DELTA-AX12

12" active loudspeaker - with advanced internal QuBit DSP

The Delta-AX12 is a no-nonsense powerhouse for those needing clear, impactful sound in venues, PA setups, or installations. It’s built tough using premium birch-plywood and coated in a textured Tough-Tone finish to stay road-ready through years of touring and use. Its bi-amplified design with internal DSP ensures balanced, punchy output with no overload, even at high volumes, while a wide 90° × 45° dispersion means your audience gets even coverage, whether it’s a hall or a café. Handles, multiple rigging points and dual-angle pole sockets give real flexibility during setup—stack, stand or suspend, as needed. Add intuitive tone-shaping and protection features, and you’ve got a loudspeaker that sounds great, travels well, and simply gets the job done beautifully.
