The 8" version has more Xmax, and way larger motor, and more Sd, since its an 8" sub. Also, its cheaper by 10$.

How do you all think this driver compares to the silverflute http://www.madisound.com/silverflute.pdf
W20RC38-04 at the very bottom left of that page.?

I'm also thinking of using it as a car stereo midbass. The TB has good excursion but only 84 db sensitivity. While the SF has 93. Of course I have no clue how that is measured or at what frequency but it seems like its a significant difference. Maybe i'll just buy both sets and try.

I built a small sub for a friend using two of the TB W8s in a 45 liter enclosure. He's quite pleased with the results. Also, the latest issue of Audio Express has details of some "apartment subs" utilizing different brands of 8" woofers and the TB setup had the better results.

I simulated two W8-740C in >30 L bass reflex enclosure tuned to 14 Hz. Reaches ~15 Hz 95 dB SPL. With a proper low pass filter it reaches 15 Hz -6dB and 18 Hz -3 dB.

I built using the W8-740C, and in ~1cuft with porting, it makes lots of boom-like noises.

I used a homemade mono paralleled LM4780 gainclone and a cheap Radio Shack transformer to power it, too.

I think it cost me about $70 or $80 CDN after everything to build, and the results are pretty darned awesome. People who hear the system (has W3-871S-based LCR speakers teamed up with it) are shocked at how small everything is, and yet how (nicely) noisy it can get.

So, yeah. Buy the W8-740C -- wicked-good bang for your buck.

Cheers,

Chris
