My current system is $100 HTIB which I knew was crap when I got it, but I wanted something for a "start" when we finished the basement. The sub is NOT powered so is super crap. The center (and surrounds) are the same...small, single driver things not worth lining the cat box with. The only thing going for the system is the progressive scan DVD player and component video. So if both the sub and ctr are equally bad and I can only afford to replace one, I'm not sure which I'll go with. It turns out my sis-in-law has a sub she will give me a t-giving, so maybe I'll wait for that and see how it works out, and get the ctr with my new mains.
Thanks!
