Another reason & I have a few, I didn't like using the Both Bose systems I had is that I perform at many big venues with 300-400 people many times "without a stage" so I'm setup at ground level,.... the shortness of Both Bose poles isn't "high enough" versus my powered speakers being on high Poles to cover the back of the room as the sound gets LOST within the absorption of the crowds. I use to get many complaints that people in the back couldn't hear as well. lets face it the Bose is a very expensive sound system in mono & double the expense in stereo or even more with extra subs, ......some people like it, ....and some don't, no big deal, it's not a "cure all" for every musicians needs, versus so many other great PA Systems on the market.
Don't use the hype....use your ears!
