Building a Music Room

[jcmusic]

Hi Guys,
This is my first post here so please try and help me out!!! I am getting ready to build a dedicated 2 channel listening room and want some advice on the acoustics. The room will be 19.5X13X8 with one stndard size window and one door. I am curious about the ceiling can I use something on top of the sheetrock? Any and all adivce will be appreciated!!! Oh yea!!! the speakers will be on the short wall, they are Klipsch corner horns with SET power!!!

Hi Jay - welcome

The cavity above the drywall in the ceiling should be insulated. While that won't damp anything in the room, it will allow the sheetrock and cavity to provide a little midbass control and stop it from ringing like a drum.

Where is the door and window in relation to the length and width of the room?

Hi Bryan,
Thanks for replying, the window will more than likely be on the one of the long walls, and the door on the rear wall. Thanks for your help.

Can you be a little more specific? Middle of the walls? Toward the corners? Try to keep them away from front corners of the room and the window away from your reflection points.

In general, you'll want some broadband bass control in the front corners and reflection panels on the sides at a minimum. Depending on speaker type and location to the boundaries, etc. nothing, absorption, or diffusion behind the speakers may be in order.

Rear wall - again, depends on how everything else falls whether you'll need bass control in the middle of that to deal with bass nulls.

Diffusion on the rear half of the side walls is always a nice thing if budget will allow.

Bryan,
In my first post I say there that my speakers are Klipsch Conrner horns, so that covers the front corners. I am thinking mid-way to toward the rear for the bookcases.

Sorry about that. With Khorns in the front, you'll want some absorption middle of the front wall and at the side wall reflections. Broadband bass control in the rear corners.

With an 8' ceiling, you'll likely also want something relatively thick directly over the listening position.

Ok Bryan,
I am thinking about setting up my gear as it is in it's current room, that would put the equipment rack in the center between the speakers. Is this going to create problems?

Jay

If you can use a low, wide rack, it should be OK. That's always a good idea anyway no matter where it is just to keep it below the listening axis.

Ok Bryan,
Now one more thing, what type of materials should I use in the construction of the room? Anything really a must? Or can I just use standard building materials and then treat the room?

It all depends on how far you want to go in terms of isolation.

For the ultimate - Room in a room with walls decoupled with DC-04 clips, either floating joists or RSIC-1 with hat channel on the ceiling. Double drywall with Green Glue. All HVAC isolated. All outlets and switches and lights boxed around. Float a floor. Make sure you use a solid core wood door.

Something like that will give you an EXTREMELY low noise floor in the room allowing for excellent dynamic range possibilities, and the ability to hear way down into the details once the room is properly treated.
