how can a cab be super flat AND have a big bloomy bottom? bit of a contradiction in terms, eh? and we've already discussed how impossible it is to have a "super flat" cab. how flat is "super flat"? come on rp...you're slipping![]()
Two different concepts... 'flat' just means no big peaks or valleys WITHIN A SPEAKER'S FREQUENCY RANGE. So, a box can be flat between 100hz and 2K... like a little 115 box, for example.
That RANGE can vary greatly among cabs. The Acme is tuned/built to go all the way down to 33hz or so... right around the fundamental of an open B string (hence the name 'Low B'). While the Acme's seem relatively flat across their wide range, that huge low end extension can actually make them sound unbalanced on the gig, since many times you need a peak in the mids and a roll-off down low for the cab to actually SOUND balanced (i.e., the small 5" mid driver and very small soft dome tweeter just don't seem to have the SPL capability to balance that cab out in a difficult, boomy room at high volumes).
