What is the role of an 18-inch subwoofer in a PA system?

The SR18S delivers powerful low-frequency bass reinforcement, supporting full-range speakers to extend sound into deep bass frequencies essential for music, dance events, and large venue fill.

How much power does the 1600W built-in amplification provide?

The 1600W Class-D amplifier drives the 15-inch woofer with ample headroom for clean, dynamic bass without distortion even at high SPLs.

What venues benefit from an 18-inch subwoofer?

Nightclubs, concert halls, outdoor festivals, large corporate events, houses of worship, and venues with 500+ capacity use 18-inch subs for full-spectrum bass impact.

What does the bandpass enclosure design contribute?

The bandpass cabinet tunes the subwoofer for efficient bass output over a specific frequency range, maximizing output and minimizing distortion compared to traditional designs.

High-pass modes filter out rumble and subsonic frequencies below the subwoofer's optimal operating range, protecting the driver and ensuring cleaner, tighter bass.
