Just saw this thread.
If anyone (particularly Wrong) is still reading this, can I ask why you didn't buy a Model 2 system?
I never had a Model 1, but many people (both on the Bose forums and other musicians forums) admit, and often proclaim whole heartedly, that the model 2 with the Mixer is far superior in both sound quality and yes, even dispersion range!
Wrong, go back to whatever you like (Yorkville, Mackie, Peavey, whatever) but not at least trying out a full model 2 system with the Bose Mixer is doing yourself a disservice.
For the record, you have to properly plug in whatever music source you're using and sum the result to mono properly - there are pitfalls and mistakes anyone can make regarding this.
We've used the system for 2 months now - every kind of venue (including outdoors) and every type of audience - young/old modern Dance crowds, old Dance crowds, recorded music (in breaks) just added a Boss GT-8 Guitar Mutli FX pedal for my wife's guitar, plugged straight into the Bose, and NEVER have we had such reactions by the crowds.
Even "old regulars" at many venues are coming up to us suddenly "noticing" us...
I wouldn't put any restriction on this system regarding Genre.
.....well maybe death Metal....
