I have 1.6s sw-1 sub, I had it downstairs, rec room, concrete floor with full rug, 18x22 great sound with minumal fuss. I than moved everthing upstairs to an area, country kitchen and small rec.16x28 hardwood floors, lots of windows and blinds etc. What a dissapointment, terms like harsh, fatigue disorentated sound, fitted right in. I stayed with it using placement, some sound absorbing, etc, and now have fairly great sound. Crazy business this high end. Jerry G
