When I bought my first set of Axiom speakers I found a VP180v3 in the seconds deal page at a good price and said why not. I really have not put any thought into the speaker since.

I wonder if I am missing out on anything really major? Would it be worth the cost to upgrade to the 180v4 or would the VP160v4 be just as good? Would I see a noticeable improvement or is it just throwing money at the wall for negligible benefit?
