My current setup is a GK MB210 with a 210MBE extension running under it. I just joined a funk band, where for the first time in my life, I'm actually being told things like "turn up!" and "we want to FEEL the bass!" and "go as loud as you want, I'll tell you if you've gone too far". So I've started to push the MB210 and 210MBE really hard. I love the definition and growl I get out of it, but it's coming up short in the "I want to FEEL the bass" department. I also have an MB2-500 head which I got as a backup when the power supply of my MB210 died in December at a gig. My thought: Run the MB210 + 210MBE as I always have. Then take the "spare" MB-500 head and run a 115MBE with it. Then I'd have 500 watts going to 410s and 350 watts going to 115 with the option of having 2 different eq settings (I guess that's called bi-amping, right?) Do you guys think this strategy will work? I mean, I never thought I'd see the day when 500 watts into 410s was going to be "not enough" for me. It was a relatively small room too, but was PACKED full of people which just served as sponges to absorb all my bass.
