no such thing as overkill, in my opinion. \:\) How big is your current room, and future room? What are your listening habits? If your just concerned about music listening, you may just go for the 60's or 80's. However, for HT and movies a sub is nice. You may want to consider the new 350v3 though if budget allows. Also, consider purchasing from Axioms factory outlet to save 10%.
