i have recently decided to install some 600w speakers in an old Sunn 215 after taking the original speakers to replace the speakers in a Kustom 215 (one of the speakers burst into flames a while back, and upon inspection i determined the cab was actually wired in series, much to my surprise).
my question is: if i actually had enough power to really push the 1200w cabinet i'm creating, would the cabinet be able to handle it, structurally speaking? the Sunn 215(i think it's a 215S?) appears to be in very good condition for its age, but from what i can tell it was designed to handle 160w about 40 years ago.
also, is there anything out there i can SAFELY use to power this (presently i'm running a concert bass into a coliseum slave and it sounds pretty sweet) cabinet and my 1200w Aguilar 4x12 simultaneously?
