For a good few years now, I've gigged with a pair of 2 x10's and been perfectly happy. Lately I've felt the need to down size, so a couple of weeks back bought a Barefaced Big Baby 2 (1x12" + horn).
To date only played one gig with it, so early days but so far, I'm delighted. Certainly a game changer for me, no compromise on sound/volume, if anything more articulate. A huge plus for me, being the ease of load ins and outs.
