Audiophile midrange driver with Sapphire diaphragm.
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)
- Ultra hard 120mm ceramic cone (Corundum / Sapphire)
- 173mm diameter chassis with protective grille
- Vented pole piece, spider and voice coil former
- Extended response 80Hz - 3.2Khz
- Underhung motor, Titanium VC former
- Neodymium magnet system
- Very low distortion
