I have a second room system that I am building. The room is completely enclosed and is only 16' x 11' x 9'. I can put the sub or subs in a corner to achieve some corner loading. I am most interested in the CS Ultra as I think it is a perfect solution in this case. That said I wonder if I could get away with using only one in such a smallish room. 90% of the usage for this system will be video. The family (that is who will be mostly using this system) is not nearly as bass happy as I am (have a BDEAP-32 and a Crown K2 in the main system). I am having Jim Salk build me a set of Veracity 1 speakers with a Veracity CC up front and he is building me a pair of sealed Ellis 1801's for the rears. Any thoughts regarding one CS Ultra vs two in this set up??
