PRX612M sounds better than K12, but I’ve read in some other threads about troubles with the PRX in terms of overheating issues because of the lack of a fan and problems on unstable A/C supply. I’ve tried many powered speakers available in the market, but I personally like Yamaha DSR or DXR lines in terms of sound and reliability. Those two lines were developed in collaboration with their sister company called NEXO, a SR touring speaker giant…You will be impressed with the sound and power they deliver.
