Audyssey has a lot of capability, but it has its limits; you're asking for things an EQ system can't do. I understand it's a temporary situation and a too-small space, but there are a couple simple things that will ahve a huge effect.
1) move the listening position away from the walls. You want 2-3 feet minimum from your head to any wall.
Your couch is placed so your head is inches away from a concrete wall. Concrete is great for sound isolation, but horrible for listening spaces, because it reflects sound very well. Your ears are receiving a reflected wave that's out of phase at every frequency that's a quarter-wavelength multiple of the distance.
- If you're 6" from the wall, that puts a sharp dip in the frequency response starting at 565Hz, and every integer multiple frequency above, 1130, 1695, etc.).
- If you're 12" from the wall, the dips start at half that, 282.5Hz, and integer multiples higher.
- if you're 24" from the wall, the dips start at half again, 141Hz, upper bass, not low midrange
The real problem is the sharpness of the dip combined with a strong relationship between mic placement and dip frequency. By placing the mic at a bunch of locations with strong dips throughout the midrange frequencies, you're asking Audyssey to solve an intractible problem. With a listening position that's 36", 3 feet, from the rear wall, the dips start at 94 Hz and blend into the room's bass modes.That's something Audyssey can handle, to some extent.
2) Move your surrounds farther from the listening position, and away from the back wall.
The photo shows the surrounds at the end of the couch, against the rear wall. All the issues described above apply, plus a new one - inverse square law.
You may be aware that sound level from small speakers falls with distance by the inverse square of that distance: 1/r^2. By placing the surrounds next to the listening positions, you have a case where the side seats are half as far from the surround speakers as the main seat. The surrounds will be 4x louder at 1.2 the distance.
In addition, the surrounds will have a strong reflection from the back wall, even though they are pointed perpendicular to it. The path length difference will be shorter, so the wavelength affects discussed above occur higher in higher in frequency. The bigger problem is proximity.
- Move the bookcase behind the couch, with enough added space that you can still access lower shelves. If you can arrange things randomly on it, you will get both some absorption and some diffusion. Not a lot, but some, and in the right place.
- Move the surrounds forward, off the back wall, and up the side wall, as far from the couch as you can. Ideal placement is just above hear level, but that assumes you have enough room between them and the listening space to avoid proximity affects. It's the less of two evils, so to speak.
I can't see the couch photo while replying, nor could I attach it, so I'm hoping you get the idea, and can do more adjsutments than I suggest. I would expect a noticable increase in midrange quality and dialog intelligibility in the absence of Audyssey, and some increamental benefit once it's been run with the new positions.
