Ok guys...
That is simple...
I want to treat my home studio, but i dont now what to buy.... is so much offer....
i want to now the material you have bought and if have made a good result....
Is a little studio 3x4,30 m so i have very problems in the lower frequency range.....
Any advice will be aprecieted.
I have 4 basstraps and 4 (to put in the wall), but i dont like the result.....the material is bad our is not enouf....
That is why i need your "inputs", im really lost in here...
Thanks |

Well i made my own bass traps, bought some rockwool panels they were 4 inch thick & had a density of 100kg/m3.
I have 16 panels in my room right now & probably going to put another 12 in the future.
4 bass traps really aren't enough to see much of an improvement, but they're better than nothing.
You can also go for something like Owens Corning 703/705 instead of rockwool.
To address low frequency problems treat all the corners of the rooms, remember it's not just the wall corners it's also the ceiling wall & floor wall. So every room has 12 corners.
Ideally you should go at least 4 inch thick & if possible you can even do superchunks in the wall corners (slabs cut in triangles all the way up to the ceiling). 4-6 inches placed across the corners is good as well if you can't afford to do superchunks.

ok...but you can tell me the especific name of the material, or some links to buy it...
About fiber and rockwool, in dont want to used because the possibility of cancer(i dont now if is true or note but very people talk about it so....i dont want to try in my self).
My 4 basstraps are made by basotect, but in the last things i have read, they dont work well in the low areas.....??????
Like i say before, im lost in this subject =( |

I'm sure you already know, but for the benefit of other people reading this thread it needs to be said -
Foam is useless! It stops flutter echo from high frequencies, but anything else will pass right through it and reflect back.
I am currently building 9 traps (midrange) using RWA45 Rockwool (45kg/m3).
There is some debate over whether higher density rockwool is actually less absorbent - the theory is there needs to be at least a certain amount of air between the fibres before it starts becoming either reflective - or acting like a solid that transmits sound through it. I couldn't find any higher density, but 45kg/m3 seems to be a good starting point.
There is no chance of cancer, the more dangerous fibreglass has been phased out, and the only problem you will get from rockwool is f*kin' itchy skin. I handled it directly and had red blotchy arms for about 5 hours. It's unpleasant, but it won't kill you.
Use a cheap paper disposable mask, seal it into your boxes/frames with fabric and vacuum after. |

and if i put in all my walls, rockwool and then put the fabric (can i make that???), that will work for example to reduce de reverberation????
problebly it will work well to reduce the reflex from walls???
and another thing...
anybody have use rigid rockwooll???
Really thanks for help |

i have looking for a good rockwool and i find this very interesting one, because about is capacity of absortion....is very constant (the most that i have see in my research) in the all frequency range....
I dont now if it is good, but i thing is good because is absorv more a less the same in the all freq range, and i thin is a good star.....
I thing i go glue it in all my walls, and made basstraps with that too.....
what did you thing about....please someone...
that is the link

thanks guys....really thanks for all the help  |

do you used???.....its work fine in the low area????
is very cheap....
how many do you use.....
do you put it in all your walls????
i have 4 made it for basotect to 2 of them in the 1º reflexions points and the other 2 in the back of my monitors....
for a have read, the wall behind the monitors have to be absorved at 80% to 100 % with absorved panels....
its true????
and if i put all my walls with that??? the reverberation time will go down????
Because that is my first fuc..... problem in my little studio....
and the low area too |

thats just about the wide absorbers not about the actual basstraps..but anyway..the 100mm ones are really great..

Has anyone heard of making resonance tubes.
I talked to an audio engineer one day who took two large tubes from ceiling to floor and put two subwoofers on each end. He then took a microphone and phase inverted the input. The audio that the microphone detects is inverted and drives the subwoofers on the top and bottom of the tubes. In theory this phase cancel's the frequencies that are detected at the microphone. Creates a dead zone on your corners which absorb (cancel) the frequencies detected at the microphone. Effectivly eliminating those frequencies and not having them bounce around.
I have schematics for building these things if anyone is interested. I think that you would need to put some kind of filter to the mic input so you select only the bass frequencies you wish to cancel.
Sono-Tubes...The guy I was talking to was raving about these things.
What do you all think. BS or good idea?
