Question re the beam gen 2 for everyone, I just picked one of these up and was going to mount it in a custom cabinet, I have an empty fireplace below the TV which I am going to build a cabinet in and am thinking I will make a slot kind of recess in it at the top for the beam to sit in. Just wondering if anyone has done this or knows if its a total no no regarding the sound. I would make the recess bigger than the sound bar by a reasonable amount I just don't know if its going to ruin the sound stage, I know the beam has no upwards firing speakers, thoughts ?
