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.

experiment...

Hi

My sofa is made in souch a way that my head is about 40 cm from the back wall so i ges its just perfect in regards to my room.

The floor is covered with a thick carpet and the big low sofa That pretty much covers the whole lower section of the wall works wonders with the bass.

The bass is not the big problem in my room because i have eq to controlled it (Tact millennium)

Hi don yes i had a tda2200 on with roomperfect and one without so i pretty much know have good my room can sound.

Im looking forvard to getting the panels up .

The panels im getting is also used in professinal studios and big classicmusic recording venues the really dont sell to privat persons but since i work with construction im abel to get them .

I will diffently post pictures off my setup and room on this forum when everything is in place .

It is my understanding that one should have some reflective surface on the back of room and absorbing/non-reflective on sides. Sound needs to reflect off back wall back towards ears. Just experiment with some panels(I like diy because I'm crafty and it saves money)that you can move around to different places/area surfaces.

The sound doesnt need to bounce off back wall if your seat is right there.
