Hello SutterCane,
Hope you are well. I have not heard either the VP100 or the VP150, but neither one will allow a smooth 80Hz crossover, you will need to run a 100Hz crossover.
Frequency response for the VP100 is 95Hz to 22kHz +/-3db, and the VP150 is 85Hz to 22kHz +/-3db. This is the reason I chose two M2s for my center channel since they have a 70Hz to 22kHz +/-3db frequency response, which allows a very easy 80Hz crossover. Looking at the NRC data for the M2 shows that at 80Hz they are at 87db 1watt/1meter at 80Hz. If Axiom would develop a ported center channel design then this would be moot.
Later,
TonyM
