Alan,
I still use a Yamaha powered mixer, the 640, and JBL Eon speakers. This works fine for me. On smaller gigs I just carry in 1 speaker. I'm set up in a matter of minutes and teardown goes even quicker. I get a nice full bodied sound and I can play as soft or as loud as is called for. The Bose PAS does interest me. I have some Bose home products and the sound quality is impeccable.
Since you live in Australia, do you know Stefan? His website has intrigued me.
Salud,
Joe
