GRS 6PF-8 6-1/2" Paper Cone Foam Surround Woofer
GRS 6PF-8 6-1/2" Paper Cone Foam Surround Woofer is rated 4.8 out of 5 by 10.
Rated 5 out of 5 by from Speaker repairThese woofers were an excellent replacement for the original woofers in a pair of Proton speakers which had worn out speaker surround foam. Less expensive than re foam kit, easier to install,and sound great.

Rated 5 out of 5 by from Great ReplacementBought a pair to replace sub par drivers in an old set of Realistic Optimus STS-65s. Much tighter and better low end extension. The cabinets turned out to be perfect size for the sealed parameters of this driver so I sealed the ports and so far they are just getting better as they break in. Great value.

Rated 5 out of 5 by from Great sound at a low priceThese smoke the blown woofers in my Sony 3 way bookshelf speakers.Thanks PE!

Rated 5 out of 5 by from Works as i hoped it would.Tried to pair 2 of these with some 2 inch tweeters. Tweeters didn't survive the install. Long story. But these are put in a small box right in the center under my 82'' tv. Definitely helps out with the vocals. As far as musical ability the bass is a little punchy. I should have aimed for a little lower hz but i hardly do music on my surround sound anyways.

Rated 4 out of 5 by from Replacing old and worn out parts.I bought these to replace the worn out OEM drivers in a set of EPI bookshelf speakers. After researching this particular set, I learned that the Original drivers were a little lacking in performance and other people were going with another driver so I decided to replace instead of refoam/recone. So far, so good. They sound really good, but I haven't had a chance to really crank 'em up. (Looking forward to that.)

Rated 5 out of 5 by from Great replacement car wooferPutting these in a 2000 Chevy Silverado to replace the stock and blown woofers in the front doors. Looked it up on another site saying the originals were 6.75 inch drivers I opted to pair this with a Goldwood GT-302/S tweeter to keep the prices down, but performance up. This pair sounds phenomenal together. The woofers provide a nice overall low end for music. Having used these in a bookshelf speaker application, I knew what they were capable of and what was being looked for.

What's the difference between the PR-8 and PF-8 . . . I'm looking to replace the speakers in my Boston A40's

Asked by: Miltster
The PR-8 uses a poly cone and rubber surround, the PF-8 uses a paper cone and foam surround.

This would be a good choice for a free air application. You can expect 40-50 Hz in the right place.

Is an SPL chart or Impedance chart available?

I would like to use these in a speaker project, but I don't have the equipment to generate these charts myself.
Asked by: Trent
Hi, Trent. When we have detailed specifications, graphs, charts, and the like available, they will be linked under the "Manuals/Resources" heading along the right-hand side of the product page. On this particular driver, we do not have any detailed specifications, unfortunately.
