I have a 1212L that's going to be delivered today. I plan to use it on it's side with the angled speaker and tweeter on top.
did my first gig w/ new 1212L last night---used it in it's normal configuration, no stand--everyone, including myself, could hear the bass real well--looks a little funny being so compact, and you have to bend over to adjust the head (t-funk 420) but worked great. this was in a 125 person capacity room we've played numerous times before, and it was the best I've ever heard myself--absolutely no boom--just nice tight bass--guitarist on other side of the stage said he could hear every note clearly
