So far, with the Markbass F1, I am delighted with it. The dimensions are 27"H x 14"W x 15 3/4"D and weights 50lbs. The bottom end from the two 8" drivers is pretty amazing, almost too much, and even with the M/H driver fully attenuated with the pad (nicely placed on the side of the cabinet to not have to reach behind the cabinet to adjust) the speakers have a nice sparkle to the high end. With the M/H driver at the "normal" setting of the pad I can get a wonderful aggressive grind to the mids and high end. This is a 4Ω cabinet so I can get the full 500 watts from the F1 if need be; it can handle the 650 watts from my Walter Woods, too.
At the moment this is the only one in existence. Come on by and try it out!
