Big bass for installation or mobile.

The 1400-watt dual 12-inch active PSA1S bass reflex subwoofer is the ideal companion sub for the PSA1 full range loudspeaker system. Solid 15mm birch plywood cabinet construction and an integrated all-metal pole-mount adaptor make the PSA1S the perfect platform for stacking PSA1 cabinets in a scalable array system. Compact design, heavy-duty wheels and handles ensure the PSA1S can easily be handled by a single operator for economical system set-up.

Efficient Class-D power amplifier design provides unmatched long-term reliability in the field. Cable of direct connection to any audio source (including speaker level input) the PSA1S can be easily integrated in to virtually any PA application, making it one of the most versatile active subwoofer solutions Yorkville Sound currently offers.

Heavy Duty Precision Stand Adaptor
The PSA1S Subwoofer is one of the first products to use Yorkville Sound's new Heavy Duty Precision Stand Adaptor. In order to minimize top cabinet sway and provide an improved standmount platform for multiple PSA1 cabinets, the PSA1S subwoofer standmount adaptor uses an extremely thick walled cast aluminum stand receiver with a wider mounting plate than has been used on Yorkville subwoofers in the past.

Precision machining after casting allows the highest tolerances possible, this new improved stand adaptor provides a more stable, highly secure pole mount system for mobile Paraline systems when used in combination with the Yorkville SW-TUBEHD Heavy Duty all steel subwoofer tube.
