I'd actually settled on Yamaha DZR 12's back in June but after waiting 3 months for the Canadian distributor to fill the order then being told speakers wouldn't arrive until the new year, I had to go looking for something else. Here's a very condensed pro/con list of powered speakers that I'd compiled to come to my decision.
I was in the same boat waiting on a set of 315s, I told the dealer I would think about it and a week and a half later they magically showed up.
No sure what is going on with Yamaha, but stuff does seem to be trickling off the boat.
