Remember when I sent you my PEQ setting for my Elite R-55e tower's. When Shady J reviewed and ran test on those RBH Elite towers, he did state they are a little forward in the mid range, test even showed about a 4-6 bump around the 1k and up to about the 3k range, right around where vocals would be. Anyways without make my reply to long, EQ can work when applied correctly. Also with the proper room treatments.
Other then replacing the speakers maybe wrapped some blankets around them so they'll warm up some.
Just kidding.
