Yamaha DTXpress/DTXplorer/DTXtreme

Keith thanks for all your help. I feel quite inept at this. I rarely ever post to forums asking for help —  a combination of common sense and "reading the manual" typically gets me to the right result. 

However, this thing has me stumped.  I just want to plug and play. ?!?!?!?!

There is actually a 5 band EQ on the speaker. Dropping the base does not seem to do anything significant. Plus, I get clipping on all drum hits, it's just more obvious with the bass. So, I don't think an EQ will be the solution.

The bottom line here is that if I drop all input signals low enough or drop the master volume enough to reduce clipping, I am not putting out much sound. It kind of defeats the purpose of buying the speakers in the first place. My goal was a simple ability to have a live monitor alternative to headphones, plus the ability to gig a bit with it. 

I'm not looking to blow out the walls, so 1000w is beyond what I had in mind in terms of power and $$.

This creates lots of high frequency harmonics which sound awful and blow up your tweeters.  With a bi-amped design that is less of a problem because the bass distortion cannot get to the tweeter.
