My current rig is an SVT pro 5, a Shro 21012L and a Shro BMF1215. I run stereo out of the SVT since the cabs are 4 ohms a piece. I'm getting about 400 watts per side, according to the Ampeg's manual. This is my outdoor, big stage, most volume rig. Inside I can run bridged and only run one cab, if I don't need massive volume. I'm considering going lighter weight (class D) amp setup. I'm looking hard at the Shuttle Max 12, but I'm a little concerned about how the SM will sound with the Shroeder cabs. I'd like to hear what amps you Schroeder cab guys are using and I'd like to hear you're opinions on what amp may be best suited for these cabs. It's a failry new setup to me and I've only got a couple gigs on it.
