1.inverted polarity
2.normal polarity
3.0 deg responses
4.step response from#2 picture

aaaand its a no go.

without delay this is just an PA xo, natural voices sounds distant.
tried both tweeter polarities and even electronic music aint as good as it is on my active setup

bolt pattern is straight on to F1 holes, crossing tpl 5770hz
this way around its more beaming sideways than midrange.

Legis said that there might be diffraction issues on F1 stock tweeter waveguide, next im gonna to try add damping on mouth

yeah tpl is way cleaner than b&c de25

i have plans to extend jbl cinema horn 8cm, stock horn starts 143mm2
extend part is 50mm2 to 143mm2, so mouth similar size to inlow 135hz horn

driver maybe phl 1130 or audax, bms 5" or 6" has been on my eyes too

been listening funktion ones, i have to call Legis to tell how it is

old cinema set had more exact listening spot opposite to funktion ones, you really had to move that last 3cm sideways to get it right, its not necessary with f1 and it is really beaming from 1k-5770hz, i think its odd
