Cloverdale Cinema Build
I’m in the process of renovating my house and am planning to turn my basement rec room into a dedicated home theatre room. I used an acoustical calculator to figure out the optimal dimensions based on my anticipated ceiling height (8’) and the output was room dimensions of approximately 12’8” x 18’6”. My rec room is about ~13’ wide by ~19’ long - pretty close!
The theatre will be in the basement of a two level house. The kitchen is directly above. Two side walls will be exterior, another shared with a guest room and the fourth shared with a mud room. Everything is gutted at the moment. Ive attached our house layout.
A key item for me is to incorporate effective sound transfer control mitigation measures into the design. I have 2 subs (SVS PB 2000s) and intend on having 4 sub eventually (want to build two "Martys") - I like deep bass...
Based on my research, the soundproofing plan for the HT room and the adjacent guest room is to use Safe n Sound insulation within the joist bays covered by 5/8” plywood (for anchoring purposes) then resilient channel (type to be determined) holding two layers of 5/8” drywall adhered using green glue. I am also going to install a sound “kill box” in the HVAC runs into the theatre. Only one window (will install a window block). There will be a small room between the main house and the HT room area that will assist with managing sound leakage past the main HT door. Both doord will be fully sealed. Lighting will be via wall sconces. Nothing through the ceiling except the projector outlet and cable throughport (need to think this one through).
Any thoughts on other considerations related to managing sound transfer? Should this be sufficient to hold back most of the bass noise?
#2 Speaker layout.
I have a Yamaha 2070 w 9 channels. I currently have a 5.2.2 speaker system that could be 7.2.0 (my two ATMOS speakers (SVS Prime Elevations) could be used as rear surrounds).
I can add two more speakers to my system, so in the absence of buying another amp to power a 7.2.4 system (optimal), what do you suggest is better for an immersive surround sound experience, 5.2.4 or 7.2.2?
There are so many different speaker layouts with F or R presence speakers, overheads etc. I’m in a bit of analysis-paralysis on layout at the moment as it relates to where I run speaker wire. I don’t want to regret anything once the drywall goes on!
#3 Location of Components
It seems that most HT rooms that I see online have their components outside of the room or at the back. I have had mine at the front, as it seems to make sense for line of sight control, being able to observe active audio codecs, volume etc on the AVR. Also, I have little kids and the low component shelf helps keep dirty hands off of the very expensive fixed projector screen!
Anything I missing here that should compel me to relocate my components to the back? A back corner would take out a logical subwoofer spot. Need to run all my cables now!
Suggestions would be much appreciated!
