It is well suited to medium-sized venues, theatres, clubs, bars, hotels, houses of worship, conference spaces, event production and commercial audio systems that need strong bass impact with reliable system performance.\u003cspan aria-hidden=\"true\" class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"2037\" data-end=\"2381\"\u003eBuilt around two long-excursion 15” drivers with 4” voice coils, the SX215 delivers substantial low frequency output with excellent headroom. The drivers use water-resistant cones and triple roll surrounds, while eight reflex ports with a large frontal area help improve low frequency efficiency and reduce air noise at higher operating levels.\u003c\/p\u003e\n\u003cp data-start=\"2383\" data-end=\"2862\"\u003eWith 1600W AES power handling and 6400W peak capability, the SX215 is designed for demanding systems where smaller subwoofers may not provide enough output or extension. Its 4Ω passive design requires suitable amplification and dedicated DSP processing, with the crossover frequency typically set around 100Hz. Correct amplifier matching, crossover setup and limiter configuration are important to achieve reliable performance and balanced integration with the main loudspeakers.\u003c\/p\u003e\n\u003cp data-start=\"2864\" data-end=\"3237\"\u003eThe SX215 can be used as a single subwoofer, stacked with additional units using the locating skids and mating channels, or suspended using the integrated threaded inserts and suitable rated hardware. It also includes an M20 top-mounted pole mount plate, allowing compatible full-range loudspeakers to be positioned above the subwoofer in portable or compact venue systems.\u003c\/p\u003e\n\u003cp data-start=\"3239\" data-end=\"3583\"\u003eFor more controlled bass deployment, the SX215 can be configured for cardioid operation when used in forward and rear-facing pairs, with each enclosure powered individually and processed using the correct DSP presets. This helps reduce rearward low frequency energy, making it useful in venues where bass control behind the system is important.\u003c\/p\u003e\n\u003cp data-start=\"3585\" data-end=\"4059\" data-is-last-node=\"\" data-is-only-node=\"\"\u003eThe cabinet is constructed from plywood and finished in hardwearing black textured paint. Four ergonomic handles assist with handling and positioning, while the coated steel grille with acoustically transparent fabric backing protects the drivers during transport, installation and operation. The Martin Audio SX215 is a strong choice for professional systems requiring powerful dual 15” subwoofer performance, flexible deployment and dependable low frequency reinforcement.\u003c\/p\u003e","brand":"Martin Audio","offers":[{"title":"Black","offer_id":56735064588674,"sku":"SX215","price":2345.0,"currency_code":"GBP","in_stock":true},{"title":"White","offer_id":56735064621442,"sku":"SX215-W","price":2345.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/5767\/2578\/files\/SX215.png?v=1782476774","url":"https:\/\/www.theavbarn.co.uk\/products\/martin-audio-sx215","provider":"The AV Barn","version":"1.0","type":"link"}
