One more contender????

I have all but decided on the driver I'll use thanks to the help of many. Thomas W and Rick, thanks a lot.

BUT......I found this (15") driver, modeled it for an active EQ'd sealed box HT app and liked it for the extra SPL it presented, with linear excursions to match what has been considered up to now.

A little bigger box, .65 Q, 78 liters and 106dB at 20. And a 2 ohm load that mates well with my amp. Is .65Qtc too high for this app?

It's new and yet unproven, but a very good TC Sounds product. Not trying to talk myself into it or out of it. I'll take suggestions/opinions.
