One thing some may find wort to know.
A professional studio does NOT want 000 Refelections!!!
A pro studio wants EQUAL and mediocre reflection of soundwaves of all frequencies (whereas a little more in bass is tolerated).
Actually the prototype is a NORMAL LIVINGROOM, where the music will be played in.
The funny thing is, that a normal living room, with carpet, couch, table, curtains, furniture and all other kinds of funny obstacles results (due to its chaotic nature) in a very desired reflections behaviour. A living rooms diversity is optimal to "eat" all kinds of frequencies in an equal way, but still will not absorb them all, which would result in a "dead" sounding room.
The thing with accoustic treatment only comes into play when a room is very small or only dedicated to music, which obviously misses all the chaotic obstacles. only in that case (or when a also otherwise used room has hardfloor and few obstacles) we need to start optimising..
So before you jump on the absorbers train check if your room might not be quite optimal by its nature, cause also being your bedroom etc. etc.
Note, that small rooms are always a problem.
Totally ! Maybe it's smart to start out by placing absorber-panels to the left, the right and the top of the listener's position to attenuate the first reflections and go from there ?

definitly!
Maybe you know the mirror trick?
You sit in your listening position
a friend takes a portable mirror and moves it a long the wall to your right.
you keep your head in your listening position but look into the mirror.
As soon as you can see a speaker in the mirror you know that the position where the mirror now is, is the position to put your first absorber.
its a company which sells a room meassurement program plus calibrated mic+preamp.
Its not easy to use at first, but once you know it, its easy. you can even do some meassurements with the demo version and any mic, its not accurate but still you can make "before - after" comparisons.
all over hard+soft its about 500bugs, but if you are a couple of guys together and at least one is a bit of a geek in that area you can buy it and then meassure the frequency response of your speakers in your room as well as the reflections and more quite accurate... if you hire a guy to do it he will charge the same..

But I'm writing music to be played outdoors, not 'NORMAL LIVINGROOMs'!

This is the question!!
How this work on outdoors systems...and in a Club place...How I can optmize my system to listen like that places?
I can get a flat sound and without distortions (when I talk distortion i talk about reflections, delays, etc) on these systems (outdoor and general club place)...?
I don´t need a perfect mix room, it´s impossible by my room size..but I need a good place to produce my tracks..when I will listen like the listeners on partys or clubs...
I produce my tracks on this room and when I play on last week in a party with a good sound system (10x SB1000 Sub and 8x KF850 in each side) many friends (producers with more time in road)comes talk to me good thinks about my mix and mastering...that takes to me believe it my room is not sooo bad...and I can produce in that conditions and get a really good sound, not perfectly, but good..and better then many artists (here in brazil)...untill get a best place to make my studio...
And! let´s help me to get a good sound on my little home-studio...
Regards, thanks, and a pot of snacks!

Just buy some rockwool & stuff it in these ready made bags:
Be aware the so called "super sub bass bags" are only 15cm thick, so not really going far down. If you want to absorb bellow 150Hz you really got to have thicker material, or two of those as a sandwich
Actually, the SuperSub Bass Traps (when used with OC703 or 6lb RockWool) will yield a great absorption result well below 100hz.
Here is a graph showing the various absorption curves as measured at RiverBank Acoustical Labs:

There are a series of tabs on that page that walk you through the entire testing process including final data, placement, etc. I hope that is useful to folks here.
Each Ready Bag comes with an integral hanging system, (via a series of 4 surgically sewn in straps on the Ready Bag) hanging hook, drywall anchor, 4 polycarbonate peel and stick plastic corners, our proprietary micro-suede fabric and an invisible zipper.
If you truly want to do DIY, you might have a look at this free tutorial I created and offer at no charge:
I hope some of this information may help answer questions. Please let me know how I can help anyone here improve their room acoustics as I am happy to assist.

Wow, I'm impressed!
So practice beats theorie! I'm always happy with that!
are there also results for the high freq absorbers?

Also,
In addition to the free tutorial I posted above, you can find out more about DIY acoustic treatments at http://www.basstraps.net. This is a user sponsored forum that is just getting started, but where the goal of the site is to inform and help folks build acoustic treatments from scratch and without using pre-made acoustic materials from us or other manufacturers.

@ Fuzzikitten
Jokes aside, no one is forcing you to buy their product. You've gotta admit its convenient for people who don't have a lot of time to invest in choosing fabrics & covering the panels up.
Besides, most studios won't consider it a large amount. Not everyone is broke like the majority of us amateur producers.

Ready acoustics also have great customer service so i always recommend them!
Well, thanks very much!
But I'm not here to sell anything. I only came to clarify some information posted above and to link you to a totally DIY approach to acoustic treatment. That's all.
Thanks for the vote though mate.

Ok..might get on here as to not become too offtopic in other threads..
@ d2 , i know foam is not the best, but this one is pretty good actualy..its designed by BASF..here you can see an absorbation scale..
i was going to make some DIY ones, but here in germany it is not possible to get rockwool with the necessary density to absorb low frequencies..therefore i decided to go with these ones..

Its not so much about density. It is about gas flow resistance. 45 kg/m2 will suffice. Its about how thick and also leaving an airgap behind.
