{"product_id":"u15v2-15-inch-dual-4-ohm-subwoofer","title":"U15v2 15-Inch Dual 4-Ohm Subwoofer","description":"The Sundown U15v2 is a premier \"standard suspension\" woofer series, designed as a direct replacement for the popular Z v.3 line, offering comparable performance at a reduced cost. This 15-inch dual 4-ohm subwoofer is engineered for demanding audio applications, including SPL competition and everyday music enjoyment.\n\nConstruction highlights include a robust double-stacked 8.66” Y35 grade ferrite magnet system, paired with a bumped T-Yoke and a 0.6” thick top-plate. A 5mm thick aluminum shorting ring is integrated within the magnets to minimize static inductance and stabilize inductance across the stroke. The voice coil is a 3-inch diameter, 4-layer aluminum winding on an aluminum former, measuring 2.36” long, which contributes to its 1500-watt RMS power rating. Cooling is managed through a smoothed, high-velocity pole vent, ten direct air-gap vents, and innovative cast aluminum vent rings that facilitate high-velocity air exchange over the voice coil.\n\nThe U Series features a newly tooled cast aluminum frame, enabling taller cones for enhanced coil stability and increased mechanical excursion. Matching cast-aluminum surround clamps ensure durability under high demand. The cone bodies and surrounds are custom-tooled for strength and greater excursion capability than previous series, with an indentation for wide-flange, ultra-strong dust caps.\n\nKey features include a black aluminum 3” voice coil former for superior heat dissipation, a high-temperature round-wire CCAW voice coil, double stitched surround, heavy-duty cast basket, and spring-loaded terminals accepting up to 8-gauge wire. It is optimized for small ported or bandpass enclosures, with recommended specifications for a 3.0 cu ft ported enclosure tuned to 35Hz.","brand":"Sundown","offers":[{"title":"Default Title","offer_id":52866414575928,"sku":"SNDN-U15D4v2","price":669.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687698896.webp?v=1787907474","url":"https:\/\/store.motormia.co\/products\/u15v2-15-inch-dual-4-ohm-subwoofer","provider":"MOTORMIA","version":"1.0","type":"link"}
