Tonal Profile

The flagship of the line: 100 mm diaphragm, 15 ohms, 100 dB/Vrms. Moondrop quotes the frequency range under IEC 61094 free field and the effective response under IEC 60318-4 - two different standards in one table, worth remembering before comparing its 13 Hz-58 kHz against anyone else's.
