This first picture shows where the A/V and Computer racks are located. The A/V rack is where my MythTV Front End and AMPs will be located. The Computer rack is where my MythTV Backend and storage system will be located. I separate them like this because rack-mounted computers are loud
This picture also illustrates how I plan to cool the theater room. I plan for the room to have a dedicated thermostat that controls variable speed exhaust fans to skim the hot air off the ceiling and blow it into the adjacent room. Fresh/cool air will come into the room thru some passive vents sprinkled about the front
Finally, this picture shows how the Mech/Storage room will get vented. My county requires either a louver door or top/bottom vents - I plan to put top/bottom vents as far away from the Computer Rack as possible so as to reduce noice coming into the finished space (see green rectangle bottom-right of picture). I'll add sound treatments to the Mech/Storage room if necessary...
This next picture shows how the I-beams and ducts protrude into the theater space. The one duct that crosses near the screen is servicing upstairs vents and can not be removed. Note: the purple rectangles are suppose to represent vents...
In this last picture, you can see how I cover the I-beams and ducts with soffits (no, they won't be blue
) while leaving room for a raised star-field
I understand that the putting the PJ in the back like that restricts my selection some, but the "Find Projectors" feature on Projector Central indicates that some real winners can do it (like the Sony VPL-VW60)
I appreciate the feedback so far, but can anyone help answer my original question regarding if the wall-plan is sufficient to sound proof/isolate the room?
