Exceptional power reserves combined with minimal distortion make the hd Infra218 a modern yet flexible tool for touring applications and large-scale installations requiring extreme bass, high SPL, and excellent dispersion control.\u003c\/p\u003e\n\u003cp\u003eThe optimally tuned, horn-loaded, bass-reflex hybrid cabinet houses two special 18\" long-excursion drivers with 5\" voice coils. A large, flow-optimized central reflex port ensures minimal turbulence and distortion. The frequency response from 28 Hz to 120 Hz makes the Infra218 perfectly suited to extend the bass for all Harmonic Design speakers. Thanks to its long throw, high efficiency, and directivity, the hd Infra218 can be optimally integrated into Line Array applications.\u003c\/p\u003e\n\u003cp\u003eCardioid emission is generated passively with two or three stacked hd Infra218 units. An M20 threaded insert on the top and side of the cabinet allows for the insertion of a pole to secure satellite speakers or a spacer bar. High-strength PVC protection feet on two sides and corresponding recesses on the top of the enclosure ensure secure stacking.\u003c\/p\u003e\n\u003cp\u003espeakON NL4 connectors, mounted on the rear of the recessed connection panel, are used to connect and route the input signal. A speakON socket in the protective front grille allows for cardioid configurations without special interchangeable cables.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMain Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003eHigh-performance hybrid subwoofer with 2 x 18” woofers (3600 W\u003csub\u003eRMS\u003c\/sub\u003e \/ 14,400 W peak)\u003c\/li\u003e\n\n\u003cli\u003eFrequency response: 28 – 120 Hz\u003c\/li\u003e\n\n\u003cli\u003e149 dB SPL max\u003c\/li\u003e\n\n\u003cli\u003ePassive directivity for stacks of 3 units\u003c\/li\u003e\n\n\u003cli\u003e2 x M20 threads\u003c\/li\u003e\n\n\u003cli\u003eWeight: 89 kg\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eSPECIFICATIONS\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\n\u003cp\u003e\u003cstrong\u003eTechnical characteristics\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003ePrinciple: bass-reflex system horn-loaded\u003c\/li\u003e\n\n\u003cli\u003eTransducers: 2 x 18″ long excursion woofer with a 5″ voice coil, vented at the pole piece and spider\u003c\/li\u003e\n\n\u003cli\u003eCrossover: active up to max. 120 Hz\u003c\/li\u003e\n\n\u003cli\u003ePower handling: 3600 W\u003csub\u003eRMS\u003c\/sub\u003e \/ 14,400 W peak\u003c\/li\u003e\n\n\u003cli\u003eFrequency response: 28 – 120 Hz\u003c\/li\u003e\n\n\u003cli\u003eSensitivity: 102 dB\/W\/m\u003c\/li\u003e\n\n\u003cli\u003eSPL max: 149 dB (half space)\u003c\/li\u003e\n\n\u003cli\u003eNominal impedance: 4 ohm\u003c\/li\u003e\n\n\u003cli\u003eEnclosure: robust multiplex housing, polyurethane coating black, recessed connection panel with 2 x NL4 rear, turning socket NL4 front, 2 x M20 threads, 6 x transport handles, steel grille with acoustic foam inside\u003c\/li\u003e\n\n\u003cli\u003eConnections: 2 x speakON NL4, 1 x speakON NL4 turning socket\u003c\/li\u003e\n\n\u003cli\u003eOptions: transport protection cover, hd SlientWheels Set, weather protection and RAL color customization\u003c\/li\u003e\n\n\u003cli\u003eDimensions: 119 x 53.6 x 67 cm\u003c\/li\u003e\n\n\u003cli\u003eWeight: 89 kg\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\n\u003c\/ul\u003e","brand":"Harmonic Design","offers":[{"title":"Default Title","offer_id":54311865057613,"sku":"60030","price":5505.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/0643\/6173\/files\/36761_60030_big.jpg?v=1784203844","url":"https:\/\/musicdelivery.net\/en\/products\/harmonic-design-infra218","provider":"Music Delivery","version":"1.0","type":"link"}
