The Power Dynamics PDY218SA stands out as a high-quality 18-inch active PA subwoofer, boasting a 1000W class D amp. This active sub can achieve a remarkable max SPL of 128dB, rendering it ideal for large applications like live band performances, DJ events, and club nights. Delivering powerful sub-bass frequencies at high volumes, the PDY218SA is an excellent choice for a wide range of settings.

On the back panel of this active sub, you’ll find two pairs of balanced XLR outputs. One set emits a full-range signal, ideal for linking to another subwoofer. On the other hand, the high-pass output sends only mid and high-range frequencies out. This is advantageous when connecting full-range satellite speakers to the sub, as it ensures the active sub manages the bass, while the primary speakers focus on the treble, optimising volume and overall sound quality.

An adjustable crossover function enables users to adjust the frequency output depending on the sound source, venue, and the accompanying speakers in their setup. In addition, a phase switch is present, introducing a minor delay to the subwoofer’s sound to harmonise seamlessly with your overall PA system.

This active PA subwoofer features RCA, 6.3mm Jack, and balanced XLR inputs at the back. The XLR inputs, designed for maximum signal fidelity, are ideal for connecting mixing desks. At the same time, the RCA and 6.3mm Jack inputs provide a straightforward connection option for devices like laptops or DJ controllers when necessary.

Robustness defines the PDY218SA active sub, courtesy of its sturdy plywood shell complemented by a rugged exterior coating. Incorporated side handles ensure convenient movement of the subwoofer, and the 35mm tophat hole on the top of the housing allows easy mounting of satellite speakers using a suitable speaker pole.
