The PSD 215 (1 x 15") and PSD 218 (1 x 18") are high-performance powered subwoofers designed to simplify creating active 2-way systems. They use an integrated 2 x 1.000W RMSdigital power amplifier with internal 24-bit 1-in-3 DSP controller to optimize the sound quality and protect the subwoofer and full range system used with it.

The PSE 215 and PSE 218 are the non powered versions of the PSD subs, share the same dimensions, transducer configurations, and the acoustic characteristics allowing them to be used with PSD 215 and PSD 218 without additional amplifiers when greater SPL is required.
The PSE 215 and 218 may also be used as a subwoofer in any other active system combination.
