13.3.1 MEASURING IMPEDANCE OF LOUDSPEAKERS

We will start with a 5" woofer using Sinusoidal, our preferred choice, with the

following Settings (1/24 of octave resolution).

Besides frequency range, which can be changed without side effects, those above

are problem free settings for impedance measurements. We will experiment a little,

pointing out difficulties that might arise. Let’s start with output level, which is a

sensitive topic.

13.3.2 SETTING THE RIGHT LEVEL

The five curves of Fig.13.4 are taken at 5 different output levels, ranging from

10dBu to -10dBu in 5dB steps. The red curve refers to +10dBu, the blue to +5dBu,

the remaining are substantially overlapped.
