I picked this up as a fill in when I moved and sold off my mass of vintage gear. This cab is loaded with an Eminence Kappa Pro 15A. It looks like a Carvin cab (including Carvin backplate & RL style tweeter) but I can't guarantee that it is. It has an L-pad hooked up to the high range driver and it works really well. This cab's low end rolls off quite a bit like an Ampeg SVT 810E would including a 120hz bump but overall it has a cleaner character. With my QSC USA 850 the thing puts out an insane amount of volume without farting out.
8 ohms, 500w thermal handling, ~ 250w RMS power handling, 101 dB @ 1w/1m. Probably around 60 pounds.
$80 or an SM58 takes it all. Seriously, that's a ridiculous deal for a working 115.
