I have one of these cabinets I have basically restored and reinforced the front baffle. It is not loaded with speakers at the moment but I have: Early 70s Eminence alnico 15's with 2 inch vented aluminum coils and straight cones at 8 ohms each. Some Chinese heavy ceramic 15s with ribbed cones. EV15L's Peavey Black Widow and Scorpion 15's Stock Utah 15's that came in the cabinet but these have really loose suspension (bottom out)....I use these for guitar actually and they sound really good surprisingly! What do you folks say? Maybe I should make a guitar/bass all purpose cabinet. Are these cabinets any good for more of a vintage Bass sound say driven by my 1973 Carlsbro 60TC (think Hiwatt)?
