If you want really cheap or free sound treatment fill the room with all your useless junk and soft things like teddybears extra pillows etc. Cluttered rooms sound better than empty rooms. These work as both diffuser like and absorption. And a rug on the floor.

What is "low cost" and what is "effective" to you? I spent about $1500 in treatments on a 10'x10' room on a blend of 4" and 6" GIK Alpha panels, 4" ATS bass traps, and very heavy acoustic curtains on a large window. I feel the investment was a great deal for the impact on sound quality. I'm guessing you are looking for much cheaper though. If you have the means, DIY materials are available from ATS, Acoustimac, and others. Having done it, DIY can save a bunch of money, but it's a lot of work that's messy and requires space, and handling and cutting all the FR701 sucsk (or whatever fiberglass panels you choose).

Sometimes I think questions like this are "secret shopper" stings set up by @amirm to gauge members' thinking. The sad truth is that a 6'6" x 6'6" room will never be a satisfactory room for speakers. Just can't be done, at any price. Buy a comfy chair, decent headphones, bolt on a buttkicker, and spend the rest of your budget on music, weed and beer.

It depends on your objective(s) Do you want to keep sound out? Do you want to keep sound in? What frequencies are you trying to keep in / out? Do you want to control echoes? What frequency echos? Are you designing for live-end / dead-end? Do you own the building? What is the current situation of floor, ceiling, walls, and doors. What is the floor loading capability. How is the room ventilated and climate conditioned?

An all-in-one solution is a modular audiology booth, sometimes you can find them second hand.

I have a room 2x 2metres can I treat it myself. How?
The lowest standing wave you will have in your room is 85Hz, hence most acoustic absorbers will do a god job. However, I expect most problems will be caused by reflections doing ping pong between opposing walls and between ceiling and floor.

If you have bookshelves on opposing walls you may not need much absorption on the opposite wall. If you have large furniture like a bed of sofa then you may not need anything to be done to the ceiling.

If you explain further or post pictures of the finished room we can advise further.

Why? What will be the insurmountable problem?

The size. You say:
If you have bookshelves on facing walls you don’t need much absorption on opposite wall. If you have large furniture like a bed ...
A wall of books would reduce the width to 5'9" ... smallest bed is 30" x 78" ... so free floor space is now 39" x 78" ... a 30" door needs to swing open somewhere, so now you have 39" x 48" for a chair and two speakers. Minus more for even the thinnest absorbers ... good luck with that!

Why do you need absorber for such a small place? The furniture in the room acts like diffuser and absorber.

It will be difficult to keep early reflections and direct sound seperate. We need at least 6 milliseconds between the two, and that’s roughly 1 meter.

So basically you have to turn the space to an anechoic chamber.

The Facebook Room Acoustics: Absorption, Diffusion, and Soundproofing group is a pretty active.

Why do you want them as separate?

But now, 15 minutes later, you're saying no absorbers are needed at all ... make your mind up! And tell us how you would set up a music system in a space 3'3" x 4"0"?
