I had a couple of 12s but the 15 is just low end heaven to me. There's something about the air it moves that just feels bass to me. Hard to describe but the 12s are great, don't get me wrong. They just aren't 15. I love the 15 with my 210.I just pulled the trigger on a 350 combo and a second 10-2 cabinet. As I am mostly a five-string player, I'm considered adding either a 12-3 or 15-3 as third cabinet for some fuller lows. Question is, which one to get? Would love thoughts. Usage is primarily to serve as my at-home practice sonic heaven rig![]()
