Swerd, I have down business with Ascendant in the past The
subwoofer I built used an Ascendant Audio Atlas 12" and it is phenominal. They are making a name for themselves in the DIY community.
They are not finished updating their site yet so all of the information is not there. The prices are toward the bottom of the page in red.
$155 each for the MTM with all hardware/crossover parts plus the flare port.
I trust them to sell a good quality product. If their subwoofers are any indication, the Arbiter's should be excellent. As I said in my original post, I will be calling them to get more information. Their website is sort of a mess right now.
