While I am an avid fan of the Bose L1 and use it on every job, I know what WRONG is talking about. I don't think I will ever go back to a conventional system (but will not say NEVER), however, I have added a mixer into the chain. Not only does it give me additional inputs that I need occasionally, but it provides more control of EQ and FX on individual channels.
Between the internal EQ settings in the keyboard, the Bose EQ settings on the remote and the EQ on the mixer, it is just a matter of finding the right recipe...at least for me.
As for a bass line that will part your hair on the dance floor, the Bose is not the gear to do that. The sub is fine, but IMO, it is a "warmer, more rounded" tone than you will find in some of the conventional gear that rockers and a lot of country bands use.
Again, my opinion, but two subs doesn't seem to do much more than one in an OMB situation.
Several rooms I play are wider than they are long, a couple other rooms are L shaped. No 2-speaker conventional system can come close to providing the dispersion necessary to cover the entire room.
