I have 3 original QSC K10s (with gig bags) that I keep in the rare occasion I work either band or a mobile DJ job. I'm thinking to put them up for $1800 for all three speakers then, turn around and buy a pair of QSC K12.2 ($2k). BTW, I have a pair of Alto TS312s that are mounted at the venue. Might end up changing out the Altos for the QSCs, but I haven't decided. I'm wondering if any of you guys might have any suggestions that might be better than the QSCs? I do like the newer line array (bi-amp) systems but I'd have to cough up another $1k-$1.5k out of pocket (things are pretty tight right now and I don't have many gigs lined up for this year). Your thoughts?
