GRS 12PR-8 12" Poly Cone Rubber Surround Woofer

I love these woofers!Summary:- Used in Pioneer CS-G303 cabinet (replaced original woofer, but still using original midrange and tweeter) - see photo- A Sony STRDH130 2 Channel Stereo Receiver is being used to drive themI bought these woofers to replace my aging and deteriorating Pioneer ones, which were approaching 30 years old. Not a bad run, but they were showing their age. These GRS (Parts Express) woofers didn't exactly fit in the Pioneer cabinets due to the inner bevel - the cut-out needed to be enlarged about 1/16th of an inch. Once that was set, they fit perfectly.These speakers are used in my garage, so they're purely for casual listening. With that said, I was kind of shocked at just how good they sounded. They have a tighter feel along with a slight bump in the low end compared to the old ones. Using a sample tone album I found on Spotify (search for the album "Audio Test Tones") I was able to get a great response down to 40Hz, but once I got below that it drops off quickly. 30Hz barely registered. Your mileage may vary depending on the enclosure you install these in and the amp you use. I use these speakers only for music, so this is more than good enough. I've listened to these for about 10 hours and they had no issue playing loud for long periods (3 or 4 straight hours).Spending a little money on these woofers I'm hopeful I've extended the lifespan of these old Pioneer speakers for many more years to come. Highly recommended!

This speaker is great! I used it to replace and old Crate PA speaker. It brought the PA back to life. Overall this is not a bad deal at all for the price point. I couldn't be happier. I definitely recommend this to anyone who needs to do a replacement for cheap.

Rocking with the sound, very well made, sounds great....

For a home theater project works great but would not recommend who is looking for lows in theirs

Re-foamed my ~50year-old woofers--I ref-oamed several years ago. The refosm came somewhat undone this year. I jerry-rigged that, soon afterwards purchasing these.The butyl rings for these "young-uns" is better than foam--it's not "invincible," though.As for the "universal" speaker mounting rings and cone here, the 12" enclosure hole-size, and the four Advent holes/screws fit and work superbly.More presence, efficiency, longevity result: Modern tech wins! (Why should that be a surprise?!) A great value, too!No more fooling with paper cones, foam rings, cruudy old debris, difficult "model airplane" glue application, old glue removal, urgency--and, straining at gnats. Move on to other projects and enjoyments....I say "Proceed": Everything about logistics, install, and performance was/is great! (Every new speaker setup requires a little time to "break-in.")

Bought this old stereo console couple years ago(it worked, but I bought it with intentions of converting it to my will, lol) to start my home theater project. Last year, ordered these subs to run in parallel for a 4 ohm impedance. My receiver happens to have a powered sub output using a smaller driver(high end older Sony 6" driver). Not enough lower end from that poor old sub, it works great for mid bass down to around 50hz, still going to use THAT with center channel now to fill front stage a little better. Pre broke these in using a cheap box I've had for years in my truck(used as midbass, seeing 50 watt rms 8 ohms per woofer in my truck off of mid range amplifier, I have a competition woofer already in it, no need to blow them on sub amplifier). They sounded awesome as midbass! Want to buy more of these for my truck, too! Now finally applying these woofers to my home theater sub cabinet. Used cut off wood peices from other projects over the years, so all wood and screws and glue were pretty much free, as I keep tons of glue and fasteners on hand for all my projects. One chamber is sealed, 50% poly filled. Other is ported(22 hz tune), port down firing also with both subsface down to turn entire underside into a 6th and 4th order cabinet. Putting these in 6th and 4th orders allows woofers to hit below resonate frequency, efficiently. And cover alot of bandwidth. This sub WILL hit below 25 Hz in proper tuned enclosure, tested with simple frequency generator app. Cabinet is getting a paint job, most definitely! Lol, its so ugly! Less than 50 bucks to put a huge smile on my face while watching movies, YOU BET! OH, And I still retained the space in top( these old consoles usually have around 5 cubic feet plus,, more than enough space for 2 12 inch drivers)that opens for blankets, wheres my popcorn?

I recently bought some older loud speaker boxes at a garage sale for 20 dollars but the three way wiring was fried out same with the speakers so i waited a few months i started looking on amazon and found everything i needed from goldwood sound as soon as everything arrived i quickly installed all the speakers and wiring needed they are really good speakers and the bass is phenomonal
