Nice classy setup. I made my acoustic panels. Nothing to it! You could pretty much cover them in a fabric of your choice as along as its nice and thin. I just used speaker grill cloth. But my HT is mostly black. You could make your panels different sizes, shapes, etc. so they don't even look like panels! They would work wonders in your room and you would wonder how you ever lived without them
Really nice job. Semper Fi , Devildog.
