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.

Goldwood GW-406D 6-1/2" Poly DVC Subwoofer Shielded

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 1kHz.www.parts-express.com/pedocs/more-info/290-352-goldwood-gw-406d-more-info.pdf

Ported enclosure sizing question

I am designing a stereo boombox and would like to include the option to run it as a 2.1 when I'm in the house. I would like both enclosures to be the same size for aesthetic purposes. That would mean the internal dimensions of the sub enclosure are: 16" x 7" x 5.5" yielding .356ft^3 volume. Some of that will be taken up by the plate amp, so let's assume the volume is around .325ft^3. I don't have the software or knowledge to calculate port dimensions, so I was wondering if someone could help me do that. It would be great if we could get the f3 in the low 30s but I understand that the task may be impossible given the price of this sub and my small enclosure. Thanks for the help. Hopefully I'll get a response and I can post this "2.1 boombox" to the techtalk forums.
Asked by: tycham85
That volume is quite a bit smaller than what is recommended so the tuning will have to be a bit higher. I would recommend a 1.5" diameter, 4" long port which will tune the enclosure to about 50 Hz. You could also leave it sealed and get a much smoother overall response.

Is this a good match with Dayton SA25 25W sub plate amp?

Would this speaker work well with the 25 watt Dayton plate amp SA25? If not, are there other low cost subs that would match up well? Thanks!
Asked by: steveoh
This would work well but only if the woofer coils are wired in series to present an 8 ohm load to the amplifier. This will create a loss of output power but likely not enough to be noticable. You may consider our Dayton DC160-4 as a suitable substitute. It will allow the most amplifier potential and work well in small vented or sealed boxes quite well.
