If you don't need the last few dB of headroom maybe get the KRK.
I love Kali's sound but have had so many manufacturing faults / DOA units / electronics failures it's kinda ridiculous. I'd say I've probably bought about 14 Kali speakers and at least 5 have issues.
Specifically for the WS-12, one of the five units I've owned died totally just after the warranty expired, and it had a fairly easy life until then. Another one which I still use, a v1, occasionally emits loud crackle after the soft start. It also gets passed to the HPF output; power cycling clears it. Another WS12 I have sometimes hisses. That said, the only v2 WS12 I have has been rock solid, so far. So that's 3 out 5 with problems... They are meaty things for the money though, so there is that. And maybe V2 is better..?
