The wall behind me.


Hi

In my listning room wich is 420 cm * 380 cm.
I have a sofa on/against the wide side where my listning possition is.

On the opposit wide wall my sonus faber cremonas are placed.

Now the wall behind me is not covered by enything yet so its bare.

I have tried to hang a carpet there with audible improvments.

Now my qustina is when I look for acoustic panels for the wall behind me should I look for abersoberation og difussion panels or a mix of both ?

I would think that if your listening chair is really close to the rear wall then you would want to deaden it, absorb as much as possible to help reduce the increased bass response. However, in general, a combination of defraction and absorption is usually the ideal.

Hiya Kal.
The late great John Dunlavy who is widely credited with making some the most accurate loudspeakers, suggested just such an arrangement. Mr. Dunlavy also suggested to me that a 4 foot X 6 foot piece of 4 inch sound absorbing polyester foam covered in thick high quality wool, placed directly behind the listner would be most beneficial.
Thanks for alle the replays.

Evene with a carpet hanging there it get a much more relaxed and dimensonal sound.
Just like if the wall behind me where farther back.

When it get those troldfon panels in place i will let this treat know how it worked out.

thanks

You for sure want an absorbent material, the better the performance the better your sound quality will be.

The one aspect that is not controllable with panels is bass, and the closer your head is to the back wall the deeper the bass will be. It is possible you will find you are too close to the back wall, and by moving away by a few centimeters the bass will tighten and have better definition.

Fine tuning the bass attributes is one of the great aspects of where your listening position is located. I believe you will find with some work this is a terrific spot.

The other issue I believe you will discover is affected (this time by panels behind you) is the spacial clues within the recording will be more evident. You should be able to have some control of the perceived studio space and the sound-stage.
