C173-6-090Highlights:- 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
