Goldwood GW-410D 10" Poly DVC Subwoofer
What is the size enclosure for this woofer? Should it be acoustic suspension or ported? If ported what diameter and length port should be used?
This particular subwoofer is well-suited for a sealed alignment. The optimum enclosure should be approximately 2.0ft³ internal volume.

Possible use as mid bass?
If I put this in a box with a resonating frequency around 75 for midbass, where would you fellas suggest crossing it over, and would I need to do a bandpass crossover?
This driver has a sweet-spot between 80 and 1000 hz. You would need to plug the specs into a box calculator to play with box types. But ideally, it would be sealed and requires 4 cubic feet. The T/S of this driver does not allow for a ported alignment so a resonant frequency is moot. And yes, you need a low pass and high pass crossover on the driver. When you don't properly crossover drivers, they overlap and create time smear in the range they share. It muddies up the sound - imaging and staging.

Replacement for Cerwin Vega RE25?
Hi, I have a pair of Cerwin Vega RE25 speakers and I am missing the woofers. The original specs. call for 6 ohm 150 watt max woofers. Are these a good replacement for the Vegas and can you reccomend any other woofers you sell as an alternative as well? Thank you. Clark
You have come to the Cerwin Vega man from DownUnder! Ahhh The Cerwin-Vega RE-25 model of audio speakers was launched in 1995 as part of the company's RE, or Reflex, series. A floor-standing model with a manufacturer's suggested price of about $600 per pair, the RE-25 was considered a high-end home audio speaker. Although this model is discontinued, it is still available on the used speaker market...Basic Specifications"The Cerwin-Vega RE-25 is a three-way stereo loudspeaker that includes a 10-inch cast aluminum frame woofer, a 4-inch cone mid-range and a 1-inch polycarbonate dome tweeter (low range). Each speaker weighs 40 lbs. and measures 27 1/2 high, 12 7/8 inches wide x 11 1/2 inches deep. The cabinet is made of composite board and finished in black ash.Power and Performance"Cerwin-Vega RE 25 speakers are rated for 100 watts RMS, with a minimum of 5 watts and a maximum of 150 watts. Frequency response for the drivers is measured at 38 hertz to 20 kilohertz, and crossover frequencies are 1 kHz and 6 kHz. The speakers are rated for 95 dB sensitivity for 1 watt of power at 1 meter. Impedance is 6 ohms...Additional Features"The tweeter of the Cerwin-Vega RE-25 model is protected by a self-resetting PTC polymer fuse, and the woofer is protected by a fuse as well. Heavy duty 5-way binding posts are used to connect cables from the receiver, and the enclosure is of bass reflex type.Practical Considerations"Cerwin Vega RE25 speakers are upper-range home audio speakers that are sold on the used-speaker market. They output sufficient volume to handle most home listening needs, and their wattage rating is ideal for home audio receivers...just had to get my literature out on CVRE25...So as thus to seeing the specs of the model of CV you have, The driver you have chosen is a dual voice coil "subby" a Goldwood GW-410D 10" Poly Sub-woofer the CV RE25 driver is a single coil "woofer" not "sub~woofer" So you have to get a woofer as same spec as you can to the CV driver i would choose the Dayton Audio DC250-8 10" Classic Woofer 2 of those and your in utopia and they have Rubber Surround so you don't have to worry about "surround foam rot" EVER and Extended lows just like the CVRE10 driver and only $29.89 each just super, right on Clark...Rock on, Parts Express!!

What plate amp would be ok for this sub?
Our SA100 would be a good choice for this woofer.

What is the impedance of the coils- catalog says 6,web says 4?
The catalog in this case is incorrect, the website is correct.

I have a two channel amp that is going to be dedicated to one of these sub woofers, should I wire one channel to each coil, if so would that be 6 ohm each or 12? It's a small t-amp 25W channels, for a portable setup.
I would wire one channel to each coil which will be a 6 ohm load on each channel.
