I currently play an Ampeg v4bh with an SVT 115e cab . I want to get more volume(already had another 115e stacked on it but due to limited space in my car I can't do the second cab). I have the chance to get an SVT212e off Craigslist for $60! I've never even heard of the cab, and only found a couple short threads on TB. Its same specs as the 115e, 8ohm 200watts. What should I expect in terms of volume difference?
