AFA how big a leak it takes to basically delete the vast majority of box loading it's as little as air leakage around the mounting bolts and T-nut threads, but an air leak around the driver ~completely negates any box loading.

Thanks GM....No, there is no sealant around the XO panel or the driver....The XO panel and cabinet mating surface were milled so they basically seal, but I guess without a gasket of some sort, it would not be completely air-tight....I'm sure there's leakage around the driver as well, but it never occured to me that such a minimal amount of leakage could impact the loading of the cabinet to this degree, particularly with such a big cabinet, and large driver...

If a small amount of leakage can impact things so drastically, I think my initial steps at this point will be to install a gasket in the XO panel, and a gasket behind the driver to make sure the cabinet is sound...Then I'll get an amplifier and different CD player to rule out the obvious...

From there, I guess it's back to the XO...

EDIT: I may have to correct myself, but I'm on my way to the airport, so I'll have to validate this weekend...It's been a while since I installed the drivers, but something tells me that GPA shipped a neoprene-type gasket set with them...I'll pull the driver and see if they're installed...
