter I hear nothing at all....I mean maybe, just maybe there's something there but heck it could be my mind is a bit fuzzy. Point is that for the Dyns cost there ought to be zero (or extremely little since most experts claim all active monitors emit some level of hiss even at idle) noise emitted so it's basically what I expected. Anyway, I think the JBLs rock and I still heartily recommend. hey this is a nice review from the perspective of a person (like me) who isn't a music pro, and uses the monitors in ways similar to mine. http://www.wired.com/2014/01/jbl-lsr305-studio-montiors/ ** update #3 ** I think I found a chink in the armor so to speak. When I play FLAC files from my phone I'm able to induce an audible "pop pop" from the woofers. This occurs during track changes and whenever I touch the screen (pause, play, forward, reverse on-screen buttons). It occurs with both XLR and 1/4 " jack inputs. I tested this with the Dynaudio compacts (XLR only) and couldn't make the pop occur. I also tested it with the second pair of 305s that I have and they exhibit the same behavior. It's not intolerable, but it does get your attention. If I play the same music from my mac mini or laptop (using Vox player) there's no such issue. I'm going to run the same test using my Chromecast audio unit and see if it isolates the monitors from the popping.

Perfect Entry-Level Speakers
So I finally got the JBL LSR305's in a few days ago. I've been playing around with them and trying to assess the pros and cons of the monitors and have finally come up with a suitable review. The 305's are the 5-inch version of the 3-Series of JBL studio monitors. The 3-Series also includes the LSR308, the 8-inch version, and the stand alone LSR310S, the stand alone sub. The general idea behind the 3-Series is to give a more than capable studio monitor setup at an affordable price range for the average producer on a budget. When I finally got the package, the studio monitors seemed huge to me. They weighed about 15 lb a piece and are around a foot tall. Looking back on it now, the 305's would fit perfectly into any small to medium sized room. If you wanted the 308's, I'd only really recommend them if you have a large, but acoustically treated room. A lot of my friends say I have a large room, but I consider it medium since it doesn't quite give off a large enough acoustic slap-back for me to feel "lost" in the sound. Both 305's came with a power adapter, instructions, and suitable packaging. I'm actually using the 4 foam pads that came with the monitors to cut out some of the bass resonance, as well as getting the monitors to ear level. When pads are $30 to cover one monitor, you do what you can until you get the money. Setting up the 305's were super easy. Make sure you have an instrument cable (1/4 inch or XLR-to-1/4 inch) for each monitor and an audio interface with at least two outputs before you even think about buying these. They are both individually powered, so make sure you have a power strip as well. When you get them set up and properly EQ'ed by using the (2- dB/0 dB/2+ db) High and Low Trim options on the back, you're ready to rock! Pros: The 305's have an amazing image control waveguide, which was adapted from their master reference monitor. The sweet spot and the stereo imaging of these are INSANE. You can really hear the stereo separate from the centered elements such as kick, bass, snare, vocals and etc. It's hard to even really describe the imaging accurately, but think of an imaginary 3rd speaker right in front of you accounting for the mentioned centered elements. It's super nuts. The frequency curve is super accurate. My mixes translate flawlessly from my bedroom, to the car, to the phone, and etc. These are probably the most accurate within the $300 range. The KRK's seemed to be way over powered bass wise and drowned out the treble in the mix. The Yamaha's weren't bad either, but for my liking they were not flat enough frequency wise. With the extremely accurate representation and the amazing stereo imaging, the JBL's were a no-brainer. Cons: These speakers are borderline perfect. The only real draw back is the lack of lower end sub-response, which were to be expected from the reviews and nothing too surprising from a 5-inch woofer. The lowest register they can audibly hit is around 42Hz, although they can go lower to around 30 or so before losing a lot strength. I've honestly been compensating for a few extra Hz by using the stand alone sub from my last setup and plugging it through the headphone input. This at least gives me a decent understanding of the sub presence in the mix, especially since I can control the sub volume independently to it's not inaccurate. Don't get me wrong, though, these speakers do not lack bass. They push air with the rest of them, they just need a bit of help in the extremely low sub frequencies. My final assessment on these speakers are that they kick solid ass. Great for entry level producers just starting out with their first studio and even great for fresh professionals. I found mine for $112 a speaker, which saved me a ton of money instead of buying the pair for around $275+. Great studio monitors, JBL is my go to.
