Rated 5 out of 5 by from Good speakerI bought this as a replacement for a KLH speaker in our home stereo system. It was a perfect match to the old one. Sounds great!

Rated 4 out of 5 by from As Good As NewThought I would try one of these as a replacement for my blown woofer in my Cerwin-Vega HED-12's. The mounting holes were off slightly and had to be re-drilled for the install. Once installed the speaker sounds as good as the original one. I think it will sound even better after break in.

Rated 5 out of 5 by from Goldwood 12" OEM Woofer conesI contacted Parts Express for technical support and a recommendation on a replacement 12" woofers for a pair of Infinity 4000 cabinets. This was their suggestion; we placed our order; the parts arrived on-time in excellent condition. They sound just fine and the price was very reasonable. Should the need arise for additional components, I will call them first.

Rated 4 out of 5 by from As advertised.I'm happy with the product. When my circa 1996 speakers became dry-rotted on the outer ring, I could either buy replacement rubber for as much as these speakers or buy new speakers (and a whole new system to get similar sound) or these. These are superior to my eye (heavier magnet, thicker rubber, etc) than the Sonys that came out.

Rated 1 out of 5 by from un happyI bought two of these in November 2013.put them both in a set of 200 watt tower boxes. The mids and highs put out more sound than the 12'inch subs.I called for support....NO help or solutions were offered. Don't waste your time or money with these

Will replace this woofer nwx-1245

Asked by: Acoustic
I am not familiar with that model. In general it is best to start by matching up the cutout size and the woofers frame diameter. It is best to contact with those measurements and we would be happy to help find a suitable replacement.

What would be a good cross over frequency pairing one of these with 1 GRS 8FR-8 to build a low to mid range cabinet to compliment the Dayton BR-1 kit?

8ohm or 4ohm Recommendation. MY 1ST QUESTION WAS MISUNDERSTOOD.  Between GW-212/8 12" or  GW-212/4 12" (Sealed 3 Way with (1) 12'' for L spkr and (1) 12" for R spkr); Yamaha Z9 AMP (no issues with 4 ohms) Which speaker would you recommend and why?

Asked by: Johnny Nobody
If the amplifier has no issues with a 4 ohm load this would be my recommendation. You get a slight advantage in sensitivity with a 4 ohm load which means louder with less power. Make sure the crossover is designed to work with a 4 ohm load.

8ohm or 4ohm Recommendation. Between (2) GW-212/8 12" or (2) GW-212/4 12" (for a Sealed 3 Way); with a Yamaha Z9 AMP (so no issues with 4 ohms) Which speaker would you recommend and why?

Asked by: JNobody
In most cases you want to wire two woofers in parallel when possible do boost the sensitivity. As long as the mid and tweeter will keep up with the output, this is the way to go.

would this replace a speaker that is mounted with only 4 holes/screws?

Asked by: jeff in lawrenceville
That would work if the four holes you have align up with the holes in the speaker. Why not just drill holes for the speaker. That would prevent you from bending the basket so easily.
