The result is significantly higher output than a conventional reflex-loaded cabinet of equivalent size — delivering 148 dB peak SPL from a ground-stacking touring enclosure optimised for festival, theatre, and large-venue production.\u003c\/p\u003e  \u003cp\u003eDual neodymium long-excursion 18-inch drivers with 4.5-inch voice coils and water-resistant triple roll surrounds are housed in a multi-laminate plywood enclosure coated in hard-wearing textured black polyurea. A rigid perforated steel grille provides driver protection. The cabinet supports both forward and rear-facing operation, enabling cardioid ground-stack configurations with paired enclosures. Can be driven by a single channel of a Martin Audio iK42 amplifier, or a bridged pair for maximum output.\u003c\/p\u003e  \u003cul\u003e \u003cli\u003eDual 18\" (460 mm) neodymium long-excursion drivers — 4.5\" (115 mm) voice coil\u003c\/li\u003e \u003cli\u003ePower handling: 3,400 W AES \/ 13,600 W peak; impedance 4 Ω nominal\u003c\/li\u003e \u003cli\u003eFrequency response: 32 Hz – 150 Hz ±3 dB (–10 dB @ 27 Hz)\u003c\/li\u003e \u003cli\u003eMaximum SPL: 148 dB peak (154 dB peak with crest factor 4) @ 1 m\u003c\/li\u003e \u003cli\u003eDimensions (W×H×D with skids): 1,112 × 609 × 1,023 mm; weight 124 kg\u003c\/li\u003e \u003c\/ul\u003e  \u003cp\u003eThe ideal sub-bass choice for large-scale touring productions, festival main stages, theatre \u0026amp; broadcast events, and any application demanding the maximum output per footprint.\u003c\/p\u003e","brand":"Martin Audio","offers":[{"title":"Default Title","offer_id":56109833978159,"sku":"SXH218","price":16543.14,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0960\/2210\/2319\/files\/SXH218_396044dc-8c33-4b1b-8485-70c200511191.jpg?v=1778614159","url":"https:\/\/audioconnect.co.nz\/products\/sxh218","provider":"Audio Connect","version":"1.0","type":"link"}
