Proprietary Advanced High-Power Class-D™ Switching Amplifiers provide truly massive amounts of clean, high-current power as well as ultra-low distortion. Power output is 1950 watts Dynamic Peak/650 watts RMS.

Advanced Down-Firing Mineral-Filled Co-Polymer Polypropylene Cones with RCR™ Resonance Control Ribs. Superior cone rigidity and the high internal damping properties of polypropylene ensure well-extended bass response with impressive articulation and ultra-low distortion.

Oversized Dual Magnet Structures generate exceptionally strong magnetic energy in the gap. Advanced suspension ensures wide peak-to-peak excursion with superb control.

Proprietary AVS™ Airflow Ventilation System Cooling conducts heat away from the voice coil.

Dual Balanced-Plane High-Velocity Passive Radiators. Solid, stable, and free from unwanted resonances and vibrations, the passive radiator design assists in providing the exceptionally deep bass these compact cubes deliver.
