So.. I'm thinking out loud about possibly running a bi-amp setup. I know a guy in town who builds PAs and enclosures.. So I was considering running a 15" or 18" sub w/some mid drivers and using 6"s instead of a tweeter (I hate the sound of tweeters). He will probably be able to work out putting all of this in a single enclosure.. Similar to an ampeg i've seen a while back that looked a lot like this.. So.. What are your guys' comments? I'm currently running through a 410, and if i'm on a big stage, it sounds amazing, but if i'm not at least 15 feet away, The thing only hits me at the knees with sound and it's hard to hear myself as well.. Thoughts?
