New QRX 212's are "around" $2000. So maybe a price for a good used set would be in the $3000 range.
So the SM80s will be "around" $3000 each? A single 12 inch coaxial in a SH box. There goes my thoughts of a $1200 dollar or so Danley speaker... I'm sure its a great speaker but for those not informed of the Danley concept/rep it may be a hard sell.

I want to point out that you may very well only need a pair of SM80 cabinets to perform the job of four of the QRX.
Ivan's point about the Danley products getting overlapped for narrower coverage patterns is one that should be emphasized-the first large system of the old TD1 cabinets I heard was at the King Biscuit Blues festival in Helena, Arkansas, by Mike Grimm of CSS Audio in Peoria(he still provides). Twelve per side, in a 3x4 configuration, firing into the the side of a grass covered levee next to the Mississippi River. About 15k lining this to listen, and I spent all weekend there, walking thru the crowd up to the top of the levee, side to side, many times for a lot of different artists on stage.
One of the coolest things I noted was the absence of degenerative comb filtering-where any two rows of speakers in the hang overlapped coverage, it only got a little louder.
Mike has since mentioned in conversation that the main stage could be covered by less without any problem, there's plenty of horsepower.
