The all-new U v.2 improves on the already incredible performance of its predecessor.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eWe 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.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe 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-velocity solid pole \/ machined pole channels arrangement and a series of 16 direct air-gap vents in the back plate. The U v.2 series also features custom tooled cast aluminum vent rings in between the frame and top plate to effectively exchange air at a high velocity over the voice coil beneath the spider landing.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eThe U v.2 series features an all-new, custom tooled, cast aluminum frame designed specifically for this line. The cosmetics are very similar to the original v.1 frames but every size frame is substantially thicker and even features stiffening \/ heat dissipation ribs around the bottom part of the frame. The new frame design allows for significantly taller cones and wider spiders on the 10s and 12s compared to the v.1 which greatly enhance mechanical clearances. Moving on to the 15 the spider is also wider than the originals. The 18 uses the same spider and cone height as the originals but the frame is, of course, much stronger.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eGiven the stronger motor (15% more powerful), stronger coil construction, superior motor air-flow characteristics, and enhanced mechanical capacity we boosted the power rating to 2000-watts RMS from the 1500-watt rating of the previous version.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eIf you are looking for a woofer that sounds similar to the SA series but handles significantly more power… the U v.2 series is exactly what you need. It has been designed to live up to the reputation earned by our U v.1 series both in terms of every-day music enjoyment and SPL competition.\u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"
