Dirac ART is now running on beta FW for Denon Xx800H AVRs!

What you describe is using WRONG absorption, means not broadband absorption. This leaves you with a mushy room (still resonances and decay in the 100-250Hz area) with no HF energy. With proper full range absorption your room stays balanced and just get's more controlled.
Professional rooms have/need a lot of absorption area - but you don't hang a few panels, you do a proper concept.
It's always easy to recover HF energy - it's very hard to modify a boomy room.


Japanese walls are traditionally made with paper. Studio and good home cinema rooms have acoustic fabric walls so you hide and are flexible with the treatment behind it. You also hide speakers behind it.
Like these examples:

Exactly

Not at all trying to tell you what to do. Seams like you have your own way and so your should peruse it by all means. My own experiences are entirely different than yours.

nice place , it’s off topic but you could treat the back wall and if you want add some cloud

Since the release is practically confirmed at this point, where do we stand on release date rumors ?

 

[dlaloum]

Humm, OK, I envision "fabric walls" as those in a Japanese home. totally inappropriate for a home theater room.

I Imagine it as acoustically transparent fabric "fake walls" - behind which speakers of choice can be positioned (invisible due to the fabric) and then appropriate wall treatments applied to the real walls, also invisibly....

But yeah - would be nice to know what is meant by "fabric" walls...

Clearly you are one of those people hogging the Gallo speakers I have been trying to find!!

I don't know that I would do that in the bedroom - but nice gear...

I believe the rumour says "september"...

The speaker exists and the chosen 12" is more punchy as the really good ScanSpeak 8" drivers I used before. There are not a lot of 12" which are good to use up to higher frequencies (ScanSpeak, SB NRXL or Purify 10") but it's no problem at all with the right drivers. Dividing that area to 3 drivers brings additional problems.

I hope I can realise such a setup this year.



For the cinema of the first picture I built 8 pieces of 15" subwoofers, 4 at the front and 4 at the rear. They use a Trinnov system with a dedicated channel for each sub - way more expensive as ART but of course works well.
When ART works without a subwoofer system and redirects the LFE channel properly you could save a lot of money which could be invested towards the main speakers - the over all price would be realistic and results should be outstanding.

Anyone needs a crazy good home cinema to proof a concept?

p.s.: Maybe we should go back to topic? I would rather choose a Marantz preamp for such a project - still way cheaper as a Trinnov or Storm Audio.
But using 7 big floor standing speakers with the Denon and ditching the subwoofers would make an interesting price/performance cinema.

Very very nice speakers and indeed very capable for ART!

I already have 6x PHL 6201MNd for my new LCR speakers but I'm thinking of using 6x SBAcoustics SB34NRXL75-8 instead or even 12x of the smaller WO24P-4. The smaller woofers would allow more space for a bigger TV later on.

Very nice speakers and components! I'm quite sure ART will be very useful in this room.

Both are great and the "diamonds" in the SB Lineup. You have seen my measurements of SB34NRXL at diyaudio?
2 woofers positioned like I did have benefits with room reflections - so I would go for that. I use SB34NRXL up to 450Hz and it plays really well and integrates with the 3" dome. Not many drivers of that size are able to do so.

So I would suggest ... use 12x SB34NRXL and get an acoustic transparent screen

p.s.: send me a dm when you want to discuss to more detail, don't want to crash the topic here.

Of course I meant the optical "walls", not the real structural walls ...

When you are serious about audio you need to address room acoustics. When you are serious about room acoustics you need to treat surfaces, not hang panels. An acoustic transparent screen and fabric wall covering is the way to go when you have a dedicated room for cinema.

a friend of mine that back in the day designed studios and helped me treating my room told me that this kind of houses had a big advantage for the bass frequencies because the walls were thin and the room has less problems in the low frequencies

Yes, but then you have to make up for the "leakiness" with substantial power/spl's

 

[Oddball]

It's actually living room. An Oddball concept.

 

[Oddball]

I certainly hope so.

But then once you get at this level it is already 3/4 of the way. I only have issues with below 30hz bass, which could also be addressed by DBA if positioned differently, but not really practical in my setup. So my real expectation from ART is to clear the below 30hz bass and tighten up (a bit) the 100-150hz range that is outside of my sub/DBA coverage.

Like American vs European houses - I often see room decays from american houses which would be way harder to achieve with massive walls.

Paper walls ... your neighbour would have fun with your home cinema . But it's WAY easier to drive 6dB more SPL as treating room resonances.

 

[Ciobi69]

The last of the problem imo

If you are already invested in the concept of Dirac over, say, Auddysey then you'll already have the Dirac Live and DLBC modules by default. And have willingly shelled out for these.

So the cost of DART is a small increment given the promise of what it can achieve if the result works.

I plugged in my X4800h into the 'available' models for DART the other day on the Dirac beta site and it still comes up with model unsupported for DART. I guess that will change as and when D&M adopt it.

Phil Jones shared a screen with Frederic Filleul in a Masimo YT Live stream showing the A1H in Dirac with the ART tab under DLBC. The video gets interesting from 32:20

I registered here just to say this - because I've been lurking here for months, like some sort of sick person, awaiting the release of ART for my X4800 - I noticed that I received some new firmware component at some point in the last week.

On Aug 4 the firmware string (via web UI) reported 5700-9011-E071-8880, and today it reports E091. My best effort to decode this non-public version string based on other reports tell me that this is a non-major platform update, possibly a sub-component update, like Dirac. (5700 is probably the hardware platform, 9011 is the major software/OS, and 8880 I think might be a series or era marker)
