Had the 108, went to a k10.2, both of these were used with a ASC-12 for shots and giggles in stereo, big fan of qsc .2 series. Had a couple of 12.2s for mains around 2017. The k10.2 was decent but has some kind of thermal shut down that is overly sensitive and maybe even defective. It shut down and had to reboot and " checking for blown amp" it was returned and never to be considered again. This is some kind of update from qsc, which has probably been fixed and qsc has an outstanding warranty and CS. However, I have zero interest in gambling on some frfr reset at a gig or even practice at home. The 108 sounds good, the challenge with it for me was , when you start getting it up to stage volume it's a 8" speaker which is almost studio monitor size. It's not 2000 watts no matter what spec sheet you want to consider. It sounds great with the axe no question. The k10.2 is very versatile and its cost and sound are more directed at mass applications and not modelers.. does not make it a bad option, does it sound better than a 108? For 3 times the price it better. Seems a tad un resourceful to buy a pa main for bands or a DJ and use it as a guita speaker. However , if you want to blast your music thru it and use it as frfr for fractal maybe a great choice. For my money 700 + tax = something that doesn't accompany shutting off unless its being pushed so hard its vibrating my windows at least.The k.12 pair Inowned performed flawlessly as mains for a band for several gigs, these were purchased before the update that accompanies the newer .2 series. It may have been removed on newer models
