Bass problems

Hi
I used the Test tone oscillator and was sweeping the tone in my room I notice that 109hz the bass gets a lot louder. Here is a picture of my studio. I have bass traps in all corners and on the walls etc. Can some one help me get the bass more even. I notice it when I am mixing. the bass is loud in spots and quieter in other spots depending on the frequency.
thanks

Generally in a small room (depending on how bad it was before) to get within a 15 db window is pretty darn good. Rooms that have spent thousands and shaped right are considered outstanding with a 10db window. If you want to really know where you are at I would recommend the following video to test.

I also have problems with that frequency...
I'm close to kicking my speakers out the door....

Can't figure out what causes it and how or why it's happening.
And whats even funniier is your room is more treated then mine .

Put Varitunes V4 and V6 in your room, will fix your bass problems. In my room I have +/- 3dB from 20hz-200Hz without resonances.

To have 15dB span it's not acceptable, if you ask me.

If we can trust this study, varitune Helmholtz resonators don't seem to perform that great.

Reality

It is very difficult to achieve a decent response in a small domestic room.
You need to surrender some of your goals.
e.g. Try to get a decent response in the sweet spot only.
I am finding Dirac Live very useful.
Many LF problems come from the back wall. However to treat it fully would need very deep fibre or Enhanced LF absorber.

Will pulling my desk a little further out from the front wall make a difference in a 109hz. I will probably get a outboard eq and dip it. so it does not drive me crazy

thanks

Maybe, honestly hard to say without testing. It could be also that might need more bass trapping.

How thick are your panels and of what composition?

2" panels hanging directly against the wall do nothing at all at 109hz no matter what they are made of.

Your corner units look too thin. Adding 4" of thickness will help a lot.

Remember, adding a gap behind a absorption panel is critical to getting it down to lower frequencies unless they are very thick.

Even 2" OC703 can do reasonably well with a decent gap behind it.

Hi
the panels are 4" thick and the ones on the back wall are 6 inch. But the ones on the right and left are flush to the wall. everything else has a space behind the bass traps.

The only real way to help here is to know what you have already.

Corner 703 i think ???.... doesnt tell nearly enough. If you truly want help, figure what each and every panel is, its thickness, its gap from wall, its composition, and go to Porous Absorber Calculator and plug everything in.

Knowing where you are is only the beginning. But moving forward is pure guesswork without it.

No offence guys....but he allready has bass trapps. Dispite what they are made of it seems not to be working.

It is time for you to do some proper measurements of your room with real acoustical program like REW, ARTA, to really see how it looks like.

what is the ceiling height? probably should use REW or FuzzMeasure and take a full room measurement and post the file(s).

Integrating a sub is a bit more involved than plug it in and put it "there".
You're going to need to try several spots and find the best one for your particular system/room.

Listening to the pensados place podcast 40 the other day where they had a acoustic expert as a guest . He said that if your room is small , has a low ceiling and square ( every thing that your room is ) it is impossible to fix it . You just try to get the best you can .

Assuming your room height is about 9 feet (from the looks of your picture) this frequency isn't really closely related to any of your room modes at all. Considering your monitors look just about mid height in the room, you might try moving your speakers vertically up and down a bit if possible - it could be as simple as that!

Also, usually the worst possible place you can put a sub is the corner. But, if your response sounds good other than ~110hz I wouldn't move it without testing.

Is that the exact measurement? What's the ceiling height?

I have a room with almost the same measurements and have a problem around 115Hz.
