OK, here goes...I'm setting up my theater with an XG-110LC. I currently have the projector mounted on the ceiling using a unistrut mount. When I built the theater I had two 4" ducts installed above the projector's position; I figured I'd use one for an intake and one for an exhaust, and put a piece of rigid foam board in between the two to force the air to go around the projector. I'm using a 96" wide 16:9 Wilsonart screen. Main problem is that my ceiling is under 7 feet high, and while the projector does not impinge on headroom when everyone is seated, it does risk becoming a distraction to the person sitting on the riser behind it.

So here are my questions:

How much clearance do I need between the bottom of the projector and the inside of the hushbox (I have removed the lid)?
What do I sacrifice by using 1/4" plate glass instead of expensive port glass?
What's the thinnest sound-absorbent material and the thinnest box construction material I can get away with?
For forced ventilation, I figured I'd use the inline duct booster fans available at Home Depot; however, apparently the 4" ones aren't very powerful. I could use a reducer collar and run 6" fans instead, but I wonder if I would gain anything by putting 4" fans in both the intake and exhaust?


Thanks,

Steve

I would skip the glass and find another way to seal it.

Have you seen the hushbox page on Curt Palmes web site?

I had seen that article, but had forgotten about it. It does answer the question of how thin a material I can use (answer: pretty darn thin), but it doesn't answer the other questions; specifically, how much clearance is needed...
