Hi Scott,

The mixer/amp in the Stagepas 300 weighs approximately 5 lb.

So the speakers weigh around 17.5 lb. each.

I've used the Stagepas 300 on many clinics, both with the Tyros2, and the PSR-3000...haven't used it on the S900 yet...it is a great system for small venues, and, best of all...it's stereo.

Although Yamaha rates it at 150 watts/side, my guess is that it more realistically puts out 100 watts/side...but that's still a terrific rating for a mixer/amp that is so light.

Ian
