I have done a lot of searches on this thread to try to get definitive answers to my concerns, but still feel the need to post!
I want to wrap my room in the equivalent of triple black velvet (double black in Australia). That means ceiling, some parts of the side walls and rear wall in velvet-wrapped panels, and most of the side walls in velvet curtains (because that's an easy way to cover some doors and cupboards).
I'm wondering how this will affect acoustics in the room. I do have an Anthem AV receiver, so can run some EQ. But would, say, acoustic panels at first reflection point still be a good idea, and if so, would they be OK behind the curtains? There are currently some panels on the rear wall (pic attached). Those outside diffuser panels, according to a flashlight test, throw way too much light back on to the screen. The rectangular peaks are quite reflective. So should I just get rid of those panels altogether, or just build a frame around them covered in velvet? The seats will be replaced with new black ones.
Secondly, I'd like to double check the best way to install velvet with regard to sheen. Is the idea, with the projector displaying something bright, to install the velvet so that I can't see sheen from the seating position? Presumably that means that if I stand at the screen looking back towards the seating position, I will see the sheen, meaning that some light will be reflecting back on to the screen. Which way is best?
Thanks for any tips.
