Goldwood GW-406D 6-1/2" Poly DVC Subwoofer Shielded
What would be the recommended passive radiator for these in an optimum vented cabinet with voice coils in parallel? I want to build a 2 way garage speaker. I already have some piezoelectric tweeters and one of these speakers from another project.
I would recommend the Dayton Audio SD215-PR.http://www.parts-express.com/dayton-audio-sd215-pr-8-passive-radiator--295-492

Does Parts Express sell an amp and low pass crossover that would work well for this? I made a portable radio, but it doesnt have as much bass as I want, so I want to make another portable box with this subwoofer in it.

With a frequency response of 59 to 6,000 Hz, this "sub" would seem capable of handling the full 69 to 2,093 Hz range of a five-octave keyboard. Right? Or is there something I'm missing?
Yes you are right. This is called a subwoofer but it does have an extended response, so this will work fine for that application.

I just have a question on the specs I see on this page. Is the 91.3 db sensitivity listed for both voice coils driven in parallel representing a 4 ohm load to the amp or is it for each voice coil running at 8 ohms? Thanks.
All specs on this driver are derived with the coils wired in parallel.

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
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
