Time to bring up details of the room I'm working on:
- lenght: max 751cm [24.64'], min 535cm [17.55']
- width: 396cm [12.99'], smaller in the back
- height: 234cm [7.68'], 221cm [7.25'] in the back
- odd shaped in the back
- some extra "chimney wall" on the left side
- all walls, floor, and ceiling 30cm [~1'] solid concrete
- PVC-flooring
- RT60: 250ms
You see it's quite narrow and low-ceilinged nevertheless I went for a mid-field speaker-setting (plus a mono auratone in the nearfield).
For about half a year now I've been examining a lot of variations of speaker position, listening position and wall treatments (reflection, diffusion, absorption). What I show here is my
best guess for now from a listening experience. I'm already working in the room and enjoying solid bass response, strong center image and huge depth of the soundfield. Some listeners asked for wider stereo-image (but I couldn't find it without loosing the tight bass...).
What I'm looking for right now is a more open "feeling" from above (it's quite dead because of the cloud) and maybe a slightly longer RT60.
