Vibration-Cancelling Design Architecture (see above tab, VCDA) is only part of the story. There’s still no replacement for displacement: In a small, compact form factor, six 10˝ drivers in SUB 2 move more air than a pair of 15˝ woofers! SUB 1’s six 8˝ drivers move as much air as two 12˝ woofers. The other part of the story lies in the cutting-edge design of the bass drivers:

Mineral-Filled Co-Polymer Polypropylene Cones. A 30% mineral content has introduced additional cone stiffness for a measurable increase in repeatability and consistency. Response is instantaneous—low, loud, fast and tight, unveiling layers and layers of low-frequency detail, with consistently perfect pace.

Overmolded NLC™ Non-Limiting Corrugated TPE Surrounds and Nomex® Cloth Spiders. These extreme low-density NLC™ surrounds on SUB 1 were FEA-optimized and overmolded onto the cones in house. Ten times more effective than standard thermoplastic elastomers in damping vibrations and resonances, the corrugated material works in tandem with our Vibration-Canceling Design Architecture to ensure not a hint of distortion exists, even at peak-to-peak excursion (almost 2˝ / 50 mm in SUB 2!) and full-on output.

RCR™ Resonance Control Ribs. NLC™ surround technology was not required in SUB 2 since the six 10˝ drivers already allow for larger surrounds. The cones’ resonance control ribbing simply reinforces the new VC design architecture. As in SUB 1 cone excursion on each driver is extreme.

3˝ (76 mm) 10-Layer Long-Travel Aluminum Voice Coils. Wound on high-temperature composite polyamide formers in an oversize configuration, the coils provide exceptional stability and support for the extremely high cone excursion.

High-Pressure Die-Cast Aluminum Chassis with AVS™ Airflow Ventilation System Cooling. Large built-in ribs increase the heat dissipation surface providing forced-air cooling during large musical transients and chassis convection cooling at all other times. CNC-machined to ensure a precision fit.

Magnetic Pole Piece: FEA-optimized, tooled to support the extreme excursion.

Extruded Aluminum Center Heatsink. Provides internal convection and forced-air cooling to wick heat away from the high-velocity low-turbulence pole piece, increasing power handling and reducing distortion.

Computer-Optimized Ceramic (Hard Ferrite) Magnet Assemblies with Balanced Field Geometry. Using Finite Element Analysis, the magnet structures were optimized to yield the most powerful output in a Signature subwoofer to date. Transient and phase-response are exceptional with superb power handling and output linearity.
