In Reply to: Is calculations of L-pads based on "nominal impedance" or Re? posted by Peter K on March 29, 2006 at 00:56:55:
If you want to do it right, you have to consider actual impedance. Your padding values will not just set attenuation but will also affect the Q of the circuit, which will adjust an amount of peaking or damping. The impedance curve of horns has ripples near lower cutoff, and these can be quite severe. When properly setup, the attenuation resistors will smooth these ripples and make overall response better.
