Cool, I enjoyed watching the series on your dedicated space. Couple of questions, these may be answered in Part 4, you did not mention any acoustical treatments...are you acoustically treating the area behind the screen with absorption? Also a mixture of absorption and diffusion to treat and control the main theater room? It really pains me to see other dedicated builds and they not they do not add any acoustical treatments to reduce echos and bring rooms reverberation time down. EDIT: I just scrolled down and see some videos on home built absorption panels so I guess you did.....
