Paradigm Ultracube 12 Active Subwoofer
When it comes to compact subwoofer design our UltraCube™ Series breaks new ground. From their proprietary advanced Class-D™ amplifiers to their very high-power drivers, everything about these little cubes is optimized for high-performance, including their sleek, acoustically inert enclosures. Power! Impact! Extraordinary refinement! Remarkable musical finesse! The UltraCubes deliver it all! A completely unprecedented accomplishment in subwoofers of such compact dimensions.
• Auto On/Off
• Subwoofer Level
• Subwoofer Cut-Off Frequency (continuously variable 40 Hz – 150 Hz)
• Sub/Sat Phase Alignment (continuously variable 0° to 180°)
• USB Port/PBK Interface
• Line-level Inputs
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.
Acoustically Inert MDF Enclosures help limit unwanted panel resonances and vibrations for clean, tight, extremely accurate bass performance.
