I'm looking at picking up one of the Crown XLS602s off of ebay. They seem like a pretty good value, and put out 1680 watts in bridged 4 ohm mono mode. My question is this: I've got 2 cabs right now, an Avatar 2x10 and an SWR Workingman 1x15. The SWR is going to be replaced with an Acme Low B2W soon. The XLS amps have only one output, a single Neutrik Speakon (there are binding posts also, but those are useless as far as I am concerned). How is it possible to run 2 cabs, making use of both channels, using this one output? Neither of my cabs have speakons, either. Is it possible to use an adapter of some kind to connect with?
