- Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
- Very rigid mica-paper composite cone to ensure piston motion at high levels for reduced distortion
- Low-loss suspension (high Qm) for better reproduction of details and dynamics
- New reinforced die cast aluminum chassis with optimal ventilation and increased stroke
- Large motor with 2” voice coil diameter for better control and power handling
- Built-in aluminum field-stabilizing ring for reduced distortion at high levels
- Vented center pole with dual flares for reduced noise level at large cone excursions
10.75" Ultra-High Performance Subwoofer Unit
When nothing but the most extreme in bass output and performance is required.
Very low distortion from below 20 Hz
FEATURES
