We were talking last night about the mains. I guess we assumed that the TRx line would be the same as the older lines, just a bit lighter. Good to know that there is a difference. I also think that folded horn subs might be the way to go, as they seem to project further into the crowd and into the back of venues better than just say an 18" speaker in a box sub enclosure. I think that we're going to hold off buying an elaborate setup as there seem to be quite a few sound companies around the area...e.g., Manhattan, Topeka, Lincoln, NE.... I think that there is probably a market for a smaller scale operation, though, and that may be more towards what we're considering. I'm thinking maybe 4 CV Earthquake subs, and 4 TRx215's to start with. We already have a decent board and E.Q. rack, so we can concentrate mainly on just building our p.a. up from what we own now. One thing I do have to say about our p.a. system the way it is now, is that it is way reliable. We have yet to burn up any speakers, and aside from a few mic cables over the years, hasn't been a problem at all. We did melt a passive "crossover" but it was very low quality to begin with.
