I have a friend who uses one of those Bose things (I think it was L1 model 1 but not sure). He needed 2 subwoofers to fill a medium sized dancing crowd room.
In a little over 2 years it broke, and was told Bose doesn't make the parts to fix it anymore. It's a doorstop.
He went conventional and bought our old Carvin powered speakers. (We bought new EV powered speakers about a year ago so the old ones where just sitting around.)
I have no idea if this it typical or not, but if you are using the Bose, I suggest you get a spare for a back up.
That advice actually goes for anything. I have a power amp and non-powered speakers that I use in my studio that were once in my PA system that can be called back into action.
