Sundown Audio SA Series 8" Dual 4-Ohm Voice Coil Subwoofer 1000W Peak SA-8v.3

Proprietary FEA optimized motor design engineered just for the SA-8 v.3 which features a large aluminum faraday right for low magnetic and inductive distortion levels. This motor is mated to a custom tooled and patented frame which allows for a larger spider and superior clearances to nearly any other 8" woofer. Features a full 16mm of Klippel verified one-way linear excursion and mechanical capacity in excess of double the linear limits to ensure that mechanical failures are nearly impossible. We employed a solid pole-piece to maximum magnetic flux in the motor. In order to reduce mounting depth we did not use a vented frame spacer; instead, drilled vent holes around the basket base. Also added sixteen chamfered gap vents to the back plate to keep the high-velocity air flowing over the voice coil.
