PX 18SUB

PX18SUB

The PX18SUB is an 18-inch active subwoofer from the PX Series, built to deliver high-output, low-frequency reinforcement for demanding sound systems. As a heavy-duty sub-bass engine, it is ideal for high-impact applications including concert touring, outdoor festivals, nightclubs, and large venue installations. Designed to anchor full-range systems with profound low-end energy, the PX18SUB provides acoustic consultants and audio engineers with maximum sub-bass presence.

Driven by an active power plant, the PX18SUB boasts 800 Watts AES of continuous power and a massive 1600 Watts Peak capacity. Capable of generating a maximum SPL of 105 dB Peak, this active subwoofer offers exceptional dynamic headroom. It drives massive volume levels into the room while maintaining absolute bass clarity and structural enclosure stability under heavy excursion.

At the heart of the PX18SUB is a premium 18-inch (450 mm) low-frequency driver equipped with a massive 4-inch voice coil. This heavy-duty voice coil configuration provides superior motor control and thermal dissipation under extreme low-end loading, moving vast volumes of air to deliver uniform, omnidirectional low-frequency output across the entire performance space.

With a tuned frequency response running from 35 Hz up to 120 Hz (±3dB), the PX18SUB generates deep, physical bass tones alongside punchy upper-sub frequencies. The dedicated internal filtering ensures pure acoustic output without unwanted midrange bleed, providing a clean, phase-coherent foundation that pairs effortlessly with active two-way loudspeakers.

Built inside a heavily braced, road-ready cabinet, the unit is constructed to withstand severe touring environments. It features complete system signal connectivity with dual XLR inputs, dual XLR direct outputs, two Nutrik NL-4 SpeakON connectors, and standard AC 220V (50-60Hz) power input. Rated at a 4 Ohm nominal impedance, the PX18SUB is an indispensable, ultra-reliable foundation for professional live sound.
