There's a Bag End 2x12 for sale in the TB classfieds. I don't know jack about specs, but I found these on Bag End's website. Sensitivity (in dBspl) -- 1 Watt/1 Meter 103 Frequency Response -- 50-5kHz How are these numbers? I'd be using this with an older GK400RB head. Currently using an LDS 1x15, which is 8 ohms and weights around 45 pounds. I had a Bag End 1x15 when I first started years ago, and I really dug it. I realize this is a beast at 77 pounds, and I THINK I'm willing to deal with that. Play a P and upright in a jump blues band, if that influences anyone's opinions on what this rig would sound like. Thanks!
