Sundown Audio

The Sundown U Series is our premier “standard suspension” woofer series. The all-new U v.2 improves on the already incredible performance of its predecessor.

We start with a double-stacked / 9.44” wide Y35 grade ferrite magnet system (3/4” wider than the v.1) coupled to a one-piece, bumped T-Yoke and a 0.6” thick top-plate. Just as with our other high-end subwoofers we also add a very thick (5mm thickness) aluminum shorting ring inside the magnets to reduce static inductance and level out inductance over stroke. The v.2 adds a pole-cap aluminum shorting ring which doubles as a heat-sink and airflow guide. The U v.2 series motor also features a 0.6” long pole-extension to keep the coil under control at high levels of excursion.

The Sundown Audio VEX series is our top-of-the-line high efficiency mid-range series. The first entry, the VEX-10, was designed to make a splash featuring a 500-watts RMS power rating thanks to its enormous 3” coil (with a full 20mm winding length) and highly efficient airflow system consisting of twelve gaps vents and a chamfered, large-diameter pole vent. The long coil also affords the VEX-10 a full 9mm of linear x-max one-way so it can play lower than many other high-efficiency drivers without distortion. The inductance is kept in check by a dual shorting-ring system (magnet ID & pole cap) which drops the LE spec to less than 25% of the RE value. This allows the high-frequency extension to reach all the way up to 4,000 Hz where it then falls of naturally and smoothly on its own thanks to the extremely strong and non-resonant carbon-fiber cone & dust-cap assembly.

The Sundown Audio VEX series is our top-of-the-line high efficiency mid-range series. The VEX-8 was designed to handle an enormous 300-watts RMS thanks to its generous 2.5” coil (with a full 20mm winding length) and highly efficient airflow system consisting of twelve gaps vents and a chamfered, large-diameter pole vent. The long coil also affords the VEX-8 a full 9mm of linear x-max one-way so it can play lower than many other high-efficiency drivers without distortion.

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.
