Andre, welcome to Axiom, and Happy New Year! My suggestion would be to set all your speakers to "Small"(I assume that you mean that the center is a VP150)with a 80Hz crossover between them and the sub. The frequency control on the back of the PSW125 should be turned all the way up, to get it out of the way of the 80Hz crossover that the AVR-130 is doing.

Enjoy the music, not the equipment.
