Sundown Audio 8 inch SA Series V3 Subwoofer:

The  Sundown Audio SA 8 v.3 represents the pinnacle of low distortion ported box 8-inch subwoofer technology. Every piece of the SA-8 v.3 has been custom-tooled with the utmost performance and lowest distortion in mind. We started with a proprietary FEA optimized motor design made just for the SA-8 v.3 which features double faraday rings just like its bigger brothers. This motor is mated to a custom tooled and patent-pending frame which allows for a larger spider and superior clearances to nearly any other 8" woofer on the market today. The spider itself was custom tooled to achieve a very even compliance curve and also features double, tied-down tinsel leads to handle incredible amounts of power. The  Sundown SA 8 v.3 also 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.

The standard Sundown SA 8 v.3 features a 4-layer copper voice coil for the most possible low-end extension. We do offer SPL models with lighter coils and even "extreme SPL" models with harder spider packs and other impedance configurations (these must be custom-built).

    Bought one of these and put in a custom box ported box. Sounds amazing. Even being a SPL sub it reproduces music very well. Great sounding sub. Putting 450 watts on it and it seems like it can take much more.

    Stout little 8!

    Posted by Anthony S. on Sep 14, 2020

    These little 8's are nuts. Way beefier than I expected, and they weigh a ton. 25lbs is no joke for a little sub. I have (4) of these in a ported box and they get low and tight. Sounds amazing, not quite as boomy as a bigger sub, but the low's will kick you in the chest in a proper box with enough power. Couldn't be happier with the subs, and with the D4S shipping and customer service!

    Beyond impressed

    Posted by David on Oct 30, 2018

    This sub ain't no joke. Built a box .75cu/35hz and its slapping like 2 12's easily. Perfect with the 1100.5. Jonathan's delivery is super fast ! appreciate that!
