The space behind Dipoles should be uniform and symmetric.
Ideally the whole front wall should be one big (itself repeating) diffusor.

We need more bees. It’s a small sacrifice Ron but insect hotels are big business going forwards. Think of all the honey!!A

That should only be an example.
I'm very confident that this can be done aesthetically pleasing, maybe even with the already existing wood panels
Something like Sound of Tao already suggested here:

By the way, iIrc I recommended this to you already before, VERY early in this thread...
Thank you for the suggestion, Christoph.
But why do you believe ex ante that diffusion at the front wall is ideal for all dipole planar loudspeakers?
What sonic problem do you think I need to solve with diffusion?
How can you know in advance of me setting up the stereo and hearing it for the first time that diffusion of the rear wave will sound better than an unadulterated rear wave?

The BOLD is what I suspected but did not really know for lack of exposure. I did not know about the diffusion on the front wall. Symmetry would seem to make sense.
This is my experience.
With diffusion (behind dipoles), the sound(stage) gets bigger and the sound itself gets more natural, more refined.
When you were at Henks place, did he already have the full wall diffusor?
I have been at Henk's place several times and I have heard his system also several times in different configurations.
The single biggest improvement (I experienced at his place) was when he installed the whole wall diffusor behind his Grands.
I am very well aware that not everyone can implement the front wall as one big diffusor but it would be optimal.
I can't do that either because of my panoramic windows but with your orientation away from the windows towards the wall, I would not hesitate one second to implement that diffusion behind your dipoles
A flat/even surface behind the dipoles (in combination with the uniform and symmetric setting) is already very, very, very good, but (controlled) diffusion is even a little bit better.
That is the icing on the cake with a cherry on top

Why do you believe that diffusing the rear wave sounds better in every case?
I’m not saying it’s the case with this, but that is a wise thing to ask. A lot of the time the answer is to solving the problem of how to change the sound, not an actual problem for representing the music.
In your room, with your dipole planar speakers, I would diffuse the back wall (behind the speakers) with vertical RPG diffusors to keep the energy on the same hight it was radiated from the speakers.
I would NOT use horizontal RPG diffusors or skyline diffusors because they also diffuse the energy up and down (i.e. in all directions)
I don't want to "sell" you something, I just say what I would do in your situation

Excellent post - the critical and hard part to achieve is the spectrally-correct backwave energy. This aspect is also carefully exposed in the F. Toole book, that warns us that most acoustic materials sold in the market are NOT spectrally correct, particularly when used in small rooms. Acoustic treatment (or not) of typical listening rooms is mostly an individual case, the nice rules only partially apply in a rather large room. Remember that most acoustic materials sold as diffusors absorb more than some foam absorbers and that efective diffusion needs a large minimum space. Full range diffusors applied two feet behind our speakers are not diffusing at all ...
IMHO many people, including some known speaker manufacturers, generically advise against the use of diffusion spaces behind their speakers because they know that most of the time it will be incorrectly done, making more warm than good.
Again IMHO, the only place place for real and complete acoustic data on acoustic products is the RPG page https://www.rpgacoustic.com/ . All else needs a lot of imagination or plenty of previous experience with products.
Good information.
May I add that a lot depends on the speaker and the room.
Just check my Martin Logan "Aerius" speaker location because I pull it out from the wall a few days ago, measures at 35" out from front wall. Owner's manual says 2-3 feet is recommended.
With a small room like I have and record rack behind the listening position, I cannot get my head further back than about 12 feet, so speakers 9 feet into the room isn't going to happen.
Until I take a small wall out to get my speakers at least 6 feet apart, they will remain at only about 4 feet apart.
It's kind of crazy how good they sound despite these current restrictions. Heck, some speakers are 4 feet wide.
Agreed - imo the best approach is to engage the services of an acoustician, who can can take detailed measurements and then tailor room acoustic treatment recommendations to your specific situation (room, speakers, listening position, decor, budget, whatever).
I used to be an enthusiastic armchair-quarterback amateur acoustician, but since having been in several rooms treated by a professional (Jeff Hedback), I try to refrain from anything other than vague generalities. What a real pro can do, even from a distance using remotely-made recordings, leaves me in the dust.
By way of crude analogy and at the risk of over-simplifying, reflection and absorption and diffusion are sort of like inductance and capacitance and resistance in a crossover. With a crossover, the best results arise from having the right values of inductance, capacitance, and resistance in the right places. Likewise, with room treatment, the best results arise from having the right amounts of reflection, absorption, and diffusion in the right places. In both cases, the services of someone skilled in the art can make a very significant difference.

Unfortunately, with the Wuhan virus keeping Southern California in stay-at-home mode, the work on the house stopped dead in the water in late March.
All we can be reasonably confident about is that the house, and the listening space, will be finished sometime this decade.

I think that place is cursed. Are you sure an audiophile didn't die there buried in an avalanche of his component clutterphilia?
