This is an interesting coincidence. A fellow musician literally just gave me his old Bose tower PA system because he'd replaced it with two QSC K12.2s (anyone getting it yet???)
I never told him that my K12.2 broke (and it's in the shop right now), so he has no idea about that. He made it very clear to me that the PA system isn't fully working, but he didn't specify exactly what's wrong with it. So I took it home, spent a half hour figuring out how to set it up, and there appears to be a short somewhere in the base that powers the speaker modules—the power comes on, but then goes off intermittently. It seems like the modules themselves and the accompanying subwoofer work fine, but the base that powers them doesn't work.
So, at this point, I have this enormous (partially broken) Bose tower PA (that honestly I have no space for lol), plus my K12.2 that's getting repaired. I have two options: I could take the Bose in ALSO to get fixed, or I can see if I can get a new powered base (hopes not up on that... I've already started to scour the internet and have found NOTHING). Either way, if I can get the Bose to work, that'd be awesome. Honestly though, with my K12.2 that's being fixed as I write this, it won't be the end of the world if I can't get the Bose to work. Regardless, it was very generous of him to give me his old gear (this isn't the first time he's done it), so I'll try to make the most out of it if possible.
I also have a working speaker that I'm borrowing from someone else while mine's getting fixed.
