Delta-X12 is a versatile 12-inch 2-way passive loudspeaker that balances power and portability, making it ideal for live venues, installs, or mobile rigs.
Constructed from 15 mm birch plywood and finished in durable Tough-Tone paint, it’s built to handle the knocks of life on the road while maintaining a professional look.
Like the rest of the Delta-X family, the rear panel gives you the choice of running in full-range passive mode or switching to a bi-amped setup for greater control over low and high frequencies with separate amplifiers.
Delivering 400 W continuous (up to 1,600 W peak) and capable of 129 dB max SPL, the Delta-X12 packs serious output into a manageable enclosure. A Wharfedale Pro custom LF driver ensures tight, punchy bass, while the titanium-diaphragm compression driver provides clear, defined highs. With a dual-angle pole socket and ergonomic side handles, it’s practical to position, carry, and integrate into any system.
