Dude, couldn't agree more about the 360/361! It took me a while to hunt one down in great working order....only to have UPS do a number on the power amp in the cabinet when they DROPPED it from their truck. But, oh man....how that low end is thrown so far is astonishing. The difference between standing 10 ft. in front of it, and 50 ft. is incredible. And hard to describe unless you've experienced it. Here's a pic of mine...which rarely leaves the apartment anymore (living in NYC without a car, and being 50 makes for a bad combination)
(And you're right, the 301 cabinet isn't really bad at all to move about. Especially w the two wheels and recessed handles, and only one speaker)
