The paint i used was Pascol interior Matt black on walls and ceilings.After adding the Martini Absorb and rerunning Audyssey the bass seemed to blend in to the mix way more, than having no absorption. I really felt the sub in the mix and it was way more warmer than before. I played a CD which a friend of mine made and noticed the difference. The vocals were clearer with no lost sound at all.Well that's how it felt. My room is a big room so the absorption made a huge difference to the sound rather than having it bounce of a rectangle room with hard surfaces all round.I put San Andreas movie in the panasonic and noticed that the sub was not overbearing and boomy. Sometimes when viewing a quiet scene you can have a subwoofer track still going through the sub and in a room where you have no absorption, it can have a slight boom in the sub even at low levels, but i got none of that boom.Quiet scenes were quiet and louder scenes were within a realistic volume.The whole room sounded much better and it was really noticeable.After having a dedicated building separate to the house for Home Theatre and music for 12 odd years it was noticeable after installing the panels.As far as the video goes for home theatre, well the darker the better especially helps with a bright projector for that eye candy pop on the screen. My image stands out at the same time i have nothing else to see to distract me from the movie. Hope this helps you.
