I Can Do That.
In early 2006 while tediously cranking out Fujitsu Plasma Theaters in copious amounts, one lazy Sabbath I sketched out the theater shown below. (Cine)
Nowhere near my radar was there any possibility of me doing any serious HT builds. This goes to show the power of visualization, because one year later we would be drafting Helene, which is very very similar to the sketch.
If you look at the original sketch I wanted to have a projection booth with the equipment racked underneath the projector.
Lo and behold see the attached Barco stand.
If I was doing a design from scratch I would use the Barco stand.
The similarity between the above image and cine (attached) is remarkable.
For your plan I would just copy the helene dimension proportions (to suit a 18 foot screen) and leave a 5 foot deep projection room behind.
Feel free to pm me with questions.
My gut feeling tells me that Barco will have a less expensive version of the DLP .98 chip projector. The NEW Christie digital 2000cm is a more competitive (15k less) unit with just 2kw. The compact chassis of the christie will work against it's stopping down potential. When you stop down the light pipe of these units the contrast increases. There are four things we are doing to these units to increase the contrast whilst holding the 2yr warranty.
The Barco chassis is much better engineered than the new christie, it is modular and a very powerful control architecture, they (Barco) are not going to engineer a smaller unit any time soon. I expect a watered down dp1500 to become available to compete with the christie.
They can limit the lamp to 2kw and it can then run on a 20 amp 120v single phase circuit. I am crossing my fingers a DP1200?? comes out soon, it is the ideal chassis for a Home Cinema projector. Also instead of having 65db of fan noise to cool down a 4kw lamp, it could be lowerd to 50 or so (just 2k cooling is needed).
