ProAcs work very well with the vandersteen 2Wq. It helps to free them from much of the driver excursion they are now doing when trying to make deep bass (below 80hz) and the air pressure and resonance that comes along with that deep bass. They will sound faster, clearer, smoother and more effortless once the 2Wq & crossover are inserted into the system. Of course the bass will be much more extended and powerful with the sub in the system.
