Hi Wiggins,

Don't get carried away with room treatments before you hear your speakers. From the pictures of your setup, it appears there's a rug or carpet on the floor, which is excellent. You do NOT want to create a dead-sounding listening environment.

Adding sound-absorbing baffles to side walls may increase dialog intelligibility with home theater, but it will also reduce overall spaciousness and depth for music playback (because more reverberant energy is absorbed).

Regards,
Alan
