Wharfedale Pro DELTA-X18B4 Passive Subwoofer

The Wharfedale Pro DELTA-X18B4 Passive Subwoofer is a high-powered 18-inch passive subwoofer built to deliver deep, authoritative low-end for live sound and fixed installations.
Its enclosure is crafted from 18 mm birch plywood and finished in our durable Tough-Tone paint, ensuring strength and resilience for touring and repeated use.

Designed to extend the performance of the Delta-X full-range cabinets, the rear panel offers connectivity that allows easy integration into either passive or bi-amped system configurations.

With 800 W continuous power handling (up to 3,200 W peak) and a maximum SPL of 134 dB, the Delta-X18B adds serious depth and impact to any setup. A Wharfedale Pro custom LF driver, mounted in the optimised cabinet, delivers tight, punchy bass that stays controlled even at high output levels.

Equipped with a 35 mm pole socket and robust side handles, the Delta-X18B is practical to deploy while bringing heavyweight low-frequency performance to the Delta-X family.
