Simulations in Pass Article

[Michael Rothacher]

Mr. Pass:

What did you use to produce the simulations in your article on current source amps and full range speakers? Also, how are the values for the simplified speaker impedance model derived from the driver spec?

Thanks fo your time

Mike

I used Micro-Cap (the old Dos version).

The driver models were fit trial-and-error against impedance
curves measured by an AP System 1.

Ah, cool. Thank you.
