I think a few of you on this thread need to listen to some good bandpass setups before dismissing them all as rubbish. For example, Alumapro made a little bandpass setup similar to this years ago that actually had pretty good SQ. Its prefab bandpass enclosures that ****, because the generic design almost never matches the unkown driver added later. But Id be willing to bet MBQ did a little homework on the design before slapping it together. Cheesy? Ya. But like Punk said, without a listen, you really shouldn't dismiss it as poor SQ.
