The woofer looks like the woofer used on the Performa3 series from Revel? Its only 6" though?
Definitely an SB Acoustics woofer. I have tested a few of their various models, including the line you're referencing. I imagine the drivers are not "off the shelf" but rather tweaked for the manufacturer's spec. But they are definitely SB made judging from the magnet, the spider and the cone (the spider looks like the same type used in their Satori line). I just got mine in for review and cracked open the case. Even the passive radiator looks like this SB made PR.
Not that any of this is bad. Just saying, it's pretty clear the woofers are SB. Not sure about the tweeter (didn't get that far; will later).
