GRS 6PR-8 6-1/2" Poly Cone Rubber Surround Woofer

The foam surrounds in my old dbx subwoofer speakers (circa 1990) finally crumbled apart due to age. I didn't realize this until I recently rearranged my audio setup and took the opportunity to open the subwoofer panel and check things out. I had experience in the past with the foam cone surrounds on other speakers crumbling apart as they got older. Sure enough, upon opening the subwoofer panel both woofer surrounds were dried up and cracked. My guess is they had been this way for years and the sound degradation was too subtle to notice. At first, I considered just replacing the foam surrounds using a rebuild kit but I didn't think that the original speakers were of such high quality that this would be worth it. So, I started looking for a durable, 6.5-inch replacement woofer with similar specs to the original equipment.Since the old speakers had minimal markings, I did some research online about how best to select subwoofer speakers. I quickly educated myself about speaker power rating, natural frequency, and Q-factors. There is also good data out there to help you select replacement speakers considering factors such as whether or not your subwoofer is enclosed or ported. After considering various options, I determined that the GRS 6PR-8 was the right replacement since it met the power handling spec, cross-over characteristics, and enclosure design plus they also have a poly-cone and rubber surround. Rubber surrounds are considered to be more resistant to age than foam. Installation was easy and I couldn't be more pleased with this do-it-yourself project. My sound system is like new again. Great product and lots of choices from the vendor, Parts Express.

I bought these to replace my Klipsch promedia 4.1 subwoofer drivers. The pre-existing woofers rotted on the surround. I could have re-foamed them but the removal of the plastic edging was too much of an undertaking for me. I was afraid I would damage the speaker beyond repair. So I looked around and read some reviews on some other 6.5" woofers. These speakers fit the specs and the price point.I had almost forgotten how amazing the Klipsch's sounded! I fell in love all over again! Very clean, tight, crisp bass response. Everything sounded good, from hip hop, to rock. From the digital bass line to the pluck of a bass guitar. And another aspect I really liked was the fact that I didn't have to abuse these speakers to get some sound out of them. These things should be outlawed.... The construction was very solid. The rubber surrounds guaranteed me I wouldn't have to worry about them rotting again ;-)The only negative I could say is that I wasn't able to put the grills back on due to the fact that the originals had a special oversized flange built into them that accommodated the grills. And the polarity wasn't marked.... Not a big deal. Use the battery trick.Overall for bang for the buck they are more than great in my application. They are well built and fantastic sounding. I would absolutely recommend these speakers!

I purchased this speaker to replace the original subwoofer speaker in a Klipsch ProM221 unit. Looking into Klipsch replacement speakers and rebuilt Klipsch speakers, it was looking like I was going to have to spend about $50 - $70. This GRS came up for $20 with a rubber surround. I know the rubber surrounds don't have as much excursion as the foam surrounds that come with the original Klipsch but considering re-foaming the original 14 year old speaker would cost the same as the new GRS, I went with the new GRS.Installation was very easy and the speaker fit perfectly as well. I didn't even have to re-drill new holes.The sound quality is very good. The AMP and speaker unit doesn't seem to have a problem with the speaker and everything seems to be on the up-and-up. As for the bass, it is more than acceptable. I don't get the really low bass with this speaker like I did with the original Klipsch driver, the sound I do get is very nice. Since this is a speaker setup for a PC, this driver works well enough. The music I do listen to is well delivered and sounds nice and full with this driver. When I play my games on the PC they sound terrific. I don't get any rattling or hissing from the driver. I cannot speak to long term performance as I have only had this unit in place for a couple of days, but if anything does happen within the next couple of months, I will re-post. So far however, I am very happy with this product.

Excellent sound, it replaced a worned out Klipse 2.1 HTX 6.5 speaker.

One of the speakers in my shelf unit for my record player. Quit working found this on Amazon. At a great price purchased it and I could not be happier very clear. The bases are very good. Got a heavy duty magnet on it. Fit perfectly into the cabin that already had ten out of ten

Great speaker replacement for Klipsch ProMedia 2.1 THX system original subwoofer speaker. The system was approaching 10 years of age and the original subwoofer speaker cone popped. This replacements fit the hole in the box and lined up with the screw holes perfectly. It was the right size as previous reviews stated. The overall width of the speaker housing wasn't wide enough to securely reinstall the speaker cover though. I used some electrical tape for as temporary quick fix to hold the cover to the sub box. One of the speaker terminal connectors on the original wiring and speaker is wider than the other, and the terminals on this replacement are both the same width. I had to go to the hardware store to buy a box of the correct size terminal connectors and clip the wire with the smaller connector size and crimp the correct size onto it before reconnecting that particular speaker wire to this replacement speaker. The speaker terminals were identified with a "+" and "-" on the speaker I revceieved. It was etched into the metal, but t was a little hard to see. Overall, it wasn't a super easy, straight-up plug-and-play replacement but the results were great and continue to be so.

Speaker is weak.
