Hi Ethan, thanks for inviting me here. Basically, I have $1000 to spend on treating a 15x12 room. I plan to invest more later, but for now I have to stay in budget. I've got a ton of foam that I've randomly put up because I don't really know what I'm doing, but I've heard that a square room is not the greatest idea, so I opened up the closet doors to "break the room up" a bit. I've read your posts about treating the ceiling and right now, I have nothing up there. I don't even have bass traps in the corners because every time I try to buy something, someone tells me there's a better way, but the don't tell me what the better way is. It's a rented house, so the carpet stays, but I've read your posts about laying down sheets of wood? I was thinking about buying this Primacoustic kit here, but the pictures show it being used for a control room and I'm trying to treat a LIVE room for vocals, drums and instruments. I was also going to buy 4 of these and put them in the corners about 5 feet off the ground and add more above and below when I get more money. Here is a panorama of the room.

Hey Monaco. If I may say: welcome to the forum. With $1000 you can do a lot of good. Many people prefer commercial panels such as Ethan's Real Traps but you can build some with Owens Corning 705 FRK or 8lb Mineral or Rock wool and get good results. I have about 30 panels of varying thicknesses and spent only around $300. That was about 7 years ago and in El Paso, TX and I got a good deal but still... If you use either of those materials I mentioned, treat your early reflection points and cover your front and back corners with emphasis on your 3-point corners you can't go too far wrong. Try to avoid shipping and buy locally if possible - that will save you a lot.

Thanks to hexspa who has been contributing a lot of good advice all over this forum. I'll just add that if you have "a ton of foam" you can make it work better two ways:
* Double up the panels (face to face) to make them twice as thick which absorbs to one octave lower.
* Panels that are already 2 inches thick or more can be improved by mounting them backwards. That is, you put the sculpted side against the wall with the flat side toward the room. That puts more of the absorbing "mass" away from the wall where it absorbs better.

Sure, though it's more difficult to attach foam with an air gap.
