Goldwood GW-412D 12" Poly DVC Subwoofer
Goldwood GW-412D 12" Poly DVC Subwoofer is rated 4.0455 out of 5 by 22.
Rated 5 out of 5 by from great for cheap OB designI bought two of these and paired it with the Visaton FR13-4 5" on a flat sheet of plywood 39" x 24" .The Visatons are driven by the Topping TP22 amp. I used a 200 hz high pass Fmod. Because of the DVC I wired these sub in parallel for a 1 ohm load and am powering it with the clearance Technics amp. (100watts @ 1ohm.) the amp gets barely warm. The goal was to build the cheapest OB that I could. Mostly unfiltered, I am impressed with the bass punch, which I have heard was tough to get with an OB design. I feel it in my chest 12 ft away. I am going to run a Vifa textile tweeter crossed at around 4000 hz to enrich the highs. I have no way of measuring this yet but if it only can get better with some proper filtering I will be happy. I chose this woofer because it was cheap and on sale. Also the sensitivity and flexibility in range gave me some full range options. Since I figured I would need a sub for anything lower than 40hz I was ok with the FS. very impressed with the strength of bass. When it stops raining I will take them outside to see what they really will do. The sound is definitely more open, jazz, swing, Big band and acoustic sound incredible. The room I am presently listen to these in is 16 x 33. Presently listening to some acoustic blues. the bass notes are very clear and well defined.

Rated 4 out of 5 by from great bandpass wooferfor all of you who think that this sub sucks, it is because it was probably in the wrong type of enclosure. this would be a perfect subwoofer in a band pass system tuned @30Hz and coupled with a shaker system, would make a very affordable and discrete sub harmonics system. just use the right box, and it wont dissapoint. i mean just look at the Xmax and you can tell it wasn't meant for a ported box running any higher than 80 watts max/120 watts program.

Rated 2 out of 5 by from wasnt even pushin it and it blewI thought it was ok then it blew not even 105 watts of power, but since it is a cheap speaker can't be that dissapointed in it.

Rated 4 out of 5 by from good deal on a wooferthese are good as the woofers I was replacing. They did not quite give me the subwoofer punch I was looking for so I was a bit disappointed in that. So if you are looking for some good woofers, these are great for the price.

Rated 5 out of 5 by from GREAT WORKING SPEAKERSthe speakers sound "GREAT" really play that "ROCK & ROLL" GREAT! really handles the lows well! thanks!

Rated 4 out of 5 by from Solid Value SpeakerHey, bought this speaker to install in a vehicle, and mounted it in a sealed enclosure. Delivers a sharp, crisp sound, but does not go quite as low as I would hope. However, if you look at the specs, it states that it performs in the woofer range, so this is expected. Also, if using this as a subwoofer make sure to use a good crossover, as the mids will come through very defined if they are at all present, muddying the lows.

I have a 2.25ft3 enclosure. What port diameter and length would be good for this speaker?

Asked by: sem613
A 3" diameter, 6" long port will tune this to 31 Hz.

Would this woofer work better in a Sealed or ported enclosure? I am using it in a 3 way tower speaker. Also what would be an ideal crossover point between this and the GRS 8PF-8 8" paper cone?

Asked by: Jinonyx
These will work best in a sealed enclosure from 2-3 cubic feet and heavily stuffed. It will handle a crossover frequency from 200-1,000 Hz, but generally a woofer to mid is around 350 Hz.

BandPass enclosure specs

I would like to mount this on a baffle mounted in the center of an 8 cuft car trunk. The baffle would run front to rear, the trunk would be the enclosure, I would seal the baffle so when the trunk lid is closed the front is sealed from the back. The trunk has two tunnels that run on either side of the fuel tank up to the passenger compartment. The tunnels are roughly 5" x 5" x 15" long. I can mount and seal PVC pipe into these tunnels if necessary.I realize this isn't optimal but the car is a Mazda Miata, there isn't any other space really. I do realize I will have to damp the trunk.Is there a better woofer for this application? I'm not looking to shatter windows, this design will be easily removable and actually take up less space with no additional box.
Asked by: CoolP
First, there are specific demands of mobile components. Temps up to 140 degrees and down below freezing are one, moisture and humidity are the other... Then - as you know - the car can rattle, and without tearing it apart to turn it into a cabinet - how do you get good bass? The Goldwood is not designed for mobile use. In the search field at the top of the page, type in "auto subwoofers" and it will appear as the third category with 4 different sizes. That's your starting point in selecting a mobile subwoofer
