dunno if this helps, but i had a bit of a listen to one when i was last at the music store i deal with, and i must admit to thinking the speaker system sounded quite good and "ballsy" especailly for built-ins....prob a bit better that the PA1x speakers, mind you the speakers with the tyros 2 that was also on display also sounded alright,(albeit with a powered sub running with it)..its always hard to quantify an opinion on sounds via text isnt it??
