This current Media Room is the result of three previous media rooms and quite a few years of planning, growth and tweaking :-) I still have a way to go and have several upgrades/tweaks planned for the upcoming months.
I wanted a room that would serve for both music listening and home theater and believe I’ve struck a good balance.
We moved into our current house six years ago. The Media room was custom built over the oversized two car garage and is 18.5' x 22.5' with 9.5' ceilings at the center. All four walls have about a thirty degree tilted in soffit area where the side and rear surrounds are mounted. The ATMOS speakers are ceiling mounted and the front speakers are freestanding.
I placed all front speakers on concrete slabs floating on rubber isolation feet to decouple the sound from the floor. For me, this resulted in a cleaner more transparent sound on the LCR.
The stairs and upstairs area are carpeted with whimsical theater themed wall to wall carpeting. Front wall is painted a gray that is almost black and the ceiling and other walls are a dark/medium gray.
I recently upgraded to 7.2.4 Dolby ATMOS surround sound and have four Polk CS-6 ceiling speakers about mid-way for first pair and toward the rear for the second pair.
The room features two levels of seating, recessed Vutec 2.35:1 Widescreen (120 inches by 56 inches... 136" diagonal).
Built-in niches have shelves for ample music and video media storage. Large, double 19” equipment racks (Middle Atlantic) house all of the audio/video equipment for the media room and all ethernet and cable/satellite distribution to the entire house are placed in the back of the same equipment closet. The Media Room is on it's own HVAC system and has two 20 amp and three 15 amp dedicated electrical circuits and a separate 15 amp lighting circuit.

Pre/TT Amps/OPPO/Rythmik Subs - Belden 19364 14 ga with Hi-Fi King 15 amp “Red Copper” connectors
Things I might have done differently (and will if there is a next time :-) 1. added one more dedicated 20 amp line (or two thirty amp lines and two twenty amp lines. 2. added two more dedicated 15 amp circuits at subwoofer locations
3. Media room on separate electrical box with whole-house surge protection 4. Built a deeper platform for the rear seating and pulled the rear seating away from the wall by another two feet or more. 5. Used spray-in (paper based) insulation in all walls 6. Double drywall the walls or consider using a heavier material (like Wonderboard) for one of the drywall layers 7. add star grounding scheme for the media room with confirmed external ground.
This system has brought me many hours of enjoyment and entertainment. It continues to satisfy and provide me many hours of joy and diversion. You should hear Pink Floyd's Welcome To The Machine in 5.1 on this system :-)
