The UCS1P was designed for use with the any of the Unity™ passive or active loudspeaker systems – U15, U15P or U215 – and is the ideal active subwoofer to match their acoustic parameters. But as with all Yorkville subs, the UCS1P can be employed with any full-range enclosure, especially those with high output, in many cases without even the need of a crossover.
