I'm shortly going to be moving house, which means that I will be able to get my TAG gear and M+K's out of storage and back into action. However, my KEF PSW1000 sub, which is now the only original component of my first home cinema is now looking really out of its depth, so I've decided to go for a new one. Thanks to all the heaps of praise I've seen in this forum, I've decided that I will almost certainly go for an SVS PC+, but I'm just trying to work out which one to go for: the 16-46, or the 20-39. I know we've got a few 20-39 owners on the forum, but do we have any 16-46 users? Am I going to notice a massive difference in performance for $50, and is that extra 7 inches going to rack up the carriage costs? All feedback greatly appreciated, as always.
