Outside of subwoofers (where the changes were pretty dramatic between versions) the changes between earlier versions were more incremental as I understand it, and Axiom bumped the version number when enough changes had accumulated across the product line.

My home theater system is still all Ti speakers (except for the VP180 that replaced my old VP100) and those are still hard to beat for home theater use. Most of the refinement over the years is more applicable to music reproduction than HT in my opinion.
