What Everyone here is forgetting or misinformed about is
The Vandersteen Sub 3 and 2WQ unloads the heaving lifting of the main amp
while lowering the modulation distortion of the main speakers dramatically improving the clarity and transparency of the whole system while doing it without any DSP-inducing. issues Personally I prefer this as a seamless solution with all these added benefits make it an easy choice for music's sake.
