| || || || ||Al Lein's Loudspeaker Impedance Tester |
From Howard Tremaine’s Audio Cyclopedia, “As a rule, the impedance characteristics of a loudspeaker are measured in the enclosure used with the system.” Tremaine also recommends using a “400 cps signal” to test full-range speakers.
To make the dial scale, Al taped paper around the pot and marked it with pencil.
