I love the Vandy 2Wqs also, and I own a pair. However, your mains must be fairly flat to 40Hz to work with this model. I am not sure that is the case with the Arros. You risk having a dip in the response between 40 and 80Hz.
As an alternative, you could use Vandersteen's V2W sub. Also, my brother has a HT system using Totems (either Arrows or Hawks, not sure), and he has a pair of the James subs (the smallest model with 10" drivers). Seems to be a nice pairing.
