Delta-X15 is a powerful 15-inch 2-way passive loudspeaker designed for larger venues, touring rigs, and demanding mobile setups.
Its cabinet is built from 15 mm birch plywood and finished in our Tough-Tone paint, giving durability that stands up to the rigours of transport and heavy use.
On the rear panel, a mode switch allows operation in full-range passive mode or in a bi-amped configuration, letting you drive low and high frequencies independently for maximum control.
With 500 W continuous power handling (up to 2,000 W peak) and a maximum SPL of 131 dB, the Delta-X15 delivers serious volume and authority. A Wharfedale Pro custom 15-inch LF driver provides deep, powerful bass, while the titanium-diaphragm compression driver ensures articulate, defined highs.
Fitted with a dual-angle pole socket and side handles, the Delta-X15 combines muscle with practicality, making it a versatile choice for professional sound reinforcement.
