Goldwood GW-406D 6-1/2" Poly DVC Subwoofer Shielded
Goldwood GW-406D 6-1/2" Poly DVC Subwoofer Shielded is rated 4.3721 out of 5 by 43.
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.

Rated 4 out of 5 by from Decent MONSOON sub replacement!Based on the review below I replaced the Monsoon (overrated by the way) sub speakers in my 2000 Trans Am. It took a little bit of work to mount them as the holes didn't exactly line up. The stock speaker is a 6 3/4 while this is a 6 1/2. Took an hour tops, including soldering time, drilling new holes and cranking some Iron Maiden! Not the best bass I've ever heard, but for $15 what more do you want? It's my wife's car and she's plenty happy now, happy wife, happy life!

Rated 5 out of 5 by from Good sub for the money. 1998 Pontiac Trans Am MonsoonI replaced the stock subwoofers in a Monsoon sound equipped 1998 Pontiac Trans-Am with these and am very satisfied. They sound great. bolt hole did not line up perfect, but close enough! Very easy install!

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

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.

Dear PE: Voice Coil Impedance 4 or 8 ohm each

I know the specs state 4 ohms per coil, but I have seen incorrect specifications before.Looking at the Woofer Selection Guide his woofer impedance is listed as 8 + 8. The note before the specs reads, "All parameters are with voice coils connected in parallel." Also if you click on "Goldwood GW-406D Specifications" The Parallel Re is 3.5 ohms, and Series Re is 14.3 ohms. This leads me to assume the voice coils are nominally 8 ohms each, but assumptions always get me into trouble.
Asked by: Doyne5
This woofer is 4 ohm per coil as insured by measuring them on the DATS system. They each show a DCR of 3.9 ohms.

amp

can this be powered by one of those lepia small amps and should any kind of passive crossover be used?
Asked by: jalng63
The lepai amps are a little on the weaker side for this subwoofer. But if you insist on getting one I would suggest the 4x45 watt RMS one or the cheaper one with a separate subwoofer line. I have the Lepai 4x45 watt model and it works well but it doesn't have enough power to fire my 6.5 inch tang band subwoofer efficiently. And that runs at about 45 watt rms. so if you do end up buying this goldwood and a lepai amp, the sub won't be very loud compared to any mids or tweeters hooked up with the sub. The sub and/or bass will most likely be drowned out by the higher frequencies due to the efficiency of the sub compared to other more efficient tweeters. That's where your crossover comes in, but still this isn't a very efficient sub for smaller systems.
