GRS8PR-8 8" Poly Cone Rubber Surround Woofer

I bought an old-school DOD ICE-T 60 Watt guitar amp from a thrift store for $20 a few years ago. It had old paper cone / foam surround 8" / 8 Ohm speakers that were totally destroyed. But I remembered that these little amps had great specs, effects, sound, etc.These speakers are advertised as home-stereo, box/speaker replacements - but I gave them a try - and they are killer..! I marked and drilled new mounting holes into the amp and the speakers installed and fit perfectly.These 8" 8 Ohm speakers are SO much better technology, sound, durability, and performance than paper/foam old/tech speakers..!!I am Very happy!! Thanks for the well built, affordable speakers!!

I purchased one to replace a blown woofer in a pair of old JBL bookshelf speakers, but I should have done more research beforehand. While the speaker is of quality construction and performs well given enough power, it was not a good match for my application. They are not very sensitive, so even with the bass cranked up to the maximum, at low to medium volumes it barely makes any noise. Once you give it some juice, it sounds good and has strong, punchy bass. For $12 I feel it was worth experimenting, but I will be looking for something that has better sensitivity.

Purchased 2 of these speakers to replace the Woofers on a pair of Yamaha NS-6490 speakers that were giving me some unwanted pops with low bass sounds in movies! At first I was a little skeptic of these polypropylene woofers; they replaced woofers that were marked 6.5 ohm even though the speaker box label has 8 ohm! I thought I made a mistake with these speakers; I got them in, connected them & thought the older ones sounded better, even after performing the AVR auto setup for them, BUT, after several hours of use and a couple of TV shows & movies later I noticed the bass becoming richer & feeling the low frequency more. A couple of days & more hours of use I reset my auto setup on my AVR & even with the movie "UP" in the scene with boulders crashing the "feeling" of the low bass was very good; I could feel the vibration of the falling boulders & I could increase the volume beyond the point the originals would pop & crack! We'll see how they last in a couple of months!using AVR with 90 watts/channel03/31/16update informed by seller that these woofers, as all drivers, have a break-in period of 20 to 40 hours!

Update 2: Fast forward 2 years of light use, and both GRS woofers are blown with fried voice coils. These are supposedly 200W drivers, but they couldn't handle my little 50W amplifier. I only use the PA speakers a few times a year for karaoke parties, so they definitely weren't abused or overworked. Pretty darn disappointing!!!Update 1: The sound quality got somewhat better after a couple hours of use, so I guess they just needed to be broken-in a bit. One star added...Original Review: I got two of these GRS 8" woofers to replace the woofers in some older PA speakers. The surround material on the old woofers was wearing out and cracking, and I thought these GRS drivers would be a decent upgrade. Unfortunately, they produce noticeably less bass than the originals, and they sound flat with very little depth. They'll still work for my needs despite the less-than-stellar sound quality. The PA speakers are used for karaoke at our organization's Holiday parties and Spring picnics, so hopefully they'll last for many years.

This was worth every penny so it was worth the 1400 pennies. It sounds really great probably even better if broke in. It isn't very powerful but again for the price pretty great it is still better than buying other speakers that are 5x the price. It doesn't play full range only mid or sub frequencies it could shake a small house but not mine. But still only $14.

It's difficult to rate a speaker that costs so little. Is it unfair to compare these to speakers costing three times as much? Yes.All I can say is, they work. The surround is stiff and I don't see that changing over time. The sound is very midrange, the bass is audible butit is half of the bass one would desire. These are good for talk radio as they are completley devoid of any boominess. I installed these in ainfinite baffle with fiberglass inside on the back and one side, made by Sony. For the record, I have three sets of four inch speaker enclosures that sound much better than these, five inch low end JBL speakers blow these away. The sound would be good for monitors for use in a live band situation, very midrange and loud.

Update.. 2 months of good testing.. these still rockin… receives my stamp of approval.. great sound, high quality…. Original review: Time will tell… have not had time to full test out.. but for the money, seems to be decent. I ordered 2, one to replace a blown speaker in my vintage techniques speakers. The other one arriving next week, so I don’t have the full effect yet. Far as quality, way better than original… can’t wait to have both

Look and sound good. Worth the money. Used them to replace woofers in 45 year old KLH speakers. While not a perfect physical replacement fit they do the job. 4 holes rather than 8 holes and the gasket is much thicker than what was on the original so the front cover stands off a little. Because the surround is rolled up to allow large excursions it is not practical to cut away the gasket. Not a problem if you are using as an internally mounted speaker. Closed box speakers such as my KLH 32 used a thinner speaker frame and did not require a gasket on the front, just the backside as they mount on the outside of the box.
