I am using a 450 watt Ampeg B2RE head. I am running it through an Ampeg 1x15 cabinet. It sounds good but just isn't loud enough with my very loud rock cover band. So I'm considering running it through a 4x10 hartke VX410 bass cabinet. From the experienced ears here... will the hartke sound that much worse 1) because it''s not an Ampeg, and 2) because it's 4 10's and not a 15 (for lows)? I can't tell much of a difference, just a bit more mids. But I'm onstage and not 100 feet away where the people hear it. Thanks!
