YORKVILLE UCS1 15-inch Horn Loaded

YORKVILLE  UCS1 15-inch Horn Loaded
The UCS1 was designed for use with the Unity™ U15 or U215 loudspeaker systems and is the ideal passive subwoofer to match their acoustic parameters. But as with all Yorkville subs, the UCS1 can be employed with any full-range enclosure, especially those with high output.

This 1200-watt, 8-ohm "earth mover" takes full advantage of its horn-loaded design to deliver fierce bottom end from a surprisingly compact, single 15-inch-loaded passive subwoofer. The level of performance UCS1 delivers from a box this manageable in size is the direct result of outstanding loudspeaker cabinet design. Optimized horn flare geometry, careful attention to the front and rear internal chamber dimensions, as well as the use of a high performance long excursion 15-inch driver, gives the UCS1 surprisingly high output volume and deep, extended bass response. All this in an enclosure occupying only a total volume of just over 11 cubic feet.
