hello,
i think the xo-frequencies should be known before starting to model thousands of loudspeakers. the freqs will impose the woofer and driver sizes
and from there we could start to develop. the frequencies should be chosen in a musical way of arguing, and not in terms of truckspace, driver-availabilty
and so on. i would suggest in a 4 way system: 70/80Hz, 350Hz and 3k5.
the components could be 18", 12/15"(x2), 8"(x2), 1", which leads to double 8"1"desiign as does funktion one and centauri (very nice design though, centauri).
I am convinced that 120 Hz is not the right way, if we want it really well and loud, we need four bands, bass lo-mids, high-mids, and highs.
finally very easy
cheers
