2 Sundown xv3 d4 and SALT-4

The X v.3 series is the entry into the Sundown Audio “ultra-high excursion” suspension and frame designs. They all feature our custom tooled and patented frames (US Patent Numbers D691596, D691597, D691598, and D741841).

We mate these new platforms to a triple stacked 225mm (8.86”) diameter motor structure featuring a hyper-extended pole and extreme clearances (allowing up to 4″ p-p travel before mechanical bottom). This motor drives a 3″ diameter 4-layer flat aluminum coil wound on a thick aluminum former to incredible levels of excursion. This is the same coil design utilized in the NS v.3 and Z v.5 series in the past. It is a proven coil with monstrous power handling potential. The combination of coil and updated motor for the X v.3 series brings its performance in terms of motor force to about 85% of the level of the previous generation Z v.5 series! So this makes the X v.3 an incredible value.

The X v.3 series was designed from the ground-up to become the new standard in the low-frequency / small ported box subwoofer category in this price range. They will work in the same small enclosures that you are used to using for Sundown Audio subwoofers, although, the will tolerate enclosures up to about 50% larger than those if you desire even more low-end extension.

The X v.3 series is really a different kind of woofer due to its incredibly linear suspension. They are designed for the LOWEST level of bass extension possible in a small enclosure while maintaining extremely low levels of distortion.

The Sundown Audio SALT amplifiers represent the pinnacle of Korean Class-D amplifier technology. They stand on the shoulders of the previous three generations of Sundown high-end Korean amplifiers spanning 15-years (the SAZ v.1, SAZ, v.2, and SCV series) to reach even greater heights of performance. Our customers, for many years, have asked us to produce amplifiers that produce optimum power at realistic operating voltages in the 12s rather than 14+ volts. The SALT – Sundown Audio Low-Voltage Technology – series is our answer!

Whether you are a world-class SPL competitor, a dedicated enthusiast, or even a fan of Sound Quality the SALT series will be right at home in your system. Each and every model has been created with painstaking attention to detail to ensure that they bring a smile to your face each time the music starts playing and, further, to last for many years to come.

Cosmetically they are a huge departure from our original styling as an outward indicator of the enhanced levels of performance. The heat-sink is the heaviest we have ever produced, with the most surface area, and is finished with a striking titanium color. These amplifier looks as good as they sound and as soon as you hold one in your hands the build-quality is obvious. The icing on the cake lies in the revised remote control which features temperature, voltage, and clipping indicators to easily monitor the vitals of your valuable audio system.
