Alright, I am aware that the Avatar threads have been done to the fiery furnace and back, but i've tried a search, and I can't find the exact information I'm looking for. I currently own an Avatar 210, and I have no complaints, but I may be getting a gig with a hardcore outfit soon, and my 210 just isn't going to cut it. I'm looking into a 212 or a 115 to stack it on top of. I need articulation and low-end, and I want to know if the Avatar 15 is fast enough to keep plenty of clarity to my sound. Many players here are advocates for 12's as a replacement for 15's, but can they really provide low-end comparable to a 15? I'd appreciate any information you could give me. Thanks. Edit - I think I should as specific as possible, so as to avoid wasting anybody's time. I know there are plenty of quick 15's out there, I have played some of them.....I'm wondering about the Avatar 15, and how it compares to the Avatar 212.
