As it happens 2yrs ago i did a gig with my band at a big garden party used my BTII for my bass and Dubster added to the keyboard players small pa for the rest of the band and sounded great. Afterwards my mate who is a reggae DJ was doing his thing with his cabs inside and outside the house, so i suggested using my cabs instead so we had the BTII outside and dubster inside and it sounded incredible, full, clean with lots of bottom end. i think two BTII's and a dubster would be a fantastic quality lightweight pa, Not that you'd really need a dubster with two BTII's but can' hurt.
