Test Bench: Faital Pro 6RS140 Midwoofer / Midrange
Voice Coil, July 2019 · Read by Bits 29 Sep 2026
Measured with LinearX, Klippel, Loudsoft and SoundCheck rigs. The response is smooth to about 5.5 kHz and peaks near 7.6 kHz as it rolls off, and an aluminium shorting ring keeps the inductance almost constant. Its parameters track Faital’s except Vas and Xmax. Two samples matched within 0.5 dB.
