Ideal 2-channel listening room-Acoustics Forum-Acoustic Fields Forum

Hi Mark, Matching room size/volume to usage is a balancing act between many variables. You need to go large enough in both size and volume to minimize low frequency issues below 100 Hz. Treating frequency issues above 100 Hz requires different absorption technologies than below 100 Hz. Absorption treatment below 100 Hz. is 4-5 times more expensive. The goal is to be large enough for your usage, that you minimize the amount and surface area that you will need to treat the low frequency unwanted pressure issues. We use 19′ w x 11′ h x 27′ l as a minimum for two channel listening.

All treatment can be made to be freestanding or wall hanging. This allows for you to take your acoustic treatment with you when you move. It is just as important as your amps and speakers. Save the boxes.

We like diffusion on front and rear walls with absorption on sides for image definition, staging, and focus. Once we get those three, we can then diffuse the defined and focused energy using front and rear wall diffusion. Ceiling treatment can be either diffusion or absorption or a combination of both depending on usage and ceiling height.

Low frequency management 15,000 . I would estimate 10,000 / front and rear wall diffusion . Another 5,000 for side wall foam and 10,000 for ceiling treatment. If you build it yourself, you can reduce costs by 40 – 50%.
