therefore since which frequency diffractions become a solvable problem ?
i am thinking to a 500Hz cross between the bass bin and the head unit
Why? Emissions from push-push and front-firing are both omnidirectional and as long as youdon’t put anything too close to the woofer, essentially the same below say 300 hz.

Sign of a poorly aligned reflex or BBC style box walls that don’t really do the job.
i sold the KEF 105s, i thot them kinda constiopated, B&W 801 was better.

Good morning and thank you again I have a difficult situation as i have to place the speakers in corners
and as the room is not that big i have to place them quite close to the side and back walls I am sure this will increase the bass response
i will have to check Maybe i will even need a equalizer
unfortunately this is the current situation
of the most classic britich speakers the only ones that i realyi liked (very much indeed) have been Tannoy and not all The ones with paper cones
i remember a huge pair of grey monitors with a plastic woofer They were impossibile to drive System DMT 12
they were beast at 26kg each But the woofer sounded sluggish I guess they are current hungry ?
thank you I like the concept I do not know the drivers They say that they shine with classical music
soundstage should be very well developed in the 3d
When i see a tall speaker i immediately think to cut it in the middle and make it in two pieces
i must have a Robespierre attitude Decoupling the head from the body
you mean the 105 and 801 ? if so very good indeed
i can guess that diffractions can be bad for FR and also for soundstage reproduction
however i dont think that two cabinets are really needed for mid and tweeter They can share the same enclosure
About materials for building a cabinet...
May be of interest.

haha.. this made me crack up, you are on the right path. :)
Good morning and thank you very much for the very interesting link
maybe in the end a thick and heavy solid wood and a certain bracing could be the most straightforward answer
a structure like the Matrix by b&w as far as rigidity is concerned
the bass bins show a good behaviour (i still do not understand why they not place the accelerometers on the front baffle)
https://www.stereophile.com/content/bw-matrix-801-series-2-loudspeaker-measurements
with sufficient rigidity and mass
above all a wood that remains structurally stable over time
it is true that there are fiberboard cabinets from 50 years ago that still work if kept properly
there remains the problem of the equipment to work the wood
when I see the workshops of certain diyers I feel a strong envy and they seem to me to be real industrial contexts
I am sure that a professional would charge a high price even for just two cabinets for the woofers especially if with the bracing to be done
I think even 400-500 USD/each if anything with the material I will ask anyway
I should find some 801s with the woofers broken and even without heads
their bass cabinets should be very good
