The Bose subs were clipping when pushed with the V-Drums. I don't think adding a couple more would really change that. And we already had the big JBL sub and that has no problem.
The first night we used the Bose system the singer was pretty jazzed about using them behind us on stage. It seemed like it would work well except having vocals at a level needed to get above a live rock band added to our onstage mix made it much harder than normal to hear the other instruments. Of all people to complain about the extra volume of the vocals onstage the drummer was adamant that we use the Bose towers in front of the stage and continue to use conventional monitor speakers.
One thing we did try was to mix in a little of all the instruments which the L1 handled wonderfully, but we still decided to move the towers out in front. But I was very impressed how easily the system handled vocals, drums plus electric guitars and some keyboard and still sounded great. Maybe in the future we will experiment with that again though.
But in a non-rock lineup I think the Bose towers would work great as monitors as well. Now we aren't at all loud compared to most rock bands but even still when we were using the towers as monitors we did tend to have a few feedback problems.
Everyone in the band has only had good things to say about the system. And people who have seen the band on previous occasions are enjoying the comfortable clarity that the Bose delivers.
