did anyone ever have a speaker that used twist locks get connected to 120v ?
I remember that "back in the day" :-)
I also remember the co that had that rig (big Martin "phillishave" and 215 piles of bins) had it all wired backwards so you couldn't plug the speakers into live power if there ever was by chance a matching twistlock near amp world. (I seem to recall they weren't normal 120V twistlocks either -something like an L2-20 for 2-pin or an L16-20 for 4-pin use)
I can image some of the new high-power subwoofer drivers available nowadays might not actually mind 120V line power :-)
