  Signature Series
 
  Signature Servo Bass Driver
  Next-Generation Mineral-Filled Co-Polymer Polypropylene Cones with RCR™ Resonance Control Ribs  
  High stiffness design is intrinsically low in distortion. Cone is able to respond instantly to the starts and stops of even the leading edge of bass notes.  
  Bifilar 8-Layer High-Temperature Aluminum Voice Coils  
  Wound on a high-temperature Apical& trade; former in an oversize 8-layer bifilar configuration. Provides greater stability and support during extended cone excursion.  
  High-Pressure Die-Cast Aluminum Chassis  
  High-Pressure Die-Cast Aluminum Chassis controls flexing and ringing, and since aluminum is non-magnetic, eliminates stray magnetic losses.  
  Proprietary AVS& trade; Airflow Ventilation System Cooling  
  Conducts heat away from the voice coil. Massive built-in "zig-zag" ribs increase heat dissipation surface by 40%, providing forced-air cooling during large musical transients and chassis convection cooling at all other times.  
  Massive Extruded Aluminum Ventilated Center Heatsink  
  Provides internal forced-air cooling to drive heat away from the high-velocity low-turbulence pole piece, thereby increasing power handling and reducing distortion.  
  Dual Spiders and Oversize Long-Travel Suspensions  
  Dual Spiders and Oversize Long-Travel Suspensions allow for extreme cone excursion while maintaining exacting control over cone movement at all times.  
  Massive Computer-Optimized Magnet Structures with Balanced Field Geometry  
  Massive 13-kg (29 lb) magnet structure generates an enormous magnetic forcefield while minimizing inductive distortion.  
  Proprietary Voice Coil Wire Guide with UMD& trade; Ultra-Rigid Mounting Domes  
  Proprietary Voice Coil Wire Guide with UMD& trade; Ultra-Rigid Mounting Domes provide precise and stable accelerometer mounting. Wire guide allows large-gauge wire connection to the voice coil with unrestricted cone movement. Rigid wire guide cap stiffens the cone/voice coil interface.  
  Superior Instrumentation-Grade Accelerometer  
  High sensitivity and ultra-low noise (below -100 dB) designed to withstand the driver's extreme changes in motion-over 100 times the force of gravity. (Rated in excess of 150 g's.)
