pretty much same results if its handmade british midrange or 1992 toyota camrys door speaker
maybe i someday buy jbl waveguide on top too, POOH has one too

passive xo simulations
1. this how it is, 99mm acoustic difference between drivers
2. tweeter polarity inverted
3. 99mm delay added to tweeter
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
Silver modeling clay, trying to improve F1 tweeter horn for better dispersion
it dips on 0deg above 7k
did not took full polars, atleast 0-30deg its much better, doesn´t wrap as much as stock
purple is stock, others left and right
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

about the manifold, or mannifold may i say
8cm thick easily fileable mdf
drill holes to angle where path lenght match
this radial type interests me too
An externally hosted image should be here but it was not working when we last tested it.
went to dual channel fft
whoaa!! now i think car dsp is easy to tune, just keep other pc´s ARTA sniff live pink noise phase and tune dsp with other laptop
Now thing started to move on. modeling clay to get easy 100% custom shape.
some measurements for reference before clay, i hope i can keep my microphone setup untouched so measurements are comparable.

mouth is too large, maybe over 70cm2, i wanted it to be 50cm2
and path from cone to mouth is uneven
just wasted couple of hours of my life again.
path from voicecoil and outer went uneven.
well i have to check it out again from scratch
