id be interested to see how this thread develops, as in the past i've always liked the sound of single 15" speakers, however as I'm on the lookout for a cab, I'm considering other configurations. The favourite so far has been the markbass 4x10, but like I said I'm still looking. The 2x10 and 1X15 sounded good (ashdown abm), but i wasn't so sure about the 2x10 configuration on its own.
