I have a Ashdown ABM 4x10" cab, but it seems that everytime I play a cab with a 15" speaker, I get a more growly sound that I want. The problem is that with the 15" speaker my slapping doesn't sound as good and fast playing gets muddy. How are the 2x12" cabs? EBS offers one for a good price, I should test it soon. Are they the best compromise between the attack and clarity of the 10" speakers and the bottom from 15" speakers? The EBS 2x12" has a tweeter, so I think that slapping will sound good. All comments about 2x12" cabs(and even 4x12") are wanted!
