Acoustics Wall - The project.

[haraldo]

I spent years upon years, getting where I am with the music rig, but I did not do the things with acoustics, so in 2022, I decided to make a change.

Build an acoustics front wall, that does this:
- Surrounds the TV to make the TV flush mounted in the wall
- Maximize acoustics benefits, iainly absorption
- Make it a stunning statement of modern visual design.

I contacted Art Novion to get some ideas and inspiration and they sent me this:

In this thread I will document, step by step the process of my acoustics wall, from concept to completion

Acoustics wall - Art Novion

After spenind more than half a year researching all kinds of panels on the market I enden up with these panels from Art Novion, Portugal. This is not cheap at around $1700 for a package of 10 panels, but they look stunning, and perform really well, I think. Quietly Siena K, NaruraL OAK

The panels arrived on a large pallet

Unpacked, wow

Acoustics wall - toolset

Some of these panews had to be cut and extremely precisely, so I needed to get some precision tools for this cutting, I don´t have but I was able to rent a professional De Walt battry driven track saw, making it possible to do precise cuts with millimeter precision.

I also used a simple miter saw that I have in order to cut the 2" x 2" studs for the framework.

Acoustics wall - Building the framework, part 1

Here is the starting point, room for improvement

Building a skeleton to support the acoustic panel, leaving room for Rockfon Industrial 2" absorbers, depth exactly matching so that the front of the acoustic panels will be flush with TV.

Everything is painted and all parts of the framework that could be visible is painted matt black so that it will match the absorber part of the panels.

Acoustics wall - Building the framework, part 2

Framework done, time to cut and fit Rockfoon Industrial absorbers, the absorbers are very easy to cut with a special knife dedicated for this use.

I you look at tha last photos there are free room at the bottom for dedicated cable trunks, so that all cables will be hidden, behind the acoustics wall. The power cables, speaker cables and signal cables are also split to spaced dedicated channels.

Acoustics wall - Fitting the panels

Fitting the panels to the framework, this is simple by just fastening with small screws that go into the 2x2 studs.

Almost done

Also at the side, to be hidden behind the bass traps I added some extra power connectors with filters, to connect the subwoofers, the idea also being that any noice from the subwoofer power supplies should not be going back to other equipment, if it has an effect, I don´t know
But it makes for a very clean, good looking, setup

Acoustics wall - Finished ... (almost)

The finalized wall, butg now I realize the white DIY bass traops stand out too much, so I had to do something here too.

Painting them black
Maybe not?

Acoustics wall - Finished ... (take 2)

I added a real oak panel bedind the AV rack to make it look cleaner and hide the cable mess

I had more acoustic panels so I fit them to the front of the bass traps, I think better

Getting there ........

Studio Mode

I also made a "studio mode" where I add much more absorbers to kill the first reflections on side walls and reflections from the back of the speaker.... probably also adding panels in the ceiling as per Art Novion recommendation in the first post.

The result ...... The Art Novion products are simply stunningly amazing
I think mission accomplished, it looks good ...... and music to die for

Bravo , nicely done !

Thanks a lot

Just hope it could be some inspiration to others

Well, it certainly is front of the pack for acoustic treatments, as it looks like a panelled front wall. In general the best rooms look as if they have not been treated when in a myriad of subtle ways they have.

One big misconception is the first reflection issue. With good speakers you absolutely do NOT want to kill it. If the speakers off axis response mirrors the axis response, then those first reflections are in general highly beneficial and really open up the sound stage. The design of the cabinetry on my mains, really scatters the off axis response which is highly beneficial. This is another design tip I adopted from John Wright in his last design right before his untimely and early death.
