I'm seeing these cabs at 399! An ampeg 210AV is 299, and i'd bet it's categorically better than either. A genz benz focus 112 is 349. Hell a gk neo 112 is 399.
If there's something about these rumble cabs that really floats your boat, cool. But the GC pricing i found says there's better for equal or less money. and that doesn't even count shopping used gear. for what those rumble cabs cost, i'd suggest another route. IMO, IME, AFAIK
, My $0.02, and 2ETO. good luck.
