Rated 5 out of 5 by from Solid purchaseThese are a great pair of speakers for the price. Just updated my old Cerwin-Vegas and they make an excellent upgrade to the old woofers that were falling apart.

Rated 5 out of 5 by from Great sound at a great price!I have a pair of Kenwood JL955WAV speakers. When I got them, the speakers had the foam rubber completely deteriorated around the cones. It would have cost me more to have those speakers repaired. So, I purchased a pair of new speakers. When I installed them and hooked them up to my stereo system, the sound was mind-blowing. I would highly recommend these speakers to anyone. You cannot beat the sound or the price!

Rated 4 out of 5 by from Fixing up an old friendI purchased these woofers to rebuild a set of KLH cabs that I picked up on the side of the road. There were no drivers in them, and still need a little bit of work, but along with some new mids to go in as well they are turning out well.These woofers sound great, a lot better than the DVC subs I had in them before.

I need to replace a 12" subwoofer in a infinite 3000p speaker. Would this work? If not, what would be a better, price efficient option?

Asked by: easymachtdas
The best option for that speaker would be our Dayton Classic 12" which you can see below.http://www.parts-express.com/dayton-audio-dc300-8-12-classic-woofer--295-320

Ordered 4 of these to replace 4-12's in my "91" Sony 270 watt max speaker box with a tweeter and mid range up top.Pulled  2-12" woofers out of 1st box, realized the bottom 12" woofer was not wired and are no more than a baffle of sort. Wire both in ? or ?

Asked by: Smythe
It sounds like Sony used a single woofer and passive radiator design. In order to wire both together, you would have to make sure your amplifier can handle a 4 ohm load. If it can, Wiring both together will give you smoother bass response but if it cannot handle a 4 ohm load you will have to leave one unhooked.

how good or bad would this work in my tower that has 2.239 Ft3 even though the woofer optimum sealed volume is  2.92 ft.³? my tower has a 2 inch tweeter and a 4 inch mid range if that will effect anything . 

Asked by: Crazzed335
Yes this will still work in that volume as long as it is sealed.
