Hi Dennis.
I’m enjoying your videos on the youtube channel and have 2 questions.
I’m currently drawing the floorplan for a new house and could use your input on the diminsions for the home theater / 2 channel listening room ?
Better with entire cealing as drywood or entire cealing of absorption tiles?

W: 18.00 feet – Can be adjusted about 1.5 feet
L: 26.25 feet – Can be adjusted about 1.5 feet
H: 9.18 feet – Can’t be increased, but decreased to 8.2 feet.

The usage will be:
60% movies / games at 5.1 or 5.0 setup
40% 2 channel listening

low frequency drivers will include:
4 or 6 x 6,5″ (front floorstanders b&w 703 s2 or 702 s2)
2 x 6.5″ (center)
0-1 x 10″ (Sub Woofer, might skip)
2 x 5″ mid/bass (side speakers, standmounters)

M,

Your room unwanted pressure issues at 19.5 W x 9 H x 27.5 L: are all treatable with pressure levels around 85 – 90 dB without the sub. Is the ceiling really 9′? What is the distance from the floor to the roof boundary surface? Do not count drop ceilings. Low-frequency energy blasts through them. What is your budget for the project? Will you be building your own units?

D,

Double checked on the room ceiling, and found i had added a bit to much, it will be about 8.66 feet (2.64m). I’m not sure about roof boundary surface, still in early planning.

I won’t be building my own units, and i’m a bit limited when it comes to treatment options as the room will also be the living room and wife aint to fond for how treatment looks. At the moment i only have two options, and might be able to get some panels on the front wall as well.

a) No treatment
b) Entire ceiling in absorption tiles.

Budget will be around 6000 USD

M, You must treat the low-frequency issues first. You will need 160 square feet of broadband absorption from 30 – 6500 Hz. Treating the ceiling will only lower Rt-60 times by 20 %.
