GRS 6PR-8 6-1/2" Poly Cone Rubber Surround Woofer
GRS 6PR-8 6-1/2" Poly Cone Rubber Surround Woofer is rated 4.6792 out of 5 by 53.
Rated 5 out of 5 by from OHM CAM 16's are alive again!!I found a pair of Ohm CAM 16's at a yard sale. For $5/pair, I didn't even check the drivers. I just wanted a pair of decent bookshelf speaker for the basement. The 6.5 inch woofer on one had bad rubber, so I looked up the spec's and went looking for a suitable replacement. The GRS 6pr-8 fit the bill on size and, even more, cost. I bought two of the GRS 6pr-8. After a little break in period, I can still tell which side is which (I only replaced one woofer). That is only because the side with the new woofer is slightly brighter than its' 30 year old brother. Now I hate this site because I can't decide if I should just replace the other woofer or BUY BETTER ONES. Arrrgh.

Rated 5 out of 5 by from Can't beat the quality for the price.I did not have a lot of hope for woofers this...let's be honest - cheap. I ordered four of them to rebuild a set of Sony floor speakers that had long since rotted out. They arrived quickly, well packaged and in perfect condition. 10 minutes of swapping speakers around, they're up and running and sound surprisingly tight and clear. They distort at high volume, but it's well beyond comfortable home listening levels. I have to say, A+ for these little woofers, especially at the bargain price of 10 bucks a pop.

Rated 4 out of 5 by from A good value !I bought two of these to replace the woofers in a pair of Baby Advents. They were not a "drop in" replacement, I had to use my Dremmel tool to adjust the cut out...like 5 minutes worth of effort. Other than that pretty easy. Nice tight bass, listening to The Pretenders as I write this and Chrissie Hynde's voice really comes out. A really good speaker for the price and cheaper than re-foaming the originals.

Rated 5 out of 5 by from Good qualityPurchased two of these as a replacement for my Klipsch ProMedia 4.1 system. Although they are not rated for quite as many watts as the originals, the sound quality is near original. I have yet to crank up the volume to really test the power handling capabilities, but satisfied just the same.

Rated 5 out of 5 by from Exactly what I wantedthis woofer works perfectly in my bookshelf speakers. They are the right price, delivered fast, work as intended.

Buying as replacements for a Klipsch ProMedia 4.1, but the connector posts on the speakers look too big for the original cables. Anybody had a problem with this?

Asked by: vince1147
The cable connectors are not all standard, so this is not surprising. You will have to cut them off and solder directly to the woofer or crimp on new connectors.

Would these be a good replacement woofer for Polk Audio RTA 12B speakers?  2-8" mid woofers,  12" passive radiator. 

Asked by: jpsyoda
I incorrectly stated 8" woofers,  when I meant 6.5" woofers in my above question. Originals are treated paper.  How would sound be affected switching to poly cones?

is the GRS 6PR-8 6.5 inch woofer a good choice as a replacement for the woofers found on the Pinnacle PN7+ 2-way ported loudspeaker? My original woofers appear to have poly cones but the rubber surround deteriorated after 15 years.
