Wharfedale Pro - DELTA-X15B 15" Subwoofer With Bi-amp Functionality
Delta-X15B is a compact 15-inch passive subwoofer designed to deliver powerful low-end reinforcement in portable and installed sound systems.
Constructed from 18 mm birch plywood and finished in our rugged Tough-Tone paint, it’s engineered to withstand the demands of touring while maintaining a professional appearance.
Optimised to complement the Delta-X full-range loudspeakers, the rear panel allows straightforward integration into both passive and bi-amped system setups.
Handling 700 W continuous power (up to 2,800 W peak) and reaching a maximum SPL of 132 dB, the Delta-X15B adds depth and punch without overwhelming smaller venues or mobile rigs.
A Wharfedale Pro custom LF driver delivers tight, responsive bass, while the carefully tuned cabinet design ensures clarity and control at high volumes.
With integrated side handles and a 35 mm pole socket, the Delta-X15B is easy to transport, position, and deploy—bringing solid low-frequency support to the Delta-X series.
