Luis, I had the opportunity to audition the Bose PAS thru my Yamaha Tyros on several different occasions (both in a studio setting as well as on a gig), and even after attempting to tweak the EQ settings on the PAS, the Yamaha Tyros stereo samples (especially the Stereo Grand Piano) sound terrible : very thin & tinny. The problem boils down to the simple FACT that mixing a stereo sample (which also incorporates effects) down to mono results in phase cancellation and unacceptably poor sound because the effects are missing in the process. If you can afford purchase TWO (not just one) Bose PAS speaker ( $4,000 )then I'm sure the Bose will sound impressive, but ...



If you're wanting to use a single Bose PAS unit ($2,000) to play a Yamaha arranger thru, I say (to quote the phrase DNJ likes to use: ForgetaboutIt! The EV SxA360 is the CLEAR WINNER!: smooth response from top to bottom with a solid bass which can easily hold its own, and you get TWO speakers for the price of a single Bose PAS unit. I look forward to the day I too will be able to upgrade to the EV SxA360's, as in my comparison tests, heard a big improvement in sound between it and my EV SxA100's as well, and well worth the sharp price difference as well. To top off this, the EV SxA360's are lighter, and even more ergonomic to transport than the SxA100's (or other current comparably sized PA speaker competition (Barbetta, JBLs, Mackies, etc) as well. I guess you all know now that I'm really sold on power output & sound quality of the SxA360's.
