Down and dirty cheap room conversion
Hi,
I understand your question completeley - little cash, small space, bright room reflections. If you want some quick improvement and don't want to spend any money, do this:
1. Put two bookcases against the furthest wall from your recording spot or amp(the wall the amp faces). Fill them with different sized books, leave some open spots at intervals, lay some books on their sides. This is a cheap (free if you have the cases and books already) and easy diffuser.
2. Hang thick blankets from ceiling to floor. Hang these about 6"-a foot away from the wall itself (depends on how much room area you want to sacrifice). These will help deaden the room and absorb some sound.
3. Go get some acoustic ceiling tiles at Lowes or Home Depo. These are cheap and come in packs of 8 or so. Get the 4' X 2' size. Take these panels and put 2 back to back so the finished side is face out on both sides. Glue them together and tape the ends up with masking tape. You can cut these panels into "L" shapes for stability and to create backside space to trap soundwaves prior to gluing and place them on shelves around the room or make stands out of wood blocks and set them in the corners or use them as baffles anywhere. These are cheap and easy deflectors/traps and when placed right can create nice sweet spots for playback.
4. Bass traps you are probably better off paying for. I shopped around and got some cheap traps at an online foam wharehoues that sent them pre cut and ready to hang. They were MUCH cheaper than Auralex. Any foam you can scrounge up and put in the corners of your room will help. (start up high and cover the ceiling to wall 'T' area in all four corners then work your way down the corner)
This reply turned out longer than I meant. Let me know if you have specific questions - I've done this and now have a bigger room that I've treated and get great results from. I can help you.
