Seas 22TAF/G Help needed

[ostry]

Hello!

I am designing shelf speakers using SEAS P17RCY and SEAS 22TAF/G speakers and i would like to simulate my crossover in OrCad (see more there: http://shine7.com/audio/orcad.htm ) but i can't model the tweeter properly because I couldn't find or calculate Qms or Rms values.

So my question is: does anyone has measured values of Rms or Qms of the SEAS 22TAF/G?

Thank you in advance for any replies

regards

Hi ostry,
I checked your datafile for SEAS 22TAF/G (www.seas.no)
http://www.seas.no/Prestige Diskanter PDF/22TAF_GH1283.pdf
and I would model with

mechanical reactance
L2 = 1.4mH
C1 = 14uF
R2 = 12

hope this helps,
take care.

thank you very much dear Inductor, I will try with your values. Mine (calculated) are:

C1 = 21,12 uF
C2 = 0,743 uF
L2 = 0,993 mH
R2 = ? (unable to calculate it without Rms)

once again thanks for your effort

if someone has the measurements of Rms, feel free to post them here

regards

ostry, how is your simulation going?
