Nice looking room but that is about it. Once again, the designers are not qualified or are not able to sell a proper room set up.
Seating against a back wall is a just wrong acoustically. In wall sound systems, another acoustic compromise all in the name of appearace.
Sorry, this is a dedicated space and I see no reason why a "professional" would take acoustics so lightly. Anyone can make a good looking space. It is the true designer that takes everything into consideration and makes it work.
