If you are interested I can post 20337’s T/S and these seem to be practically the same units. They are very similar to Peerless 850136 (these Jamos are probably made by Peerless) whose parameters are available, though a bit different than what I’ve measured for 20337. Btw, anyone checked T/S of 850136?

Bogdan, here is the data for two drivers. Please note that the measurement was done with practically new units, after a few hours of burning in.

One driver:

Fs = 37.46 Hz
Re = 5.8 Ohm
Le = 2.43 mH
Vas = 35.28 l
Sd = 235 cm^2 (I’ve taken it as specified for Peerless 850136)
Qms = 7.00
Qes = 0.48
Mms = 40.1 g
Bl = 10.62 Tm
SPL (2.83V, 1m) = 89 dB
SPL (1W, 1m) = 87.7 dB

Another one:

Fs = 35.9 Hz
Re = 5.8 Ohm
Le = 2.41 mH
Vas = 30.55 l
Sd = 235 cm^2
Qms = 7.00
Qes = 0.51
Mms = 50.5 g
Bl = 11.32 Tm
SPL (2.83V, 1m) = 87.7 dB
SPL (1W, 1m) = 86.3 dB
