## Description

GRS 6PR-8 6-1/2" polypropylene cone woofers with butyl rubber surrounds are great replacement speakers, but also provide excellent performance in new projects.

Review: Puts us in music dreamland. Beautiful. - This is a replacement subwoofer for my Klipsch Promedia 2.1 speaker system that is connected to my desktop computer. I find that this replacement model is superior to the original Klipsch subwoofer that came with the 3-way system. It is very resonant, and handles all the sub-bass notes with ease. This subwoofer adds a whole new dimension to all of my online music. I'm glad to have it.
Review: Great replacement for old dbx subwoofer - 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.

## Questions & Answers

**Q: what is the outer diameter of the outer most edge of this woofer? please be exact. I'm designing a box.**
A: I know some 6.5" speakers are not 6.5", but these are. Replaced the woofers in my Dayton B652's (which are  6.5" outside diameter) and they went right in.

**Q: Could I use this as a car subwoofer if I put it in a box?**
A: This will give you better bass than most car 6.5's, but it's a replacement woofer for bpokshelf speakers mainly, but home stereo component 6.5's definitely perform better than car ones, some are even 4ohm.

**Q: For those who purchased the speaker as a replacement sub for the Klipsch Promedia, how is the fit and does the amp power the sub as well as the OEM?**
A: They fit perfect except the grill covers do not "push" back into place. Also you have to change the leads on the wiring because the connectors on these speakers are smaller. Really easy to do and they sound great. And yes the amp powers the sub and the OEM.. Super cheap fix, highly recommend.

**Q: What is the frequency of the speaker?**
A: 60-8000Hz

### ⭐⭐⭐⭐ Great speaker for the money.
*by N***E on September 20, 2022*

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.
