Hi Andre,

Since you have curtains on one wall and a carpeted floor, as well as couches that I presume are upholstered (not leather), I suspect you do not need absorptive acoustic panels at all. You certainly don't want any panels near the QS surround speakers, and I generally do not recommend panels that absorb first reflections, as these may lessen the "spacious," open quality of the sound.

Regards,
Alan
