Sundown Audio U-10 V2 D2 10" 1750W RMS Dual 2-Ohm U-Series Subwoofer SKU #: 04088

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 voice coil is a 2.36” long / 3” diameter 4-layer aluminum winding / aluminum former unit – which is the same coil design from the U v.1 – but the new version is built with a stronger aluminum former. The coil temperature is kept in check via a high-velocit
