Just got back from GC. I traded in my two S.O.B.'s and goliath III for an Ampeg BXT 410 hl and BXT 115 hl. Wow! These cabs sound excellent! Typical Ampeg "thunder" on the low end and nice and crisp on the high end. The only down side is they are both 4 ohm cabs, so I can not bridge them with my SVT IV pro. Combined with my 610 hlf, I won't have to worry about being heard.
