Goldwood GW-212/8 12" OEM Woofer 8 Ohm
Goldwood GW-212/8 12" OEM Woofer 8 Ohm is rated 4.3333 out of 5 by 78.
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

Rated 5 out of 5 by from Excellent investment!My pair of Advent Loudspeakers (circa 1977) were a great investment then, and have evolved into treasured possessions over time.One of them had a blown woofer - essentially, the foam had fallen prey to age and dry rot. A trusted friend recommended Parts Express to me - and after getting acquainted with the website, I selected and ordered the highly-reviewed Goldwood GW-212/8 12" replacement woofer. It dropped into place flawlessly, all the mounting holes lined up perfectly, and the sound is amazing...the process was quick and simple, and the shipping was faster than I had expected. I heartily recommend this woofer - and Parts Express - if you are looking for great audio value and performance. When my other speakers need new parts - I know where to go!!

Goldwood GW-212/8 12" OEM Woofer 8 Ohm

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.

Response data for BassBox?

Hello,I'm just wondering, is there any file I could use to import this driver's freq. response to bassbox? It just keeps giving me response up to 20khz (-18Db), whereas the graph says it should be around -40Db...Thanks!
Asked by: XENGS
The Bassbox graph is simply a modeled graph which means anything above 300 Hz is meaningless for the program. The reason it is showing flat response up to 20k is simply because there is no Le applied to the driver parameters, this figure is also not important in caluculating enclosure size. If you type if the Le figure of "2 (mH)" for example you will see the upper end of the driver roll off.

mounting hole dimensions

I read in existing q & a that the mounting screws are 11.5" across the cone. The listed hole cutout is 11". That seems kinda close to me. My current cut-out (sony ss-530) is 10.5". Will this fit, or do I need the entire 11 inches? Thanks

It is always best to use the manufacturers specificatiions to prevent unseen consequences.

sealed or ported box?

Asked by: fordtec03
Sealed, this woofer has a really high Qts 1.44 that means your get a large peak in the bass response, porting it only make it worse. Try to stay above 1.5 cu ft internal with this one. At 1.5 cu ft your looking at a 7dB peak at 75 Hz, 3 cu ft and its a 6 dB peak at 60 Hz. In an infinite baffle configuration it will still have a 3.5 dB peak at 45hz.
