The NEXT-proaudio PFA18sHP is an active front-loaded reflex subwoofer engineered for high-level, extended low-frequency performance in touring and fixed installations. Powered internally by an integrated Class D amplifier delivering up to 5920W peak power, it drives a custom European 18-inch long-excursion woofer with a 4-inch voice coil to produce up to 142 dB peak SPL.

Advanced onboard 24-bit/48kHz DSP offers comprehensive acoustic control with six factory presets and two user-defined slots editable in real time using the included Soundware software. A top-mounted 35mm (1.4 in) pole socket enables seamless integration with satellite speakers for versatile ground-stacked PA configurations.
