High-Pressure Die-Cast Aluminum Chassis |
|
|
| |
Controls flexing and ringing, and since aluminum is non-magnetic, stray magnetic losses are eliminated. |

AVS™ Airflow Ventilation Cooling System and Huge Heatsink Fins |
|
|
| |
AVS™ Airflow Ventilation Cooling System and Huge Heatsink Fins provide forced air cooling during extended cone excursion and convection cooling at all other times. |

Mineral-Filled Co-Polymer Polypropylene Cones with RCR™ Resonance Control Ribs |
|
|
| |
Both sides of the cone are ribbed, providing superior stiffness with low mass and excellent internal damping for tremendous freedom from unwanted resonances and distortion. |
|
|
|
|
|
| |
Dual Spiders and Dual Ultra-Long-Travel Suspensions |
|
|
| |
One progressive and one linear, promote greater cone excursion while maintaining exacting control over cone movement. |

Dual Balanced-Plane High-Velocity Passive Radiators |
|
|
| |
Dual Balanced-Plane High-Velocity Passive Radiators provide extended bass response with very low distortion. Solid, stable enclosures, unhampered by vibrations or resonances, contribute to the clean and articulate bass performance. |

Oversize 4+4-Layer High-Temperature Aluminum-Wire Voice Coil |
|
|
| |
Wound on a high-temperature Apical™ former, with advanced high-temperature coating and twin-layer bifilar configuration for greater stability and support during extended cone excursion. |
|

Proprietary Voice Coil Wire Guide |
|
|
| |
Proprietary Voice Coil Wire Guide allows large-gauge wire connection directly to the voice coil for unrestricted cone movement while eliminating the possibility of "cone slapping" of lead-in wires in this high-excursion application. Unique rigid wire guide cap stiffens the cone/voice coil interface. |

Massive Computer-Optimized Magnet Structures with Focused Field Geometry |
|
|
| |
13-kg (29 lb) magnet structure on the Seismic™ 12 and 8.5-kg (19 lb) on the Seismic™ 10 generate an enormous magnetic force field while minimizing inductance distortion. |

Massive Extruded-Aluminum Vented Center Heatsink |
|
|
| |
Massive Extruded-Aluminum Vented 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. |
