I, like many, received the axiom holiday countdown promotion and it has me considering an upgrade. I have a modest 5.1 system in my main family / living area made up of a pair of on wall m22s and on wall vp100 for LCR, a pair of QS4s for surrounds, and a Klispch RW12D sub. These are all being driven by a Denon 2312CI reciever. We use the system for about 80% tv/movies and 20% music.

When I bought the system 2 years ago I contemplated going with the VP150 instead of the VP100. In the end I ended up going with the vp100 mostly do to cost but I'm wondering, given the deal I can get now, if I should update to the on-wall vp150. Right now my only option is an on wall speaker. Will I hear a noticeable difference between these two on wall speakers particularly with movie/tv dialog?

Most discussion I find on the vp150 is people suggesting going with the vp160 instead but that is a bookshelf variety that won't accommodate my needs. There isn't a ton of discussion on the on-wall vp150.

Thoughts?
