Ever since I "upgraded" from my m-audio bx5a's to the bx8a deluxe's I have thought they were wayy to harsh. as a result, I've made alot of my mixes lately very dull sounding. I didn't have this problem with the bx5a's. Could it be my room (which I admit is poorly treated, only with a pack of auralex foam), or is it the speakers which I now really don't like. They are ok if I cut the 3-5k range with a dip at 4k, but I feel like that's all guessing and it's going to make it worse in the end. would putting up 703 insulation help at all?
