Ellis Family Retirement HT: Go big or go home
We have just started to convert our 2 car garage to a dedicated home theater. The garage was already dry walled, and we started by ripping out the drywall on the walls, and ceiling to see what we have to work with. The garage is 23" long, 19' wide with a 8' ceiling. We have a door on the backside of the garage that leads out to our pond, a water heater, and furnace are in the wall right next to the door, and these need to be taken into consideration for the dimensions of the theater.We will be extending the front of the garage out 4' to enclose our front channel speakers (3 La Scalas (heavily modified) , 2 Heresy HIPs and 1 of 2 Danley DTS-10 subs).. The goal is to hit 115db @ 10hz with a low power amp. I am trying to cut down our electricity bill as much as possible so a friend of mine is building me a 10 channel "D" class chip amp that will put out no more than 30wpc... Since all my speakers are 100 db or greater efficiency I figure this should be more than enough power to listen at reference levels.The walls will be built as a double 2x4 wall with fiberglass insulation, OSB, and 1 layer of sheet rock with green glue. The ceiling will be 1 layer OSB, and 1 layer of sheet rock. Making the room as quiet as possible is a must as it is right below our Master Bedroom and I like to watch movies late at night.We will be running 12 gauge Monoprice cable for 22 channels (even though we will only be running 9-11 channels for now... We would like to be able to be prepared for 11 channels of height down the road if the formats continue to expand the number of channels). We are using Monoprice Redmere cables for all HDMI. The equipment rack location will be on the same wall as the Heater and water heater in a cubby hole we cut out and will have a fan to keep everything cool.Are the room dimensions good for a HT or could they be reduced in some areas to get a better setup?Attached are some drawings up so this setup will make more sense.

All the big horns are up front and the JBL 8340As are for the Side Surround and rear surround positions. I am thinking we might have to build out around the AC ducting and then do the double drywall , GG around it. I am also thinking a wide soffit around the whole viewing area of the room in which I could then put all my lighting and maybe put my speakers in also.I think if we needed to we could raise the rear platform up a few more inches but not by much as we are pushing 7' of clearance now without a soffit.Any suggestions? Is this easier to understand our problem?
