Hi Spalding
Avoid the Sound-bar, as like the speakers designed for the Tyros keyboards, it sucks, big time.
I disagree! The sound bar sounds AWESOME. It's seriously better than any on board speaker system I even used, and I've used most of them. The only drawback I had with the PAAS was the fact that Korg hard wired it to the output of the instrument only, and it will NOT let you monitor any audio you feed INTO the keyboard through the aux ins. That was a deal breaker for me. For sound quality, volume and punch - it's GREAT.
