I’ll take some more pictures and post them. No rush 
You already have some taken 2 years ago (posted above) when I started treating the room.
Here are some others taken when the Magicos arrived (already posted somewhere else on the forum). But you can’t see the back wall nor side wall. I’ll take some more pics.

@frenchrooster I’m constantly amazed by your ability to you keep track of others posts 
It certainly is time consuming!

Looks truly amazing and the attention to detail likewise and the Magicos blend in beautifully - it rings home that some of us ‘could’ be considered a bit ‘challenged’ 
Enjoy Peter
( am replying to Thomas’s post btw sorry )

Thanks Peter! Your system looks great as well 
You’re lucky you could place your electronics away from the speakers.
This is one of many things I would like to change but can’t.
It’s not what I intended 
Trying to correct my room’s acoustic was really fun and quite rewarding. Just wanted to share.
Many things… hardly!? 
Happy New Year to you Peter

I disagree. A bookcase full of assorted books, with differering spine materials, differering heights, and unevenly aligned spines, etc, will diffuse sound - not as effectively as a properly designed diffuser, but far better than a flat wall or glass doors. It will also have some absorption properties, though nothing like as good as a properly designed absorber.
[quote=“Thomas, post:102, topic:5761”]
You can’t absorb low frequencies (under 250 Hz) with foam or furniture.

I think that it is possible for a large soft sofa can absorb into the bass region, though it depends very much on its construction - but nothing like as well as a purpose-designed bass absorber, just better than nothing (although only if the sofa can be positioned in an appropriate place).
But you are entirely right that it is a matter of straightforward science - there is no magic! nor ‘audiophile’ exotic non-scientific treatments to relieve people of excess coin!

I spent 4 hours today in the trains and metro. Big strikes. So yes, I have some time to loose…
I feel however you are a bit sarcastic. However my post was to show others than well done cables dressing is also in the area of acoustic improvements.
One thing that will improve your system, if I may make a suggestion to a great specialist as you, is to put all the ps on a second rack. It really improves the sound.
And we even only have 2 means of achieving our goals, ABSORPTION and DIFFUSION. ATB Peter

Bookshelves full of books do provide some absorption and marginal diffusion, of course, but it’ll be more on the absorption side (around 3kHz). Does it make a difference? Oh yes, it does. Absorbing between 2 kHz and 5 kHz makes an immediate a difference.
Probably, in a certain way. This is something one could easily measure. Considering most sofas are made out of foam I doubt one could expect an effective absorption under 250-300 Hz. If the sofa is covered in leather it’ll have pretty poor absorption capabilities (air doesn’t pass through easily)
I couldn’t agree more. Unfortunately it is quite common 
I was probably a bit « maladroit » to post your pic without clarifying my purpose. So I may understand your « agacement « . Google is not my friend for exact traduction, so I preferred the french terms you understand well.
Just wondering when loudspeakers are designed & tested, are they done in a typical average (whatever that is - see the system pics threads) living room, or a fully sound treated room or maybe a mixture of both?
If the manufacturers could give advice on the ideal shape, size and sound treatments used in testing, wouldn’t that help those who are lucky enough to be able to design a room from scratch to get the best possible sound from them?
As there isn’t such a thing as an average room, a lot of development work by serious manufacturers is in anechoic chambers, as only then do they know what the speakers are doing as opposed to the room. I guess that is complimented with some tailoring in a range of real rooms, though I have no detail.

Here is a promotional video from Magico.
It tells the story of “How to build a Magico speaker”.
Rather interesting.

Hi Rackit.
Regarding room size Dennis Foley@Acousticfields.com recommends no less than 28foot deep and 17 foot wide and 10 foot ceiling height. This will allow a 30Hz sound wave to run freely and disappear on its own accord, at its own length is is a staggering 27 feet 
. Well well that room size takes 99.99% of the population out of the equation. However it should make it a lot easier to treat the room. My room is 20x12 feet and certainly not helped by bifolds behind the speakers, even with baffle fronts of the Facts 1.6 metres in front of the glass. Keeping fingers crossed that 2 QRD diffusers will do ‘ the last trick’. ATB Peter

Well with the light that you have available in that corner, it is a shame, because, IMHO, a beautiful natural plant would perfectly cover that corner, avoiding the high frequencies secondary reflections, and giving you additional life…, .
Thanks for this decorating advice. Whouah! , I am impressed.

Also good for health, humidifying the air and replenishing oxygen levels…
