I am looking into purchasing either a VP100 or VP150 along with M3Tis. I am using a H/K AVR 320 (http://www0.shopping.com/xPR-Harman_Kardon_AVR_320). The room size I will be using is 12' x 20' with 8' ceilings. If I get the VP150 I will be really stretching my budget. I am considering getting the VP100 but am concerned I may be disapointed. I guess if I am I can always go for the VP150. Any input on this decision.

How far back from the speakers will you be sitting ? Will the speakers be along the 12' wall or the 20' wall ?

If you order from the Factory Outlet, you get 10% off. Also, if you order 5 or more speakers, you get another 5% off. Not sure you took this into consideration on your purchase?

I will also be getting 2 brackets which will give me 5% off (The center, two speakers and 2 wall brackets). The speakers will be along the 20' wall. I should be 12-15' away from the speakers no matter how I do it.

I suspect that with that room setup the VP150 might be a better choice.

Agreed. If you are going to be 12-15 feet away I would be thinking about VP150. If the speakers are along the 20 foot wall, a couple of feet into the room, and you are sitting 2-3 feet away from the back wall then you would only be ~7-8 feet from the speakers and the VP100 would be more than enough.
