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 ?

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 .

regards
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.
Hi

I have posted the same qustian on a danish hifi forum and the advices i get are so contradictiv.

Actually there are so many different oppinions on the subject that its useless asking.

What i do know is that when i have that carpet behind me hanging 1 cm from the wall(around 35 cm from my head) i get a more relaxed and more open sound emerging around me

Maybe the carpet is all i need?
The sound should not be bouncing off the back wall if your seat is there as the interference between the direct sound and the reflected sound will be severe in the midrange, depending on how close you are to the wall. While I do not recommend completely dead rear walls in general, in the specific case where you are within 2 feet of that wall, I do.
