Hey guys, Right now I have an SWR Workingman's 2004 head and 2x10 cab. I want to add a 1x15 and I was considering biamping. I was reading up on it and someone said that your amp has to allow biamping? I read the manual for the 2004 and it has no mention of biamping. Am I able to do this with my currant setup if I get a crossover?
