here's 4 inductors marked 2.4->3mH (just got the Electra-Print so not heard it in a system)

Madisound 3mH bar-core steel laminate
Solen 10awg 3mH air core
Klipsch 2.4mH E-core from K-horn
Electra-Print 2.5mH (reads ~2.8mH on WT3) EI - core about the same size and mounting centers of the Klipsch unit

dcr for the E-P came in around 0.065 ohm on a couple of runs - WT3 sometimes changes
