How to measure T/S of tweeter?

darw82 · 21st November 2007, 05:32 PM

hi,
In mid woofer/woofer. In order to get T/S parameter, we usually measure impedance in free air, than compare it with impedance in added mass or sealed box.

I was wondering, how to measure the T/S parameter of a tweeter with Speaker Workshop? Should I use the added mass methode?

Thanks.

Why would you want to? T/S parameters are lumped element approximations intended to be used to simplify box design, doesn't cover things like cone breakup. Tweeters usually don't use a tuned box.

Bwaslo,
The T/S is not use for box design. It will be use for crossover design.
I use X-Over Pro 3 from HT Audio to design the crossover.
This program, shows me weird result if the T/S parameter is not input properly.

By the way, the tweeter is Seas H1396

Darw to desigh a crossover you need the Frequency response and the impedance data of the tweeter and the bass in the cabinet you want to use.
