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.

This is my base speaker in my Jeep.

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

I got two of these GRS 8" woofers in late 2023 to replace the woofers in my 16-year-old PA speakers. The surround material on the old woofers was wearing out and cracking, and I thought the GRS drivers would be a nice upgrade. Unfortunately, they produced less bass than the originals and sounded very flat. I use the PA speakers a few times a year for karaoke parties, so they're definitely not abused or overworked. Fast forward one year, and both GRS woofers are blown with fried voice coils. These are supposedly 200W drivers, but they couldn't handle my little 50W amplifier.

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!

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.

I took on a project to refurbish a pair of vintage 4300 series JBL monitors. Believe it or not, the monitor cabinets had been sitting up in a garage for over 15 years. I wanted to keep the original JBL blue color in theme, and the outside of the cabinets I sanded them and stained a walnut mahogany. Remarkably the tweeters were in perfect condition even after 39 years.However after 39 years of various climent exposure, the woofers were toast.I went on a quest to research the best possible solution for a woofer replacement. I purchased these from Amazon and mounted them inside the cabinets. Although I am an amateur audiophile, the end result literally made me cry. The depth of these woofers and tweeters combined is so remarkable, I heard Kenny G taking breaths in between notes as he blew his sax.my vintage JBL monitors are priceless to me. I wouldn't sell them to Bill Gates if he landed in my backyard in a gold helicopter with cash in hand.
