But were you ever able to fix this? Or you were forced to go back to 3 subwoofers?

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

I was forced to go back to 3 subwoofers.
Wow... so sad to hear this. For you and for me (although I use a X3800H), as I'll receive my fourth sub next week and now I'm scared.
That's strange.. maybe Dirac has some issues with your specific room and/or sub locations... Or it was a bug and it is now fixed? When was that?
Well at least in my setup, I saw no such problems with four subs and a 4800 with DLBC...
Ok, considering 3800 and 4800 should be identical on the software side, this sounds reassuring. Thanks for sharing.
I did not fight hard for this, I did not even try to contact Marantz or Dirac support, because it should be matter of a couple of months before ART comes, and things will hopefully change.
No worries
I only have a very suboptimal living room setup though, my speakers and the MLP don't sit symmetrical in the room and along the smaller axis rather than the more optimal longitudinal axis and I sit very close to the back wall. However, still get a very smooth response in the deep bass and du to the very "leaky" soft walls of my very old wooden house, which absorb a lot of bass instead of reinforcing it, I actually get pretty good decay times in the deep bass as well.I feel like every subwoofer I added, did improve the sound with going from one to two representing the most noticeable change. Getting a third and a fourth also contributed more than I thought though, mostly in terms of offering an even more enveloping sound, coming even more "from all around" and offering more sense of pressure at lower volumes. I only recently upgraded to more than two subs though (I had two Arendal 1723 1S and bought two additional used SVS SB13U, and in between I had 3 subs running for a few weeks). So maybe replacing the Arendals with two bigger ones (more driver surface area) would have had a similar effect, no idea...
If I had to guess though, I'd suspect more subs is better but they have to be the same subs or at least similar in performance. I had an old SVS SB 2000 running as a third sub in tandem with the two Arendals for a while but it didn't sound that good, the SVS just couldn't quite keep up with the Arendals. So they didn't gel that well. When I got the two SVS SB13, I at first only switched out the SB 2000 with an SB13 to see if it worked better (in the exact same spot) and oh yes, it did. Immediately, I thought: "Finally I got my punch back". The bigger SB13 matched the Arendals way better - which makes sense since they are similar in size and performance.
I kept this 3-sub-setup for a few weeks and I quite enjoyed it, it had more punch and deep bass power, I felt "more pressure" than with only two but I had a similar feeling than
I found a third sub to be better than just two (although I only tried one position) but the fourth sub balanced it out even more, now I have two in the front and two in the back on either side of the couch (but I have a very suboptimal setup since it's a living room so it's not symmetrical).
I'm currently very happy with the four subs and I think Dirac did a pretty good job integrating them. Still, I'm constantly wondering, if four identical subs would sound better Sometimes I think the bass could be a touch more dry but overall I'm pretty happy and the four 13" give me a ton of punch in my 19m2 room!
Here are some measurements (all L+R+Subs, XO 80Hz, with Dirac BC on my Denon 4800):
Two subs (one in the front middle one in the back left):
Three subs (one in the front middle one in the back left, one in the back right):
With the SB 2000 in the system, it measured good as well but it didn't sound very good.
This is how it looks now with four subs:
As you can see, Dirac didn't make anything worse FR-wise like in @slaweks case. However, in my case, it also didn't have to do much since the FR was already excellent with only two subs after Dirac (or Audyssey + plus some manual phase adjustments). It certainly doesn't sound the same though. Four subs (or even three) just give me more presence/ sense of pressure and the bass comes even more from "all around". The headroom isn't really that important for me as I generally listen to very low volumes (somewhere between -25 to -35 depending on the content) and I don't like to set the bass more than ~5db hot as it doesn't sound coherent to me anymore with more bass boost but the bass still sounds and feels better/more forceful with more subs - even at my volume level.

Edit: ART is still not showing up as available for purchase for my x3800H when I log into the Dirac store at the moment. Can't imagine things not being in lockstep between D&M and Dirac. /s
Firmware version is showing as version 6800-0155-D053-8880 and an Aios 6.0V over UPnP post update.
Looks like they maybe decided to stop yanking our chains and decided Oct 1 was enough ahead of the holiday season. Fingers crossed...
Might even get time this weekend to take it head-to-head with A1 Evo that I've been using.
This just showed up on my 3800:
(should have gotten the first pop up)

Thanks! Just installed the update on my AVC-A1H and at the moment my Marantz Cinema 40 is updating. Now we indeed have to wait for Dirac to release the license

Woow to get the whol bundle $799.00 US, $1207 AUD heaps for just a Room Correction system, wonder if there will be BF discounts.

If it's not in time for BF you may get an introductory offer. I think they did this for DLBC.
Otherwise for Dirac adopters it's more like the boiling frog effect. We've already done the Dirac then DLBC by increments so $299 (with hopefully intro or BF discount) is an easier pill to swallow.

Same here. Worth every penny!
Installed ART and it is amazing with and without subwoofer. But 96 support channels might not be enough for 9.1.6 users.
For me I'm getting the best linear phase, group delay, decay of my whole audio life. This thing is ART.

Sorry no. I bought my A1H in March 2023 and purchased a MultEQ-X license. When DLBC came out I ran both calibrations on my AVR but used Dirac 99% of the time. With ART there is no contest. Audyssey won't be used anymore and Preset 1 will serve for ART for the front seats and Preset 2 for the back row.
You guys are quick. I am not in such a rush and will spend some time traveling so ART might wait till Christmas.
So looks like no bugs and thingy just works? That is really good news.
@SDC anything out there from D&M to read through with respect to 96 support ch limitation? Some models do up to 9.4.6.

I already had measurements saved and just needed to update the firmware, which took ten minutes. No bugs.
