Goldwood GW-410D 10" Poly DVC Subwoofer
I have of db Plus 880 2-way speakers with rotten 10" surrounds. The specs say 35-22 khz. Efficiency of 96db @ 2.83 V and cross-over point is 2200 hz. Would these 10" Goldwoods be a good replacement woofer? If not what would you recommend?

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.
