The media room was designed from a performance perspective and has exposed cables for easy change out. This allows me to easily experience different cables and power products. After more than a year of construction, my media room is nearly finished. A few more trim pieces and the project will be complete.
Interesting features:
Dimensions for the room were calculated using the RPG Room Sizer software program. The sound waves see a room that is 9'H by 24'W by 30' 1/2" L.
The false side and front walls are designed to allow the low frequencies to hit the concrete foundation. There is enough mass in the foundation and floor to keep the low frequencies in the room. This results in a deep extension of the bass frequencies. The false walls, built about one foot from the foundation, utilize modified RPG Acoustic treatment panels designed to diffuse and absorb the upper bass to the high frequencies. The bass frequencies pass through the acoustic panels.
Two layers of 1/2 inch plywood were used for the ceiling and back walls (4,000 lbs). Plywood was chosen because of its high tensile strength. The first layer was screwed and glued with construction adhesive to the joists and studs. Visco-elastic glue was coated on the first layer and on the inside of the second layer so that the glue was sandwiched between the two layers of plywood. The second layer of plywood was then put up and screwed every six inches. (Over fifty pounds of screws) The result is a very rigid ceiling and back wall that has very little, if any resonance. The visco-elastic glue acts as a sound barrier that keeps ambient sound from entering the room. The other benefit is very little sound emanates from the room resulting in excellent sound pressure levels.
A dedicated electrical panel was installed for the media room. The wiring is 12 AWG except for the equipment rack, projector and amp outlets. These outlets use 10 AWG. HVAC vent was dampened to reduce sound from the furnace and air conditioner.
A diffractal is on the back wall using Auralex T-Fusors. It is designed to break up the sound waves that bounce off the back wall. Reflected sound waves do not interfere with the sound output of the speakers. Four inch crown molding was installed to diffuse the sound waves and to prevent them from creating a megaphone affect at room corners.
Behind the equipment rack, a door was installed to make easy access to the back of the equipment. Changing cables is easy because the equipment closet is well lit and has access from the front and rear.
An anamorphic lens on the projector allowed for a very large screen (198" diagonal) The Home Theater Screen is DIY. It is made of 1/2 plywood with luan painted (six coats)and glued to the surface of the plywood. After each coat of paint the surface was sanded with very fine sand paper. The final coat was applied using a 1/4 inch nap roller.
