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)
|Resonant frequency (fs)||57Hz||DC resistance (Re)||6.61Ω|
|Mechanical Q factor (Qms)||3.75||Power handling||120W|
|Electrical Q factor (Qes)||0.26||Sensitivity (2.83V/1m)||93dB|
|Total Q factor (Qts)||0.26||Chassis diameter||173mm|
|Equivalent volume (Vas)||15.5L||Cutout diameter||145.6mm|
