Sundown Audio SA Series 6.5" Dual 4-Ohm Voice Coil Subwoofer 400W Peak SA-6.5SW

This Listing Includes:

• (1) 6.5" Dual 4-Ohm Voice Coil Subwoofer 400W Peak

The SA-6.5SW was created to achieve extremely high performance at less than 4†of mounting depth (3.8†to be precise). Rest assured that even with the limited depth the SA-6.5SW lives up to the reputation of the SA series! These little guys will take a beating in TINY ported enclosures. As with several other lines (SLD and SD-4 notably) we used a solid-pole design. This allows the back-plate to rest against the back wall of the enclosure. This further reduces effective depth requirements for this woofer. Shallow depth aside this unit has a full 10mm one-way linear excursion and an x-mech in excess of double that! So there is almost no concern about bottoming out the coil. We also borrowed the hyper-extended pole technique from our larger lines to help prevent coil damage from exiting the gap forward. Furthermore; we even included a magnet ID faraday ring to keep inductive distortions in check!
