Thanks BigWill,
I am also wondering about subs, crossovers, and squarewaves. The bigger the speaker, the higher the mass, the more difficult it is to 'turn around' so sounds like percussion aren't as sharp. Conversely, you need a large excursion to get the low notes and larger speakers can better move air around.
I am really trying to find a system that would accurately play music one moment and the "rock the block" with a DVD explosion the next without me having to reach behind the sub to adjust the settings. I have a CD that has previously revealed ugly sounding subs: Billy Cobham's "Warning". The last track has some syth bass notes that sound all uneven if your sub settings aren't damn near perfect.
