I am moving to a newly bought house very soon.

Have reserve a small room for Listening Room for my Stereo System consist of Marantz CDP + Primare I20 + ProAc Studio 125.

My room :
:wink: - L/W/H -- 11 x 9 x 9
- Heavy curtain at the back wall of the Hi-Fi.
- Book shelves at the back of the listening position.

Question: :roll:

1. Should I use Wallpaper for the room ? OR

2. No Wallpaper but hanging rug on both left & right side wall?

3. Dealer suggested Wallpaper due to even absorbing / difussing capability.

Need advice asap.

thanks.
