http://minneapolis.craigslist.org/msg/827931010.html Well its not THAT special I know....but a little unusual it being a yamaha .. not well known for bass cabs. I know the techies are about to tell me the horn tubes are too short for real deep low end --- but that thing still looks like a real room filler. Presumably 1970s? Love to find a shell of something like this dirt cheap and load it up with some monster drivers. I was thinking these looked rather nice - v loud and smooth response with integrated tweeter (like tannoys) http://www.hempacoustics.com/CO15V_-_Hemp_Spec_Sheet_ready.pdf ..but then found out they are 1200 bucks each or something!
