I finally got the O.K. to find a small subwoofer for our surround system. I've been looking at the Parts Express' Dayton MKIII subwoofer kit with a lot of conviction, but then a friend suggested that I look at the Hsu sub, and I can get it for the same price ($349) as the MKIII. So, now I'm stymied. Both have 250W of power, and good response... the Hsu is a larger box (19x14x18) than the MKIII (14x14x14.5) which may make the decision for me, but what I'd really like is to hear from anyone that has experience with either one of these particular subs. Anyone, anyone....?
