SA v.2 12 Dual 4 ohm adds 1000w rms to the power rating!

Since 2009, the Sundown SA series has been our most popular line. What better way to make a new version 2 than to upgrade everything? Using a larger, more powerful motor, Sundown Audio maintains the perfect balance of the original SA series while increasing the power handling to 1000-watts RMS.

Sundown Audio SA series 12 Subwoofer History

Sundown Audio began with a FEA optimized motor & coil design capable of 19mm of one-way linear excursion by 70% BL and just over 35mm of x-mech. An extremely robust double-layer spider with fully tied-on & doubled-up "XL" tinsel leads (84-strands of conductor per lead) was mated up to the motor and coil setup, with a competition paper cone and a strong foam surround. The motor also has a large ID shorting ring (faraday ring) to reduce distortion caused by inductance & inductance variations over stroke.

From the original SA series, the voice coil cooling system was improved by Sundown. Using this system, our 2.75′′ coil is able to match and exceed the thermal performance of many competing 3′′ coil drivers on the market without requiring the use of a much heavier voice coil than is needed by the design. The SA series is characterized by the perfect balance between motor force and mass. With extensive testing and optimization, we have maintained that delicate balance in the v.2.

After that, Sundown Audio borrowed the new frame, aluminum surround clamps, and aluminum vent rings that we created for the U-Series to further enhance the SA's performance and reliability. You can think of it as the little brother of the U Series at this point.

If you still prefer the original, legendary SA series, we have re-launched it as the "Classic" and it will be produced in tens and twelves.

This 18-inch model features a larger motor than the SA-10/12/15 v2 at a full 205mm diameter and a 60mm magnet stack height. The top plate is also thicker in order to more effectively move the higher mass 18″ soft parts. It has a large 234mm diameter spider pack for very high mechanical stroke capacity. It utilizes the same 2.75″ coil as the other SA v.2 series for a 1000-watt RMS power rating.

List of upgrades compared to the v1 SA series (Rev.1,2,3):

1) Magnet outer diameter increased from 180mm to 190mm

2) Magnet slugs increased from 25mm to 27mm in height (total 4mm more height)

3) Motor structure fully bolted together with 3x M6 bolts (eliminates the possibility of motor shifting)

4) Top-Plate “Slits” implemented as with the X and Z series. Increased cooling & reduced distortion.

5) Improved gap venting — more / flared gap vents.

6) Improve pole-vent design — smoothly flared on both sides.

7) Coil increased from 63.5mm (2.5″) to 70mm (2.75″) in diameter. Higher thermal capacity.

8) New “U series” style cast-aluminum frame for taller cones (more x-mech both top-side from cone to spider and bottom from spider to top plate)

9) Aluminum cast gasket to bolt-on surround.

10) Aluminum cast vent ring to enhance thermal transfer from the motor to the frame.

11) Standard with double “XL” leads and “bolted-on” spider

12) Larger and thicker surround (same tooling as U series).

13) Strongest paper cones we have ever produced… new two-piece mold technique.

14) “Large Flange” dust cap just like our larger woofers. Essentially eliminates dust-cap glue failure.

15) Larger spider diameter on the 12/15″ models (the 10″ retains the same 188mm spider)… 12″ up to ~200mm and 15″ up to ~210mm

16) Improved spider material for longer life.

    Posted by MrKnightRider on Mar 23rd 2022

    First time buying sundown subwoofers always wanted to try some but the price kept me from buying after I did some research about how under rated they are on power they went on sale on down4sound for a price I couldn't refuse best decision I ever made got some other subs I needed to replace took a chance on these I love em with the warranty you have with these I should have switched a long time ago

    Exactly what I was looking for

    Posted by Isaac on Mar 22nd 2022

    Very aggressive, very well made sub. I’ve had a Memphis SR12, a pair of Kicker C12s, and a Sundown E12. This one is the one I was looking for. So awesome to hear this thing get in that 25-35hz range. Highly recommend. Also D4S is killer! Ordered this thing around 10:00pm on a Monday and I was listening to it in less than 48 hours.

    Awesome!

    Posted by Sean McKinnon on Nov 23rd 2021

    This sub is amazing! I have it in a Tru Spec box powered off a 1200.1 Skar amp only running a little over half the subs power rating (still breaking it in) and this thing absolutely pounds! I listen to a lot of different music, but mostly rock/metal and this thing has no issues keeping up with fast paced bass. The lows are insane with rap music too. Down4sound shipped fast and threw in a few extra goodies as well. I'll be making my door speaker purchase here too for sure!
