Hello,

First, I would thanks David McBean , for the modification of his excellent software Hornresp in order to support horns calculated by my method.

Then, for those who want to simulate the response of a horn loaded by a TAD TD2001 compression driver, here are the best estimated parameters values I could find.

Some of them were given in Kinoshita's paper in JAES I estimated others from my own mesurements and specifically using the impedance curve I obtained on a Jerzual J321 horn bult by my friend Marco Henry.

Ang = 0,5 x Pi radians
Eg = 2,83 volts
Rg = 0,00
FTa = 179,71 degrÃ©s
S1 = 2,26 cmÂ²
S2 = 2838,86 cmÂ²
Lec 51,10 cm
F12 = 320,00 Hz
S2 = 0,00 cmÂ²
S3 = 0,00 cmÂ²
L23 = 0,00 cm
T = 0,80
S3 = 0,00 cmÂ²
S4 = 0,00 cmÂ²
L34 = 0,00 cm
F34 = 0,00 Hz
S4 = 0,00 cmÂ²
S5 = 0,00 cmÂ²
L45 = 0,00 cm
F45 = 0,00 Hz

Sd = 18,10 cmÂ²
Cms = 1,60E-04 m/N
Mmd = 1,60 gm
Re = 6,30 ohms
Bl = 7,20 tesla.m
Rms = 2,72 newton.sec/m
Le = 0,06 millihenrys
Nd = 1 (single driver)

Vrc = 0,14 litres
Fr = 40,00 rayls/cm
Vtc = 0,81 cm3
Lrc = 2,70 cm3
Tal = 1,00 cm
Atc = 18,10 cm3

If a multielements horn has to be built, one can add as a first element a conical element with S1 = 2,26 cmÂ² ; S2 = 5,07cmÂ² and a length of 6,50cm.

Remark 1: I don't know why I obtain an error message when simulating the directivity of a horn calculated by my method. I probably do something wrong...

Remark 2: I would suggest for a further version to allow T value larger than 1.

Best regards from Paris,
