Just off the top of my head. In a room that small, I'd put the speakers (I assume they are on the computer desk) on the narrow end of the room, where the window, bed, and storage shelf are now. Center the speakers on that wall, and have them fire into the long part of the room. Space them wide enough so that they form an equilateral triangle with your head when you are sitting in the mix position. I'd add as much bass trapping as possible, there are many ways to accomplish this that don't involve permanent construction. I'd create a reflection-free zone at the mix position. That'd be a very good start. From there, you can add more bass trapping (you'll need it), absorption on the rear wall (opposite where the speakers are) and possibly a moveable gobo or three if you will be recording with microphones in the room. Look into rigid fiberglass, mineral wool, and/or acoustical cotton for your acoustic treatments. I'm assuming you want to make it sound better inside the room, and that isolating the room from the outside isn't a concern.

Hi Luke, your best bet is to go read up on acoustics. One fantastic place to start is Ethan Winer's Acoustics FAQ. Most of your questions are answered there. It's a lot of information, but spend some time with it and you'll really understand what you need to do. Blankets are almost, but not quite, completely useless in terms of bass trapping. What you need is a material that will absorb sound well into the bass register, placed in a way that maximizes low-end absorption. There are commercial bass traps available that perform very well, if you have the budget. If you are a DIY kind of guy, most people use rigid fiberglass panels like Owens Corning 703, but you can also use mineral wool (rockwool), and acoustical cotton that come in 2'x4' panels in a variety of thicknesses. These types of materials are not available at most Home Despots or Lowes, but you can find them. Rockwool is generally cheaper than fiberglass, and performs very similarly. I'm assuming that you don't want to do massive construction in the room since it is also your bedroom, so what I would do is buy a bunch of those panels (realtraps, or make your own), and stack them together so that you have 4" thick panels straddling the corners of your room: both wall/wall corners and wall/ceiling corners (or even wall/floor corners if they aren't in the way). These DIY panels will need to be covered with some sort of fabric, and possibly framed with lumber if you are so inclined. You can also use these as side and rear absorbers to create the RFZ. These panels don't need to be as thick, 2" will work and you could probably even get away with 1". Space them out from the wall, the same distance as the panels are thick. What you want to do here is sit in your mix position and have a friend take a mirror and run it along the walls. Anywhere you can see the reflection of your speakers in the mirror from the mix position, put an absorber there. A moveable gobo would be something like a wood 2x4 frame with plywood on one side, full of acoustic panels and covered with fabric on the other side. That way, one side will absorb sound and the other will reflect sound. Then you can arrange these free-standing panels around whatever you are recording with a microphone to get the best sound. You can also kill 2 birds with one stone and use these gobos as your side or rear absorbers for your RFZ: when recording, arrange them around the performer, when mixing, arrange them on the side/rear walls. If you don't want to do any of this, or if you aren't up for learning about acoustics, and if you have some sort of a budget, then the easiest way by far to get good sound out of an ordinary room in a house is probably to stock up on Ethan's Realtraps. But, go read the acoustics FAQ. Then follow up with more questions. I'm sure someone more knowledgeable than I will answer.

Aloha and welcome to the forum, Luke! Congrats on your studio build! Any chance you could please:

Edit your profile to include your location. This is very important, because this is a worldwide resource, and as such, material costs and availability vary widely. For example, masonry is cheaper than gypsum in some parts of the globe, whereas it's the exact opposite in other regions.

This will really come in handy two or three posts down the road. It's also part of the forum guidelines: http://www.johnlsayers.com/phpBB2/viewtopic.php?t=3231 Thanks!
