Thanks. I'd like to get that anodized to match the lens. The sled is a rough prototype to test the idea and it works well. I just chose not to use it for moving the lens out of the light path unless I want to focus the projector or need to demo Scaling for a client. It was installed so that if I moved the lens, I could get it back into the same position every time.
So this is a home cinema because of the booth? I see the benefit for mounting the rears on that panel, not sure there would be less noise though as the W5000 has intake and exhaust at the front.
The top mount in the EQ rack does reduce some noise, not all. To make this into a "hush box" would require some lining of the inside (maybe foam) and the glass on the front.
The idea of the "false" back wall was to create an environment that more closely resembled a real cinema. Therefore the EQ rack should not be visible in the room. Things like eye lines to the screen were all worked out before any construction took place. I was lucky because I had the gear set up in another location, I could "experiment" there and not have to risk getting it wrong in the room. All 4 surrounds are just over seated ear height based on the rear row of seating. Their diffuse radiation pattern (combined with THX Cinema 2 processing) makes the sound field very enveloping.
When I designed the room, I worked the layout as the "actual room" (back wall to screen) plus extra depth for stage/screen (being AT) and the EQ Rack behind the back wall.
THX's 36 degree rule in a cinema is from screen edge to edge back to the centre seat of the back row. And they now have 45 degrees being their preferred seating distance. As it turns out, the BenQW5000's optics cause placement of the projector to be about 3.7x the image height, so when using the anamorphic lens, it works out about the same 36 degrees.
I elected to use two rows of seats where the front row is just past 2x the image height and the rear row is about 3.2x the image height. The room has reasonably good sound absorption (I think it needs some diffusion) and total light control. The room is also "decoupled" from the rest of the house and was constructed using rubberized adhesives - so it doesn't rattle - and doesn't leak sound as bad as it would if it were physically attached to the house.
Because I already had the screen, I designed the room around that so that it would deliver maximum impact and it sure does being wall to wall. If I was to build another room from scratch, I'd do the same, just on a larger scale.
The only issues I see with a booth is getting remotes to work from your seating position, (unless you use one of those IR sensors under your screen), space and cost. Otherwise it's a neat way of doing things.
IR Repeaters can work well. The only thing is sometimes I'd like to be able to see the screen on the AVR as my Pioneer does not display on screen like some Onkyo units can, so maybe that's my next brand of AVR.
