I have a gk 700rb head which it claims 380watts at 4ohms I'm running 2 bse4x10hlf cabs now. One cab for each output. I'm thinking of trading one 4x10 cab for a 1x15 cab. Also will be running the 4x10 out of one output and the 1x15 out of the other output. Being the 1x15 cab is 8ohms will it work? I'm not to familar with the ohm thing. Will I get enough power to the 1x15 cab? I'm haveing a hard time finding a 4ohm cab. By the way the 1x15 cab is a nemesis how are these cabs? Thanks for your help.
