It seems like the old-school 15" cabs are back in style these days. I guess a lot of people have rediscovered the old Sunn and Acoustic 2x15's, and I've seen some folks using 1 or 2 of the old Musicman 1x15's. I've played a few big old 2x15" cabs in my life and I always liked the big thick sound you can get out of them and how they stay full sounding even at a distance. So here's my question: is there really anything different about the old cabs vs. new ones. I have a 1x15" Avatar that I think is pretty cool--it's a solid, well made box correctly tuned (I usually keep the tweeter off). Should I just get another one and have my vintage rig that way? Sure, it's not as vintage-cool as an old Sunn box, but is it going to sound about the same? Except for the big folded-horn monsters like the V4 cab, aren't all these boxes really the same? Or am I missing something?
