Wharfedale DeltaX218B Bass Speaker Dual 18-Inch High-Output Passive Subwoofer

The Wharfedale DeltaX218B Bass Speaker is a high-output dual 18-inch passive subwoofer designed for demanding live sound reinforcement applications. It is built to deliver deep, powerful, and controlled low-frequency performance for large concerts, outdoor festivals, clubs, and touring PA systems where strong bass impact is essential.

At the core of the Wharfedale DeltaX218B Bass Speaker are two precision-engineered 18-inch low-frequency drivers housed in a tuned bass reflex enclosure. This dual-driver configuration significantly increases sound pressure level (SPL) output while extending low-frequency response, producing deep, punchy bass that remains tight and controlled even at high volumes.

The Wharfedale DeltaX218B Bass Speaker is designed for use with high-power external amplifiers and DSP-based active crossovers, allowing sound engineers to optimize system performance based on venue size and acoustic conditions. Its rugged cabinet construction ensures durability under continuous touring use, making it suitable for both portable PA systems and fixed installation environments.
