gg yeah, really snowy feeling when i enter the room!
i feel like i can grap the instruments from the songs,
and i feel everything more directly into my face... without roomreverb.
find no other words for it...
i did some meassurements with the hs50...
the 50hz peak is really big >.<
what you think about it?
this signal is reproduceable...

bass range is always the biggest problem in small rooms..people spend thousands of euros just to fix certain frequencys. One of the most problematic frequencys is 120HZ wich looks quite good in your room..
you can easily get used to that 50hz boost i think since usually you cut your sounds higher and bass well, try & error i would say..do a few mixes and see how they translate on other systems. maybe you can even lower that area on the focals as well to balance it..
it even could be just your speakers that cause this unbalance..try it again with the focals 
what mic did you use for the measurment and wich interface?
cheers

yes move the speakers and/or listening position.try to set them so you don
t have the same distance from side walls to the walls in the back and distance to ceiling to floor too (try to have different distrance from the monitors to every wall around ) . maybe put them very close to the back wall or oposite dunno..
dunno if your measurment are correct it s far to be flat , 15 db peaks is a lot, tracks sound good? pitch bend a sine wave maybe from 30 hz to 500 hz or more to check if the low is flat . moving your speaker just by 10 cm you can have very big change in the low end

new meassurements:
(i setted the target line by myself)
what you think about this horizontal/vertical comparison...
here are some datas about the mic http://aa.peavey.com/mics/pvm480.cfm
the 50Hz peak is about 20db lol
and the 90Hz valley nearly the same^^
my speakers distances are 67cm from the side and 60cm from the front wall and i sit at 38% of the room...
thx zork, maybe ill borrow one, if i got my focals...
i did much meassuretesting and the 50/90HZ peak/valley are the same most of the time... www.soundcloud.com/orgytime |

Your absorbers in the corners are 4,7 inch thick?
The main problem with broadband absorbers in the thickness range you have is that they don't work with very low frequencies.
As far as I know real basstraps for corners are usually thicker, something like 10 inch and usually of material with low density as the heavy wool starts reflecting when the absorbers are too thick.
I'm with the others. You should move the speakers and try to find the best position.

horizontally is the worst you can do since the super cardioit pattern has its Muffled area right in direction of the backwall reflections..vertical is the way to go but with super cadioit you even got a problem with important frequencies from the ground..i attached a very proffesional picture to make this clear. This problem even has a certain name..but i don`t remember right now sadly..
a thicker carpet on the floor in your working area might help for those reflections..

I think higher density would be good since it would reflect just the high frequencies ,wich got less power but absorb the low frequencies with more energy..its basically the same with those egg cartons for example..they might do something(just a littl) on the high frequencies but do nothing on the low end..

Yes you're right. With lower density I meant 703 or equivalent instead of 705.

loool ok... i read tonns of basstrap stuff.
they said at least 4inch rockwool thickness.
i took 4,7 and you tell me the rockwool is to dense for bass absorbtion^^
i spended 170€ for a mic and its useless...
just mentioned that the yamaha hs50m only can go down to 55Hz lol, where does this peak come from?
hey zork, just wanted to order this mic, what else can i do with this mic? just room meassuring?
i also need 2x [2,5m XLR-female/Klinke Cable] but it seems im unable to find it, maybe you could send me a link from this cable?
cheers

I didn't say that it's too dense for broadband absorbers with 4,7". I was referring to superchunks/bass traps for corners with a thickness of 10" or more.
4,7" and a density of ~50kg is perfect for broadband absorbers. However it's not only about the density but the gas flowing resistance. And this resistance is not always the same.
Anyway what i wanted to tell is that broadband absorbers are limited in the frequencies and that they don't perfectly work with very low frequencies.

actually its just good for measurments , but sure you can record other stuff as well.
http://digitalaudioservice.av-cablesystems.de/index.php?cat=c7_Instrumentenkabel.html
but just write them a mail with your order and they will place it for you and even confect your cables..
its not that the speaker doesn`t go below 55Hz but there is the point where the -12db pro octave starts..
and if they then produce standing waves in your room it looks like this 50hz boost..
Ah now i know what the effect is called...its the audible comb filter effect :german"Kammfiltereffekt"
its like the wave go on the ground and arrive at the listeners point later than the direct waves..that causes phasecancellation ..so its the same point why absorbers are used anyway..but i forgot the name, a thick carpet helps..

thanks!
the vertical meassurement dont looks that bad, right? (except the bassarea^^)
i have to sort my brain now^^
ill inform you if i got now infos
