Flare freqency

Can anyone tell me if the "flare freqency" mentioned at this site: Single Driver Website
is the same as the Fs value for a driver.
Best regards

It's the tuning frequency of the horn. You can set it to any frequency you like, providing you design it properly to achieve the intended goals.

Hello,
If you have AH, AM, l,
k still lacks the flare rate:

ln (AM / AH) / l = k

K VALUES:
0.37 ~ 10 Hz
0.55 ~ 15 Hz
0.7 ~ 19 Hz
0.9 ~ 25 Hz
1.1 ~ 30 Hz
1.3 ~ 35 Hz
1.48 ~ 40 Hz

Important is the blind and real part of an expo horn:
example if you want 40 Hz you must take k=20 Hz
=1 oktave over k the horn plays.

look my constructions and measurements on my HP
