[QUOTE="Buck, post: 8862040, member: 591582"] Re is DC: “Measured in [URL='https://en.m.wikipedia.org/wiki/Ohm']ohms[/URL] (Ω), this is the DC resistance (DCR) of the voice coil, best measured with the cone blocked, or prevented from moving or vibrating because otherwise the pickup of ambient sounds can cause the measurement to be unreliable. Re should not be confused with the rated driver impedance, Re can be tightly controlled by the manufacturer, while rated impedance values are often approximate at best.” [URL unfurl="true"]https://en.m.wikipedia.org/wiki/Thiele/Small_parameters[/URL] I have “8 ohm” impedance towers that read 4 ohms or so DC-wise.
