So before hitting TalkBass, I never had heard of comb filtering or optimal cab volume (size, not sound) for driver sizes. Do things like this REALLY have a considerable role in our sound? Major label acts are still touring with 810s (not in a vertical array mind you!) with cabs that most likely aren't big enough for the speakers in them if you follow equations. But they are still the standard. Then we have crazy cabs that have different speaker sizes in the same cab... and by the books, that must be asking for trouble, right? I'm just curious to see how players (not engineers) have experienced these factors and if they found them significant enough to take into consideration. Not trying to flame any of the numerous engineers here either, I'm just curious.
