I am trying to decide which speakers I will use to setup a 5.1 system in my ceiling. I have found two deals that seem to be very good at vanns, but I can't decide which is better. First option is using the Sonance symphony 6.5" two-way for all five speakers (these do not have swiveling tweeters). Second option is to use Mirage I-6c (rear), I-8c (front), and I-6cst (center) (these do have aimable tweeters).
