Goldwood GW-406D 6-1/2" Poly DVC Subwoofer Shielded
Goldwood GW-406D 6-1/2" Poly DVC Subwoofer Shielded is rated 4.4 out of 5 by 45.
Rated 5 out of 5 by from Goldwood subwoofersI had a Cambridge Soundworks subwoofers (2) in a box that had shattered from power. The Goldwood subwoofers were twice as heavy and perform much better with the Dayton 25 Watt subwoofer amp I installed right in the box.

Rated 5 out of 5 by from Yamaha sub woofer speaker replacementI have no problems with the speakers at all... bought speakers 1/2 smaller than factory but they sounded just as good.

Rated 5 out of 5 by from Great sound for a great priceI bought one of these five years ago and it worked great. I had to replace recently and bought the same one again. Works great and is very reasonable in price.

Rated 5 out of 5 by from Another Firebird Monsoon ownerI think this works just fine as a replacement, depending on the source I keep the bass flat on the eq, or even turn it down a little. I have a tip for easy installation: instead of trying to drill new holes in the speaker or car, I used heavy duty cable ties to fasten them. Put some rubber or foam around the edge where the speaker makes contact so you don't get any vibration and to make a tight seal.

Rated 3 out of 5 by from Ooooppppss! Mis-read the specs!This little guy is a sub that is only rated to 59hz..? Sounds more like a great mid-bass driver. Using it in some custom furniture, it should do alright.

Rated 3 out of 5 by from Sounds More Like A Woofer than a SubwooferThe woofer or subwoofer has mediocre bass and I might as well buy something that offers better frequency response and can pump bass. I am going to try to experiment with it. I don't know if I need to replace the Pioneer antique CX-44 crossover with a real subwoofer crossover that really has some really deep bass and hope to shake the apartment. I have another speaker that needs upgrading as well, because it's a 6.5 inch stock subwoofer that measures 3 ohms than 4, 6 or 8 ohms. So I am going to upgrade both passive boxes with a subwoofer crossover and 4 ohm speakers. I would recommend this subwoofer for a starter subwoofer with a real good subwoofer crossover not a regular speaker crossover of which I have.

What would be the recommended passive radiator for these in an optimum vented cabinet with voice coils in parallel?  I want to build a 2 way garage speaker.  I already have some piezoelectric tweeters and one of these speakers from another project.

Asked by: Steve K
I would recommend the Dayton Audio SD215-PR.

Does Parts Express sell an amp and low pass crossover that would work well for this? I made a portable radio, but it doesnt have as much bass as I want, so I want to make another portable box with this subwoofer in it. 

Asked by: Amp Question example, would this amp work well? What crossover to use with it?

With a frequency response of 59 to 6,000 Hz, this "sub" would seem capable of handling the full 69 to 2,093 Hz range of a five-octave keyboard. Right? Or is there something I'm missing?

Asked by: Chronic Iguana
Yes you are right. This is called a subwoofer but it does have an extended response, so this will work fine for that application.

I just have a question on the specs I see on this page.  Is the 91.3 db sensitivity listed for both voice coils driven in parallel representing a 4 ohm load to the amp or is it for each voice coil running at 8 ohms?  Thanks.

Asked by: 1957Teddy
All specs on this driver are derived with the coils wired in parallel.

i was wondering if anyone had experience using this speaker as a mid bass/ mid range? i understand this is a subwoofer but the specs say it will reach out to 7000 hz, if they had is the tonal balance good or does it sound harsh like a typical subwoofer 

Asked by: hiviman1
If you open the graph below, you can get a better idea of what this will to in the upper range. It is very flat to about 1,200 Hz but has breakup issues beyond that. This may work well as the woofer in a 3 way, although I would not recommend crossing it higher than about
