For subs just go with a few diy sealed 18” (or even 15”) and don’t think twice about it. With DSP you can drop them down as low as you like. Your eardrums with bounce out of their gap before the voice coils do.
For mains just grab a pair from the JBL synthesis line, they have a nice new model coming out next month.

In computers, "Ghosts in the Machine" are blamed for the death of certainty.
In coaxial speakers, "Ghosts in the Cone" are blamed for the death of clarity.
Does the Beyma 8CX300Fe coax driver deliver sound that is "Clean.. Clean.. Clean"? Or does the stacked tweeter horn generate cone air pressure reflections? "Ghosts in the Cone"

Linesource, it could be dealed with... thanks do dsp and lots of measurements. At least this is what Fulcrum acoustics does with his algorythm ( which you can find 'licensed' to Presonus in it's Sceptre range). But yes it is true coax high end is compromised somewhat. This is one of the compromise using them. That said the plus overcome this to me.
I don't know the Beyma in question so can't talk about it. That said it seems Audiothings choices are limited due to his area.
If Bms is availlable ( which seems to be the case from what i understood) i would go with them:
Given the xover frequency i talked about you are well positioned to use a 'tannoy style' coax as the xover will lessen the mid membrane motion to insignificant levels ( so lessen the main concerns about the principle). They sound goods and are robust from what i've seen.

Apologies for disappearing for a while. Many thanks for the replies and PMs.
I have found a designer I want to work with, at this time, I am not looking for another designer.
I will reply to the PMs very soon. Sorry again, for the delay.
Lojzek, somehow I had ignored that I have gained a lot from this forum and not contributed anything in return. I will address this soon, and I thank you for bringing this up...
The person I have chosen to work with brought up the advantages of working with a larger driver, just as you did. I will almost certainly go with his recommendations.
also krivium, thank you. You seem to have a clear understanding of where I come from. These pages from my website about loudspeakers and rooms and non-environment rooms almost echo the points you have made...

Why does it have to be kept within PM, wouldn't it be better and fair to keep the project going as open source and you can donate those funds you had in mind to diyAudio instead?

Audiothings what freq do you plan to cross your coax? Because 110db continuous will be a challenge for an 8" even crossed at 150hz ( could work better around 250hz with 'steep' ( higher than 18db/octave/third order) slope xover however). Have you already worked the Center to center spacing of coax and woofer too? It will help define xover freq too in case of Mtm.
I would upsize to 10" or 12" for this kind of spl..

Audiothings - if you run into any trouble with the Hypex software, PM me, or contact YSDR. Honestly I doubt you will need any help. I found the Hypex HFD software easy to use.

Hi Audiothings,
Well after reading your site ît seems we share some experiences in our professional background.
And as i spent a lot of time in some Hidley's room ( 4 differents 'hemi-anechoic' rooms mainly (mid 70's designs) and a N.E. i experienced for some weeks) and developped a kind of fascination about them i digged as much as i could to understand what make them differents from other control rooms i known (and it help when you are in a position where you can watch what is hidden behind the black fabric). Despite the fact this is not the kind of approach i liked the most: I think they steal to much energy from loudspeakers and it can be dealt with differently. 😉
But i suppose this is not the place to start a discussion of pro and cons of pro studio acoustic treatment approach.
Will send you a pm in near future.
