[quote=Killroy;58560944]I can offer some insights from the lessons learned from designing my RS3000 hushbox. They Projectors) both weigh about the same and are about the same size.
1) Yes, you should mount it to the ceiling via a mount pole to the joists or whatever way it can be mounted to ceiling (I had to put a 2x12 between two joists since the projector was directly between my two joists, I deep bolted the 2x12x30 to the two joists). Logic for that is that the hushbox then only has to be strong enough to support its own weight and not the projector AND the hushbox.
2) You do not need to actively cool the hushbox but you will need to create a method to actively remove as much hot air from the box as possible. You can use the theory that you want put more cold/cool air into the box than it gets sucked out. This being said, exhausting the hot back INTO the theater room will NOT be an option as it will not only warm up your room but the exhaust nosie will kinda defeat the purpose of having the box in the first place. If you can I would suggest exhausting the hot into an attic via an in-line fan and to an exterior exit point in the attic (do not exhaust directly into the attic). If you are not in a position to exhaust into an attic (basement, first floor, etc) then you need to find a way to exhaust into either your return air (not recommended since the return air system shuts off when the AC fans shut off) or to an exterior wall, or another room that you don't mind if it gets warm (may a laundry room). But that also brings up the fact that you need to actively bring cooler air into the box as the hot is being exhausted. Some will argue that the pressure being generated by the exhaust fan (in-line fan) would be enough to negatively pressure the cold air into the box but I would not takethat change with a $24k+ projector. You can find some very silent PC based fans that will not only keep the cool air intake quiet but will also suffice the fact that the JVCs need air to enter the rear of the projector for proper ventilation. Yes, this is not that easy.
3) Not many people are building them commercially but Draper is still actively designing, building, and selling them (https://www.draperinc.com/liftsmount...spx?detail=997
). If you can shell out the big bucks I would highly recommend them since the guy that actually designed them actually was nice enough to give me lots of pointers to build mine when I told him that their box was way out of my budget range. That alone was worth a recommendation if you can afford them. There are lots of OLD threads here where people show photos of their builds but you will have to deep search the forum. Not many design threads but the pictures should give you some ideas.
And about mine... it was my design that would work in my room so I don't think I can say it will work in yours. It is HUGE!!! It is heavy. But since it sits in the back of my 24-foot room I did not care and more improtantly, the Mrs. approved it.
I posted some pics of the unfinished (not painted, no port window, no wiring of all the goodies, etc) on post # 18 of this thread: https://www.avsforum.com/forum/24-di...ditioning.html
as always thanks for being a true gentleman and scholar. I really appreciate you taking the time to offer your insights and knowledge to fellow a fellow forum member.
