Donny: I've actually set up my EV's as you've suggested, but it still doesn't provide the direct close up & personal stereo monitoring advantages that built in speakers (PSR2000/PSR9000) or spot monitor type speakers provide.

The Carvin PM5's claim to be a cut above other spot monitors, and to produce an impressive bottom end for it's 5-1/4" woofer size, which btw is BIGGER than the 'built into the kb speakers' such as the PSR9000 & PSR2000, and delivers a lot MORE power (50 watts per speaker) as well. The total weight of the Carvin PM5 and amp package is about the SAME as the Tyros speakers + subwoofer, yet should produce a lot more volume output and better overall sound. I'm still hoping someone with first hand experience with the Carvin PM5 or the Yamaha MS202II's will step forward to provide feedback. Otherwise, I may just try them out myself on a risk free purchase trial. - Scott
