This bundle pairs a Sundown Audio U-Series v.1 12-inch subwoofer with a Sundown Audio UV1 single ported MDF enclosure. The subwoofer is not pre-installed. You mount it in the enclosure yourself. The enclosure arrives bare and sanded, ready for you to finish as you like.
The U-Series v.1 has a standard-suspension design and is rated at 1,500W RMS. It uses a double-stacked 8.66-inch Y35 ferrite motor on a one-piece bumped T-yoke, with a 0.6-inch top plate, a 5mm aluminum shorting ring and a 0.6-inch pole extension. The 3-inch, 4-layer aluminum voice coil is the same unit used in the X v.2 series. Cooling comes from a high-velocity pole vent, ten back-plate air-gap vents and cast-aluminum vented frame spacer rings. It is optimized for small ported or bandpass enclosures.
The enclosure is built to order by Basshead Supply by hand in the USA. Its panels are dense, void-free triple refined MDF, glued with Titebond III and internally braced. The assembly leaves no visible screw holes. It comes pre-wired with a recessed satin-nickel binding post and 10-gauge OFC wire.
