Doing the trick to their A11ms (and i suspect others) and report back.
I don;t want to say too much outside the trhead i haven’t started yet.

Indeed! Nowadays though it's a common 'frame of reference' when folks mention HT, watching movies, musical concert, etc. DVD/BDs, but not recommending designing for it per se, only needs to account for the significant extra eff. and/or power required for such a big room, long listening distance.
IOW working it backwards, let's assume the driver can handle the THX 105 dB peaks/25 W/m with its relatively loud 85 dB avg., then 4 m away it's 105 - 12 = 97 dB peaks/25 W, 85 - 12 = 73 dB/25 W avg., which isn't as loud as some/many? folks watch a TV movie (~76 dB avg. based on various 'HT in a box' specs I saw long ago now), so must (over) drive? them up to 100 W with the associated (potentially audible) added distortion of high excursion.

I thought they were using Ingles....
My wife is a Speaker Monogamist, she only has one pair.
I, OTOH, am a Speaker Polygamist. I got more than a few. After all, I got an Amplifier Harem.

sorry for my newbies questions,
i think i will go for MAOP 10 or 11 ms, i would like to have your opinion for the enclosure,
i suppose frughel xl is better but it's long 54 cm i think and need to be 50cm from the wall, it will be possible (due to WAF) to in corner not be possible too.
i know there is pensil it's not a problem to build something complex if it bring something but i have seen DNA dexware or dna2 give a lower extension to 20hz, i a bit surprise and want to have opinion if you have listen
i see this too: DDBH-T15F-AD-01 from https://sites.google.com/view/low-e...-single-driver/-diy-adjustable-duct-type-ddbh not exactly this model but this enclosure type @nandappe
and this too: https://www.markaudio.com/wp-content/uploads/2023/02/MAOP10.2-TL-1.png

We built the DNA box. It would have burned if we hadn’t found someone who was happy to take them.
The most common box i have seen is the Mar-KenM10T trapezoid, but FHXL or Pensil reach lower. Add helper woofers to the Mar-Kens and you can surpass or equal their bass extenmtion while at the same time releivignb the bottom.
ML-Voigts can be good, but we have not verified Nandape’s. He also seems to be using existing designs for drivers they were not originally designed for.
For the M10 any A10.3 box should work, including the pre-chamber TL of Scott’s you linked. There are more than a few others.

@Pierrick59 My opinionis that better aim for 40hz flat than 20hz. -Unless you listen a lot to church organs. Some elevtronic music goes down to 20ish but will have plenty of bass above🙂Others will disagree.
Cheers!
Cheers!
Standard piano = 27.5 Hz, bass fiddle = 41 Hz, kick drum = 50 Hz, male vocals = 100 Hz, alternative rock = ?, so speaker Fs/tuning ideally needs to be ~27.5 Hz - 41 Hz with the room and where the speakers are located in it will dominate best overall tuning, so IME plan for the lowest as practical WRT driver choice/box size and do final tuning in room to 'taste'. 😉
I won't disagree GM. My main points are that digging deep in the sub department creates problems (fixable yes, but not by most average guys). And spending a lot of effort and or money on a limited budget reaching for the last precious hz could be better spend on making overall better speaker. Sometimes at least.😊

@Pierrick59 here:
My latest fullrange is behind that cloth. Its Phillips
Here are my pc speakers: their identical drivers, and my future dashboard speaker for my Colt. I dont know if I will turn them aperiodic vented or use one or more of the many passive drivers I just got from AliExpress.
Cheers!

With cfa amplifier and little bit eq a Pioneer t-sg1310f sounds pretty high end due to good cone material
The King for me is this 15 inch fullrange but with my aluminium sandwich mod, Fane Sovereign 15 300tc

Yes coloured. So much that friends would surprised say "Oh! That sounds gooood!"
They were driven by small Logitech sub which was perfectly fine in my cramped home office. No sub bass ofc.
Thanks planet I will EnABLe mine too. Im not sure they are suited for EnABLe plus alu so ill save that for others.

I admit I initially skimmed over the room size due to it being stated in square meters. After converting to square feet, I agree 100%. That is a huge room.
