H YANKA BSF-18-4 18 Inch Subwoofer - 2500W MAX Power (1250 RMS) Car Audio Bass Speaker - 2.5" Dual Voice Coil, 4 Ohm Impedance, Aluminum Basket, Paper Cone Subwoofer for Cars

I purchased the BSF 15" 4-ohm subwoofer and am running it on a 2000-watt Taramps amplifier at 4 ohms in a Harmony Audio 15-inch enclosure. For $139, this subwoofer performs far beyond what I expected for the price. I own several vehicles and have experience with a wide range of subwoofer setups. I’ve run Skar EVL series 8s and 10s, a 12" VXF in a large enclosure, SVR model 15s, and multiple NVX 15-inch subwoofers, including the higher-end carbon fiber models. Based on that experience, I can say this sub competes surprisingly well with many mid- to high-tier subwoofers that cost significantly more. The bass is strong, deep, and controlled. It hits hard without crossing into the point where the bass becomes overwhelming or muddy. In terms of sound character, it sits somewhere between the musicality of the Skar SVR 15 and the deeper, more authoritative low-end of the Skar EVL 15. For the price, this is an excellent value and definitely worth considering if you're looking for solid output and good sound quality without spending a lot. Great job on this one.

The sub itself is awesome!!! Great durability and very versatile. I have had mine in everything from infinite baffle to large ported boxes and it performed well in everything. Really loved it infinite baffle. Watch your orders though to make sure you do not get sent a used unit. I got sent a used one on my second order. Did not select used but that what my order was changed to. Arrived blown and unusable. Very upset with who ever did that.

I've been in car audio for almost 30 years and had used many brands and types of subs in many different vehicles and having seen these with a promotional price of $78 my curiosity got the best of me. I have them in 1.25 cubic feet per sub sealed enclosure and even though I'm still in the break-in period, they seem to hit very well. tight punchy bass that peaks at a little higher frequency than other 12s but I believe thats due to the enclosure. Time will tell if they are durable and have longevity but for now I'm impressed

I Bought the sub in Jun 2024 to replace a Kicker CompR out of a Loaded Enclosure where I had Blown out the subwoofer due to shorting both voice Coils, I was recently new to the subwoofer game, since I had just recently bought a New amplifier a AudioControl LC-1.800 from Best Buy I wanted to pair it with a Subwoofer that could handle its Wattage, so I found this in a video review from Wilson Audio and though it might be a good cheap candidate, first couple of months of use and It started to show its first signs of cheap af construction, the surrounding edge where the rubber sticks to the aluminum basket started to separate due to the screws pressing directly into it and it occurred on al 8 holes, had to use a 2 part epoxy to put it back together, fast forward to the last week and I started to smell like burned chemicals coming from my trunk, once I open it, smoked came from the subwoofer enclosure port, good thing I had my toolbox on the car at the time to get the subwoofer driver out of the enclosure and more importantly a fire hazard out of my car, went to the nearest pothole with water that I could find and submerged the motor assembly into it, it was steaming hot, after the water, it didn't even cooled off , after I arrived at home and took a closer inspection, the coil overs where loser in the cavity and appear to have tear out of the Voice coil assembly cylinder where they wound it around, I really wasn't expecting to be a $400 subwoofer but to had perform so cheaply in the construction and the wattage rating didn't even pass my mind at the time i bought it, basket really fells solid and of good quality, I believed Ive has seen it in American Bass Hack line up as well as the driver color but I would Expect different quality from them, Probably just high hopes since at this point I don't believed any sub is made here any more, all chines crap, don't know if the other manufactures might use different adhesives, better quality at least, or their own voice coils assemblies but at least this one product really let me down, for $150 you get what you pay fro the paper cone, spider and basket might be worthy of a 1600W sub but adhesives and voice coil I wouldn't pair it with an 800w Amp, probably a kicker CXA400.1 that I had before could have been perfect with this, I might try to get the cone and voice coil out to se if I can repair it with a voice coil repair kit but even that is spending 80 to 100 bucks to repair a $150 sub, it appears not worthy at all but will keep it just In case I don't have anything to do in a future UPDATE... After the review, a representative from Hiyanka contacted me for a refund or replacement, after 4 days of communication I choose getting a new unit, it did took abit longer to arrived than expected but so far so good nothing bad to report on the new unit, I'll keep you updated if it fails again with same setup

no issues running 1 ohm with one Hyanka 1500w amp ( HYANKA CDP-1500D) that puts out close to 1600w of super clear, Hard Hitting deep bass. I used an osci scope and voltmeter mounted in a Q Power Q Bomb Series 15 Inch Ported enclosure to get the most out of this setup. 4 months of banging without the slightest hint of a problem. 10/10 worth the purchase. this setup replaced 2 Kenwood 12's and a Kenwood 1000w amp for a substantially noticeable upgrade that was cheaper than the original systems cost by a couple hundred dollars. Great BANG for your BUCK.

Speaker had a crackling noise when I first hooked it up and then played for maybe a day then stopped working

These subs dig no BS clear clean bass and can handle plenty of power . 170oz magnet makes then heavy but keeps them cool in hard running times. I put two of these in my kia soul hatchback and they fit perfect. I push them pretty hard and they have held up just fine. Perfect set of subs to liven up your drive to and from anywhere.

Got them wired to 1ohm in a box I built, 7 cuft @ 32hz. I have a Bermans 1800.1 pushing these past there 1000 RMS. Still doing a mild break in but these are really loud lol.

Great and was worth the wait . My bf is happy so I am !

Suena muy bien lo tengo con un Steelpro de 1200 whatts y suena súper bien, patea decente

I am running 2 BSF 12s, 1 amp per sub, 1250 rms @ 1 ohm load each, they take a beating, sub doesn't get hot nor bottom out, bass test playing is 40 hz -5db

I was skeptical, I run a JL JX 1000 1/D For my amp. For the break in period, eas in to it. But it's been 6 months of pounding at 1000 watts at 2 ohms and it's Taking it. No problems.

Looks perfect I can't wait to try it Update!!!! It's been just about a month now that it's been installed and used. It needs a big box. I started off with a less the ideal sealed box and 1000 watts but I quickly noticed the dust cap heating up so I built a ported box put of Mdf and it wasn't great I installed this in my truck so the port noise and motor noise just made it annoying also dust cap was still heating up within one song. Changed out the Amp from an alpine to a kicker running 1200watts rms and it's getting hot still just not for a long time. But I'm on my third box now and it's a large vented box design the sub really gets down with this set up enough to send waves through my windows and roof. Looks to me like the metals going to rip apart shakes the whole body. The excursion of the sub is more then what I have had in the past. And it's response is tight which I didn't expect with a 15 inch. That being said the heat it's generating is still a concern. I know longevity might not happen i can guarantee a short life with the heat that the voice coil puts out. Still a large economy sub that gets low for cheep cheep. Update update Its been what feels like 4 months or more that i have been abusing this sub and it is still going strong. Two things i keep running into is alot of heat being produced in the cone of the sub. My amp is able to match the rms rating of the sub at the proper ohms but when i take it all the way to the max you can quickly smell the coil getting to hot. Even at about half the power shes very warm after a couple songs. But hay its been a long time with it getting hot and its still working awesome. The other major issue that keeps happening over and over is my sub likes to tear itself out of a all the boxes i have used it with. I have tried every type of screw and the screws are not the issue its the mdf itself that tares away each time. I have never had subs pull out of a box before this. But now im lucky to get a week or two of hard hitting bass before it destroys another head mounting board. My box looks all jacked up from constantly repairing it.
