Sundown Audio SA6.5SWD2 SA-Series 6.5" 200W Subwoofer 2 Ohm
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. Our customers have been in love with the incredible performance per dollar since their launch in 2017.
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!
