Goldwood GW-410D 10" Poly DVC Subwoofer
What effects are resultant in putting this driver in a box tuned and vented at an F3 of 28 Hz as that is below the free air resonant frequency?
There are many variables that play a roll in how a woofer reacts to a tuning frequency lower than it's Fs. This woofer is a fairly bad example due to its high Q and large box requirement which requires a low tune for a somewhat smooth response. In this case the only downside is the lack of driver excursion so it will have problems with as little as 20 watts. Usually this type of woofer will work better in a sealed cabinet, but in order to get the most out of the power handling they cannot be used very low in frequency.

For home theater use; using 50w max amp. would this produce good sound in a 2.5cu.ft sealed box?
This woofer will work in the volume but it will only play into the mid 30's in room and reach excursion limits quickly limiting its output.

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.

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

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

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!!
