I don’t have the K 12.2 but the K 8.2. I was looking into buying the RCF TT08-A – an 8 inch speaker $2,000 each, but a guy who owns both QSC K8.2 and the TT08A says the K8.2 is 80 % of what RCF can do. I never liked the 1st version of the QSC K series. Too harsh. The 2nd version seems to be a big improvement as many say in comparison with the 2nd version. Prostar Audio was a having an 18% sale just about across the board. So I purchased the K8.2. Solid sounds. I use it along with my Centerpoint Stereo Spacestation V3.
