Larry,
The sub is heavy. It`s not very portable. It`s mainly for a studio setup or for home use. But its a great package for such a requirement. For portability, as Donny pointed out, the BA330 is great.
By the way, I enjoyed listening to your keyboard performances on you tube. Very accurate control and fast hands !! You must be enjoying the SA guitar selections in the S950.
