So, I've been toying with the idea of getting about 4 1x10, 1x12, or 1x15 cabs and creating a tall stack. I can think of quite a few pros and cons to the setup, but what I'm really curious about is low frequecy response. I've read discussion of multiple cabs seeming to have better bass response than the ratings on the individual cabs would lead one to believe. I've also read discussions of line arrays and the Dead's "Wall of Sound" approach. Obviously, this wouldn't be that big, but what do you think? Would the sum of the parts allow deeper bass reproduction than the individual cabs? Thoughts, caveats? Anyone have experience with a setup like this? Thanks!!
