Tony, Keyboards are to heavy for this old Guy I just use the pa800 to create some of my tracks. Also the footprint of this setup is very compact ideal for my sort of gig's. I can be tucked in any small corner.

Donny, I already had the speakers so this was just a better way of utilising them. Bose to expensive for one or two gigs a month and as I mentioned the flexibility is very handy. It's a question of Horse's for course's.

Mirza, no choice, the cross over is set by the manufacturer (Kustom or Powerworks) although 150hz seems fairly common for a sub. BTW Lots of folk seem to think a Bass Amp shouldn't be used as a sub but it works for me.
