ProAc 1.5's add sub or trade up?

Before I bought the ProAc 1.5's I already had a Vandersteen 2wq sub in my system. All I can say is that I am very satisfied with the bass produced with this combo. I think a Vandy sub is a great foundation for almost any system. It is a music sub not a home theater one. The filter system from the Vandy sub will also lower the distortion in the mid woofer and lessen the load on your amp to. I would also like to note that if blended properly this sub never calls attention to itself. If you consider this sub make sure you talk to a dealer that knows what there talking about or call Vandersteen to insure that it is compatible with your system. Good Luck!

Thanks for all the info. I am using them in a HT set-up with a marantz sr-19 (might be some of the problem) bi-wired (shotgun) with Harmonic Tech melody speaker wire. I guess I should look at entire package before making any decision. Thanks again

Thanks - Purchased a proac sub a week ago. Thanks for all your suggestions and recommendations.
