You can often compensate for missing room treatments in other locations.
If that was the extent of your room treatment, get wall mounted and ceiling mounted panels. GIK makes some Art Panels that let you have anything you want printed on them.
Sound carpet
Hi,
Recently my wife replaced my beloved shag carpet in the living room with a thin one and sound became cold and noisy. When I return the old one sound is warm and quiet again.
Any solution you know of ? Any product exists that can be put under the carpet that is not too thick for She Who Must Be Obeyed to complain about ?
