Work has continued since my return on the Wiring, Riser, Soffits and some significant re-planning.
On the wiring the previous contractor put in conduits, good, He left them hanging inside the walls with just a pull wire poking through the triple thick walls, not so good. So some surgery was required to open the holes to fit the balanced line connectors and speaker wires. Then there was this surprise. After opening the wall the pull wire was locked in place. Then I fished around and found a few alternatives.

On the planning Vik wasn't real happy with the column locations and the fact that the side surrounds were ahead of the seating positions. Probably as a result of the door location and the assumption the door would swing in, banging on a column. Since the swing was changed we kicked around some ideas then got Shawn on the speaker phone and talked about our concept. We got his blessing so we are set to relocate the side columns and make them a bit skinnier.

On to the soffits. In a theater like this you can't just bang up some square soffits so we kicked around a number of ideas and settled on a plan with many curves.
Starting at the front I proposed two alternatives

A lot of guys round theire soffit over the screen out, Vik said take it in complementing the feel of the stage.
Screwed and glued up some blocking for a 5 1/4 inch tall soffit. the top and bottom boards match the curve the middle is just spacing with a place to run wires. The blue tape is where the lights will go.


Vik said the soffit needs to be strong because he intends to shake the house. I said I would build it strong enough to park a truck on it. Vik said is that thing going to come crashiing down on my head? so a little demonstration was in order.

4 inch construction screws into the channels.
