Sorry it's taken me so long to get back, Sunn fans, I've been having "connectivity issues." Thanks for your responses. Speakers do look like the ones posted. They have huge open-sided rectangular alnico magnets, and are very heavy, c. 8-10# each. Labels say "Sunn Guitar Transducer,1216G", 60w rms, model # 81-0008. Baskets appear to be stainless or polished aluminum. Couldn't find any codes on speaker baskets, is it possible a generic basket could have been used if/when speakers were reconed? Guy I bought them from said they originally came out of a Sunn 2x12 cab, but he didn't know the model name/number. Haven't had a chance to hook them up as my amp head is in the shop (fried the power tranny due to out of spec resistors on tube grids and phase inverter circuit, along with a bad fuse, Yow!$$$). Anyway, if anyone knows anything about these speakers, who made'em, year of production, tonal characteristics, durability, 4x12 pairing suggestions,and type(s) of cab they may have come out of please let me know. Thanks...O.
