SA "Classic"

(16 reviews) Write a Review

Here at Sundown Audio we take feedback from customers and dealers seriously. With the launch of the SA v.2 woofers we heard a lot of call to also keep the old version for lower depth / lower cost applications — so we did that via the “Classic” SA. Still available in 10s and 12s it is essentially the SA v.1 Rev.3 but with a black motor finish. We even squeezed in an upgrade… the motor is bolted together for enhanced long-term durability!

The Sundown SA series has been our most popular product line since the introduction of the SA-12 in 2009. It was the result of over a year of testing and prototyping until all of our goals and expectations were blown away. The SA series has continually evolved over the years thanks to extensive testing and feedback from our SPL competition Team and our customers but still stays true to its legendary design heritage. It has never failed to prove itself year-in and year-out in every application ranging from daily musical builds to all-out SPL competition vehicles.

When designing the SA series we started out with an FEA optimized motor & coil design capable of 19mm of one-way Klippel verified excursion and just over 33mm of x-mech. This motor & coil setup was then mated up to an extremely robust double-layer Nomex spider with fully tied-on “XL” tinsel leads (84-Strands of Conductor), an SPL competition grade paper cone, and a strong foam surround. The motor also features a large magnet ID shorting ring (faraday ring) to reduce distortion causes by inductance & inductance variation over stroke.

We realized that this still was not enough to meet our goal of delivering the best driver on market in this price range to our customers. To that end we designed a highly optimized voice coil cooling system that has since found its way into almost every other subwoofer we make to this day. This system allows our 2.5″ coil to match and exceed the thermal performance of many competing 3″ coil drivers on the market without requiring the usage of a much heavier voice coil than required for the design. The result is that the SA features the ideal mix of mass & stiffness to give you the best performance in nearly every type of enclosure. All of this hard work and engineering has led to the incredible reputation now enjoyed by the SA series worldwide. We are very proud of what these woofers are capable of and we believe that they are one of the best woofers on the market today hands down for the money.

    No issues with 2 SA Classic12s. They hit hard and the bass is deep. Using a Kenwood kac 9106d with 2 sealed subwoofer enclosures. This is my third set from Sundown. Thanks.

    Sundown SA 12 classic

    Posted by Josh on Dec 20th 2020

    I've went through many, many different audio brands throughout the years and I just keep coming back to sundown. These SA classics have an amazing range. The bass is real tight and loud in a ported box. I was a Skar fan but Sundown is my go to now. And probably always will. Thank you Jake, Derek and the guys for amazing products. Everyone needs to tune into Sundown after dark and Derek's Sundown unofficial videos on YouTube. I can't give you guys a big enough thanks for what you do in the car audio community!!!!!

    SA-12 D2 "classic"

    Posted by Jared Gracely on Dec 1st 2020

    I received my sa-12 the day after I ordered it, shipping was very fast. I built a 1.75ft3 net volume enclosure tuned to 35hz and it sounds amazing and have it running at only the suggested 750 RMS watts. I couldn't hear or see any defects that the yard sale item's are said to have, it's in perfect condition. This is a great price for one of the greatest 12's ever made. Sundown fan 4 life!
