I've been playing a Hartke 5500 and 410xl, and in the new band I'm in, the sound guy has been loaning me a home made 15" cab to run under it. It really helps the sound on stage a ton! I don't expect to be able to or want to have to rely on borrowing this 1-15" cab forever, so I'm going to get my own...but I'm not very knowledgeable about power ratings. The 5500 is 500 watts and has 2 - 8 ohm speaker outs on it. The 115xl 1-15" cab has a power handling of 200 watts @ 8 ohms. Am I gonna push that too hard, or is the 410xl going to suck some of the 500 watts? I just don't know the mechanics of this stuff...can anyone give me some tips? Thanks!
