Interesting that they say: 25 - 40m² per sub. So that means I need just one sub. Can I place it next to either of the speakers? I can probably place it next to the right one.
Moving away from box speakers: Diesis Audio vs Avantgarde Acoustic?

One sub is enough, it will easily fill the room. Double subs in the middle work best, so you have the least amount of side wall reflections. Of course it also works next to the speakers but in a line with the speakers, then you don't have to change the phase response much.
Exsample
I only had about five minutes to spend in the room, primarily due to time constraints, but during that brief period, the audio quality was impressive. Another room that caught my interest, though I couldn't explore it further, was Lorenzo Audio.
Another room that left a strong impression on me was Martion Audio. This horn-based system, which incorporates DSP, delivered incredible clarity, smoothness, and dynamics.
If you go for an Avantgarde speaker, you are most unlikely to need subs as their bass is very good. The Uno SD uses a single 10" driver, whereas the Duo SD uses a single 12" one. Adding subs inevitably adds CCCC (complication, clutter, cables and cost), so avoid them if possible. I doubt you'll be hankering after more bass with either of these speakers, as their built-in back-panel adjustments allow considerable control over XO frequency, bass level, etc.
If you need more "room correction" adjustment, the AG's performance can be measured (no mic provided) using REW or similar and the AG software allows adjustments to the standard straight-line response according to the in-room measurements taken You can ask your dealer or national distributor to do this somewhat complex job if buying new - they'll have a comprehensive kit of measuring gear - although I doubt you'll need this. Thus, there is no need for the likes or Dirac or RoomPerfect. Another advantage is that the AGs bass driver is powered by its own amp and DSP is only applied to that driver, so the rest of the signal reaches the other drivers unmolested by any unnecessary signal processing.

It's not about which concept plays deeper. It's about control and the lowest possible distortion in the bass. The more deflection a bass driver has to make, the greater the distortion. If you distribute the bass signal to several actively controlled drivers, as in my example photo of 2x 16" woofer + Geithain 3way with 16" speakers, you have a more even sound distribution in the room.
The deflections of individual drivers are reduced and distortion is lower - it simply sounds cleaner. In the bass range, there is no substitute for membrane surface area, as the old saying goes with cars, there is no substitute for engine capacity except for more engine capacity.
P.S
I use 4×15" woofer in a 40 square meter room, but it is still not enough, it can be even better.

Interesting, Todd! Do you think that switching to a fabric dome is the reason that the historical brightness/edginess issue some audiophiles (including me) have had with AG has been ameliorated?
Can you fly to Germany? Avantgarde is in Frankfurt, and Cessaro is in Hüttenberg. Hüttenberg is only about 60 kilometers (37 miles) north of Frankfurt.
Jeff Catalano told me that SE is a mild evolution of original Opus.
I would put subwoofers on a ham sandwich.
A couple of years ago I did not want Keith to consider the Opus without considering the subwoofers to be mandatory. They seem like really nice subwoofers which can be used in a lot of non-Cessaro applications.
I don't think I have ever heard the Uno SD. Even if I had ever heard the Uno SD previously my answer to your question is that I have no idea whatsoever, as I would never have heard both speakers in the same system in the same room playing the same recording to make a valid* comparison.
*As opposed to the typical audiophile rationalized decision based on many varieties of analytically invalid and methodologically invalid "comparisons."
I suggest Thrax Lyra SE with sub Hades,i have in second system,pricec list 37.000 euro,for me absolutly the best at any price also 4/5 times more
Another very good choice for me is WB Endevour with new IGX sub
I cannot image better speaker over these.
I have AF3P with Opus 1,CH PI.L! X1 like you
Lyra little on the bright side,Mephisto little on a dark side,so will be a perfect match,FOR ME

My main speakers feature 4 x 12" drivers between them, but I have another 4 x 12" drivers in subs. These extra subs make just about zero improvement in my 945 sq ft room, so I am planning on selling them. I prefer to limit cone diameter to 12" (with large diameter voice coils) as my experience with larger ones is that they can be rather "flabby", as the outside part of the cone has difficulty keeping up with the voice coil at the higher frequencies within the bass range. A very large voice coil helps of course, but many 15 or 18" drivers feature coils of 3 or maybe 4" only.
I would highly recommend while pursing the horn route that you understand the minimum distance from speaker to sweet spot for adequate driver to driver integration.
For such a large room you need the tyrexxx from betonart audio. Then it makes a difference, promised.

Those are true monsters! Thanks, but no thanks. I'm not into home theatre nor cathedral organ music and I wouldn't want to clutter my room with those (can I say ugly) beasts. I am more than happy with the bass from my dinky-little 4 x 12" drivers powered by their 2000 watts

In real life they look ok. Uncompromising bass, never heard before.perfect match with avantgarde
I enjoyed the Lorenzo but not for what they cost. I distinctly remember the Nika system because it was a speaker high on my interest list…the system didn’t sound good to me though.
I can confirm that the Opus 1 + sub sounds excellent…in fact it’s the only Cessaro I truly think sounds great! Never heard without the sub, so hard to say if those alone can do reasonable bass if you can’t fit the sub.
Diesis sounds great but, being dipole, they need a decent amount of space behind them. If you can’t accommodate them they won’t work optimally.
