I've been playing my M-Pulse 600 through a stacked pair of Mesa Scout 15 cabs. It's been just right for the loud oldies band I'm in, although my sound's been a bit on the boomy side. Then recently I played the same amp through a single Powerhouse 115. I thought it sounded great: loud and clear, with plenty of bass yet more clarity. The PH115 is a heavy bugger. I'm wondering now if I should sell off all three of these 15s and invest in a pair of Powerhouse 112s. I could stack them when I need to, or carry just one when that's all I need (probably with my Walkabout). Mesa doesn't list weights for these cabs. Can anybody describe whether the PH112 is really an easier carry than the PH115? And how about the sound difference? Thanks!
