I am unsure i anyone will ever run into one of these. Its an off brand sealed 2x12 with diagonal speakers. Got it unloaded on ebay as a local pickup. Its a powerful, punchy cab made of super thick plywood. Front liading in the 80s style.. I ttok thw dampening fiberfill out so she has some resonances now. Can get boomy with 55hz bass cone speakers. But she sounds great right now loaded with a cts alnico and celestion greenback. Truly a rock n roll cab. Gets some 4x12 punch! Kinda heavy though. Bad tolex and grill cloth work though. I still will never part with this cab. She records really well.
just go on stagecraft.com and order a diagonal 4x12, its almost the same as this cab, just a little bigger so the front's a square...it'll be like 350 bucks I think and then you'll need 12"s.
you'll probably want some nice tube heads too.... not sure why one would need a big, sturdy closed back cab unless they have some powerful tube amps that need speakers... I really like 50 watt british type amps with this style 2x12
