C173-6-090 Ceramic Midrange
Highlights
7 inch midrange with tissue suround with high efficiency for 3 way designs.
Large sized voice coil with 55mm titanium voice coil former for high midrange resolution.
Big underhung 120mm Neodymium magnet system for very low distortion.
Anti-resonant cutout fills in the ceramic dome provide high damping of the 5 kHz dome resonance.
Closed Box design 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)
