It pairs a 12\" high-output woofer with a 1.8\" neodymium compression driver and handles 350 W continuous (AES) at 8 Ω. A tight 40° x 40° coverage pattern and IP54 rating suit stadiums, sports facilities, campuses, theme parks and event venues where sound must reach a long distance.\u003c\/p\u003e\u003ch2\u003eHow does the AUDAC HS212MK2 12\" horn loudspeaker work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/images.pvs.global\/audac\/products\/HS212.webp?width=1200\" alt=\"AUDAC HS212MK2 12 inch full-range horn loudspeaker\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eThe HS212MK2 is a passive, low-impedance (8 Ω) horn system. A built-in passive crossover at 1.5 kHz splits the signal between the 12\" woofer and the 1.8\" compression driver, whose horn is built as one piece with the enclosure. The result is an 80 Hz – 18 kHz response (±3 dB), 95 dB sensitivity and 125 dB maximum SPL, giving clear, intelligible speech at low distortion along with full-range music. The 40° x 40° coverage concentrates energy for long throw, so fewer cabinets cover a large stand or field. The enclosure is multi-layer glass composite with a textured EPDM coating, and acoustic foam behind the powder-coated aluminum grill keeps rain out. Two heavy-duty Speakon connectors allow linkthrough to other cabinets on the same amplifier channel.
