I'm selling my SWR900 and (2) 4x10 Goliath cabs to reduce weight. Still considering Markbass but leaning toward Mesa Subway Cabinets. I'm primarily a classic rock player. Looking for recommendations on a 1x15 with a 2x10, or should I get (2) 1x15's?, or maybe a 1x12 for my second cabinet when needed? I'd most likely buy the TT80 if I go with Mesa.
