Which Vandersteen sub, and how old? There have been so many advances in powered sub technology that--if the Vandy lacks certain features--it may hold you back from putting together a good sat/sub system.
At the risk of being impertinent, why are you ditching panels in the first place? Have you heard the X.7 generation of Magnepans? I can't believe how stupid good my new 1.7s are for $2K, and the 3.7's (and upcoming 3.7i's) are reputed to be that much better.
A sat/sub system that really caught my attention (and held it throughout the demo) was a pair of B&W PM1s mated to their PV1D subwoofer. They used Classe electronics which high-passed the signal to the PM1s, expanding their dynamic range.
