I do not own Quatros...have had other Vandy products in the past.
One item that Stang500hpaol did not mention is the minimum distance you must be from the drives for them to integrate (something that is required of 1st order crossover designs). I am not sure of the distance on the Quatros, but the 3A Sigs require 8 feet.
Others may have more knowledge...you could also check Vandersteens FAQs on their web site
