Hello and thank you so much
Impressive ... not in the good way.
It is a pity anyway.
Maybe a better way to limit dispersion of woofers is the one depicted ?
I want a controlled dispersion speaker even if this will limit hugely the sweet spot ... i listen music alone usually.
And i would like to limit as much as possible room acoustic treatment
Thanks a lot indeed again for the very valuable advice/help.
Kind regards,

Limiting the dispersion of woofers simply requires a very large horn mouth or baffle, as in 1 wavelength across. Since that's 11 feet at 100Hz and even then just results in half-space radiation it's not a practical endeavor. Cardioid bass arrays work, but they're not all that practical for a home environment.
Thanks again and i see ... not very practical indeed.
Not an option for me for sure, as i am already struggling to get some more space for the system at home.
Kind regards,

Narrowing the dispersion of low frequencies isn't a worthwhile goal, since you'd end up with something that doesn't exist in live performance or in the recording studio anyway. Cardioid arrays exist for the purpose of reducing environmental bleed through, especially in outdoor concert facilities.
