I've got 2 K212s. They do anything I want them to. Full, deep, tight, punchy, or boomy depending on my settings. But flat response is tight and full of mids. Ive never farted the speakers out once, and they are loud. Way louder than any band would ever want me playing at. They're also like half the price of the RS series, but they dont have tweeter control. I have the head with the high pass filter on it (tweeter tone) so it doesnt really bother me, but before that showed up, there was no way to control the highs. The RS has the tweeter switch, and from what I heard, are alot better. But, I can't imagine much being better than the cabs I've got. Plus, they just look soooo good. Amps is another story and opinion, but I love what I'm getting from my BH500.
