DELTA-AXF15 is a 15″ bi-amplified active loudspeaker from our upgraded DELTA-AXF Series — delivering increased power, improved clarity, and professional FIR-processed performance in a robust plywood enclosure. Driven by an enhanced amplifier module providing 800 W continuous (1600 W peak) power, DELTA-AXF15 offers impressive output with a max SPL of 131.5 dB @ 1 m. Its custom-designed 15″ LF driver with a 3″ voice coil delivers tight, punchy low-end, while a 2″ HF compression driver ensures clear, articulate highs with a controlled 90° x 45° dispersion for consistent coverage. Thanks to newly integrated internal FIR DSP, the system benefits from precise magnitude and phase alignment, smoother crossover performance and enhanced overall definition — technology derived from our WLA-1A System.
