The C173-6-090 is a midrange drive unit featuring an ultra hard ceramic (Sapphire) 120mm cone in a 173mm diameter chassis.

Precision cut apertures in the ceramic diaphragm provide critical damping of the 5 kHz cone resonance.

An underhung motor design featuring a 55mm titanium voice coil former and large Neodymium magnet yield high midrange resolution.

This exotic unit is designed to operate in a sealed enclosure, here are some example parameters:

Vb: 2L, -13dB @ 80Hz, F-3dB: 160Hz, Q: 0.71 (typical)

Vb: 4.5L, -10dB @ 80Hz, F-3dB: 170Hz, Q: 0.50 (clean transient response)
