Well having listened to it for the first time tonight at a private audio store in Indiana. I can attest. THIS THING HAS PUNCH ! It was hooked up to a simple 702 B&W, X-over at 50 hz with the master volume at 0 and 0 phase, with enough gain to pressurize the room. Its fast and tight . It may be the best sub I have heard. Never have I heard that much tight punch and pressure from a over sized 12 inch driver. I would love this in my system to try. However at $$4000 its not cheap but world class sound isn't either. The sub has all the fancy EQ and mic. for room optimization. It even has a sweep mode that tests for you. The Black Lacquer is not my cup of tea but it seems well built. Overall this sub is in a class of its own.
How about 20HZ to 86 with no loss of DB and -3 at 18hz This thing is for real !
