I do not currently use specifically-designed room treatment products. The A/V setups in the living room and master bedroom are full of furniture, curtains, paintings, bookshelves, etc. There is really no room for treatments.
However, once my youngest daughter moves out to go to college, I'll remodel her old room into a combo office/home theater configuration. At that point room treatment products become much more viable.
What kind of products would I consider? Assuming they provide acceptable sound management capabilities, they would need to meet the WAF for a multi-use room: attractive, unobtrusive, available with different fabric or paint choices, etc.
Thanks, Rick
