currently looking at the ascends...i've already decided that i am buying ascends...its a matter of what...i've emailed with david a couple times already, but i'm still conflicted....this will be part of a 6.1 system...on one hand i think the 170s would be best for filler, but as the 6 in the 6.1, would it be more beneficial to have something thats a single speaker, or something thats dual like the 200? or does it not matter? i'm leaning more towards the 170s, but my roommate (who's going to help fund this venture), is making me wonder if we should go with the 200s...does/would having 2 woofers and tweeter be an improvement or should i stick with my feelings and do the 170s in the rear?
