Delta-X218B is a dual-chamber dual 18-inch passive subwoofer designed to deliver the most powerful low-frequency performance.
Crafted from 18 mm birch plywood and finished in our durable Tough-Tone paint, the cabinet is road-ready and built for the heaviest use.
Inside, two custom Wharfedale Pro 18-inch LF drivers generate immense, chest-thumping bass that stays tight and controlled, even at extreme levels.
Rated at 1,600 W continuous (up to 6,400 W peak) in Parallel mode and capable of 138 dB SPL, the Delta-X218B has the headroom to underpin the largest systems with authority.
On the rear panel, a switch allows you to select Parallel mode, where both drivers share a single amplifier channel, or Discrete mode, where each driver can be powered separately for maximum system control. Heavy-duty side handles and a 35 mm pole socket complete a design that combines massive output with practical deployment for professional sound reinforcement.
