Perfectly tuned for use with the DELTA AX15B and DELTA AX18B active subwoofers, the DELTA AXF12 unlocks the full potential of the DELTA platform for professional PA applications demanding both proven durability and cutting-edge sonic performance.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eEnhanced Amplification \u0026amp; Backward Compatibility\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe optimised Class-D amplifier module delivers 800W continuous and 1600W peak power — providing increased headroom and tighter, more dynamic performance compared to its predecessor — whilst maintaining complete backward compatibility with previous DELTA Active models. AXF amplifier modules are fully interchangeable with earlier DELTA Active cabinets and can be retro-fitted by service engineers with ease, protecting existing investments and simplifying fleet management for touring and rental companies. A high-efficiency SMPS power supply with universal mains input (100–120V \/ 220–240V, 50\/60Hz) ensures consistent performance across worldwide operating voltages.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003ePremium 2-Way Driver Configuration\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe DELTA AXF12 is built around a 12\" custom Wharfedale Pro LF driver with a 3\" voice coil and 8 Ohm impedance — chosen for high power handling, controlled excursion and consistent performance under sustained professional use. The high-frequency section features a compression driver with a 2\" titanium diaphragm and 1.4\" exit, delivering 50W HF power handling with the rigidity and high-temperature resistance that titanium diaphragms are valued for in professional touring applications. An elliptical waveguide provides a 90° horizontal by 45° vertical coverage pattern for precise, controlled sound distribution across the audience area, with a 2.1kHz crossover frequency providing clean driver integration across the full frequency range.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eVersatile Connectivity \u0026amp; Deployment\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe DELTA AXF12 accommodates a wide range of source connections via a combination XLR\/¼\" jack combo input alongside two RCA inputs, with a balanced input impedance of 20kΩ and a maximum input level of +22dBu. Mic (-40dBu) and line (0dBu) input sensitivity settings provide flexible gain structure for different source types. A switchable loop\/mix balanced XLR line output provides flexible signal routing to additional speakers or subwoofers. The cabinet features six M10 rigging points for safe and secure flying, a dual-angle 35mm pole mount socket (0° and 10°) for stand-mounted deployment, and recessed handles for practical transportation — making the DELTA AXF12 equally at home in flown, stand-mounted and ground-stacked configurations.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eTouring-Grade Construction\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe DELTA AXF12 enclosure is constructed from birch plywood with a black Tough-Tone finish for long-term resistance to the knocks and abrasions of professional touring and installation use. The steel black powder-coated grille provides robust driver protection, and two recessed handles provide practical carry points for transportation and rigging.\u003c\/p\u003e\n\u003ch3 class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eWharfedale Pro DELTA AXF12 Key Features: \u003c\/h3\u003e\n\u003cul\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eFIR Filter DSP Platform:\u003c\/strong\u003e Derived from the flagship WLA-1A system — precise magnitude and phase control, improved frequency response and a more defined, consistent sound.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e12\" Custom Wharfedale Pro LF Driver:\u003c\/strong\u003e 3\" voice coil for high power handling and consistent performance under sustained professional use.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eTitanium Compression Driver:\u003c\/strong\u003e 2\" titanium diaphragm, 1.4\" exit for high rigidity, strength and temperature resistance in professional touring applications.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e800W Continuous \/ 1600W Peak Class-D Amplification:\u003c\/strong\u003e Increased headroom and tighter, more dynamic performance over the previous DELTA Active generation.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e130.5dB Maximum SPL:\u003c\/strong\u003e High output for demanding professional live sound environments.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e55Hz–20kHz Frequency Range (-10dB):\u003c\/strong\u003e Wide, full-range response for professional PA applications.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e90° x 45° Coverage Pattern:\u003c\/strong\u003e Precise, controlled sound distribution via elliptical waveguide.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e2.1kHz FIR Crossover:\u003c\/strong\u003e Clean, phase-coherent driver integration across the full frequency range.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eBackward Compatible:\u003c\/strong\u003e AXF amplifier modules fully interchangeable with previous DELTA Active models for easy retro-fitting.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePerfectly Tuned for DELTA AX15B \u0026amp; AX18B Subwoofers:\u003c\/strong\u003e Optimised system integration with compatible DELTA active subwoofers.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eXLR\/Jack Combo \u0026amp; RCA Inputs:\u003c\/strong\u003e Flexible source connectivity with mic and line sensitivity settings.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eSwitchable Loop\/Mix XLR Output:\u003c\/strong\u003e Flexible signal routing to additional speakers and subwoofers.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e6 x M10 Rigging Points:\u003c\/strong\u003e Safe and secure flying for permanent installation and touring.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eDual-Angle 35mm Pole Mount (0° \u0026amp; 10°):\u003c\/strong\u003e Flexible stand-mounted deployment options.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eBirch Plywood Enclosure with Tough-Tone Finish:\u003c\/strong\u003e Touring-grade durability for professional live sound and installation.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eHigh-Efficiency SMPS Power Supply:\u003c\/strong\u003e Universal mains input (100–240V) for worldwide compatibility.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Wharfedale Pro","offers":[{"title":"Default Title","offer_id":57177491702133,"sku":"DELTA-AXF12","price":619.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2083\/7259\/files\/DELATA-AXF12.png?v=1778668887","url":"https:\/\/www.audiovolt.co.uk\/products\/wharfedale-pro-delta-axf12-800w-active-pa-speaker","provider":"Audio Volt ","version":"1.0","type":"link"}
