That is a beautiful space germinal. I would bring in a professional room treatment service. You can tell them what you consider important to make you like the sound and they will design the accoustic to suit your taste.

At the bottom 2.5 metres from
The front wall.. top of the speakers around 1 metre.. but can easily put them 1 metre more in the room..

In understand what your are saying.. don’t touch the ceiling.. but absorb low to the floor.. the boxes I inted to make I could easily place em on the floor against the sidewalls.. the lowest point of the windows is 110 cm..

Question is : does this create similar effect ?
Because you are using Dipoles, as a first step I would make the back wall perpendicular with Diffusors.
This is important for the backwave from your Dipoles not to be directed towards the floor but perpendicular back into the room. The space behind the Diffusors, you can use to place quite a lot of Absorption there.

Because of the dipole radiation pattern (cylinder wave) of your speakers, they send very little sound to the floor and ceiling anyways.

I would do that and then listen for some time to re-evaluate the room.
Only one measure after the other with enough time to get acquainted with your sound between the steps.

Or you could use ZR Acoustics panels behind your dipoles in which case you wouldn't have to worry about making the wall perpendicular or need to add any absorptive material.

I have been through room acoustic treatment painfully. I learned some and regretted some. Ideally you can get an expert to come into your house and plan according to your listening position. They do good job I heard from people who used them. But it comes at a cost.
I did myself and am fairly happy with the results.
Best bang for buck will be to start with diffusion panels between dipoles (I have tried different panels, but vicoustics are amazing). You will need bass traps in corners behind speakers. This will take care of most of the needs for room treatment, given the type of walls you have.
With sloping walls like yours, you will have experiment with diffusion/absorption panels in different position and you will find a sweet spot. This will need some effort and time. One thing to avoid is having any diffusion "only" panels close to your listening position. This will create unbearable brightness.
Good luck and let us know how you proceed and with your results. Happy to learn from your experiment.

putting diffusers behind the dipoles.. won't this result in the sound going everywhere ? so mounting diffusers perpendicular or on the sloped wall.... is there actually is a difference ?

Diffusion requires lots of space to work properly. From your photo it looks like your speakers might have to be too close to the wall behind them for diffusers, and it also looks like the sloped side beams/walls might interfere with diffusion. If that is the case then you are better off trying to focus on reducing/eliminating reflections, hence my recommendation of the ZR panels.

Why don’t you reach out to Joël Chevassus who has a listening room very similar to yours and who has achieved some very good acoustic treatment. You are both located in the same country.

Are

are they Magnapan speakers?

no.. Diptyque DP-160

@Addicted to hifi : I have now - like you might know - the Cornwall on test. The thing thatI miss with the Cornwalls is the sheer immediacy/impact of instruments I get with the Diptyques.

In my opinion the imaging is also much better with the Diptyque.

The Cornwalls present a forward soundstage that seems to come to you... whereas with the Diptyques you always want to sit on the edge of your chair/sofa because the music seems to play between the speakers..

Yes two very different sounding loudspeakers.

Different.. but both excellent none the less..

One makes you hear details in good recordings you don’t hear with many other speakers ( Diptyque) there is this intimate connection to the music. In particular with accoustic music.

the other makes even bad recordings sound good ( Cornwall ) with nice palpatable bass and great dynamics. It’s a speaker than can become your friend in a very short time.

Actually I d like to keep em both ‍

isnt there a speaker that combines these qualities ??

Excellent idea to keep Both.i use klipsch and Magnapan speakers and swap them over for a change in sound.

Not one speaker that I have heard can do everything,that’s why i have 2 different speaker systems.

What do you use most ? Do you use different amps ? And what music do you prefer on the maggies ?
I use a mcintosh mc152 150 watt amplifier on the la Scalas and a mcintosh mc462 450 watt on the magnapan 30.7s. i like the klipsch for pop and rock music and the Maggie’s for classical,jazz and acoustic and vocal music.i use the klipsch more than the Maggie’s but I love both of them.
