{"product_id":"qsc-ls218","title":"QSC LS218 Dual 18\" Direct-Radiating Active Subwoofer With Dante","description":"\u003cp\u003eThe QSC LS218 is engineered for production engineers and AV integrators who demand scalable, networked low-frequency reinforcement without sacrificing deployment flexibility. Whether rigged alongside LA108 or LA112 line array systems for touring productions, or configured into fixed installations with Dante-networked signal routing, the LS218 brings intelligent subwoofer management to complex multi-zone and multi-array environments. Its dual direct-radiating transducer configuration and Class D amplification deliver the headroom required for large-venue live events, houses of worship, and permanent installs where consistent coverage across the entire audience plane is non-negotiable.\u003c\/p\u003e\u003cp\u003eThe LS218 supports both omni-directional and cardioid radiation modes, giving system designers precise control over low-frequency energy distribution — reducing rear and side bleed in constrained venues when two or more units are deployed in cardioid configuration. QSC Acoustic Linear Phase design ensures the LS218 integrates coherently with other QSC loudspeakers in a shared system, simplifying phase alignment that would otherwise require extensive measurement and DSP tuning. DEEP mode extends low-frequency reach further when the application demands it, and daisy-chain connectivity for analog, Dante digital audio, and AC power via PowerCON TRUE1 accelerates multi-unit deployment significantly.\u003c\/p\u003e\u003cp\u003eSystem control is handled through the QSC SysNav app, enabling design, configuration, monitoring, and signal processing for individual units, full arrays, or grouped subwoofer clusters from a single interface. Native Q-SYS Ecosystem integration via Q-SYS Inventory Extensions positions the LS218 within enterprise-scale AV control architectures. A rugged birch plywood enclosure with Polyurea coating and powder-coated steel grille ensures the cabinet withstands the physical demands of touring and permanent outdoor-adjacent installs. The LS218 is available mid-2026 and backed by a six-year warranty when registered within 30 days of purchase.\u003c\/p\u003e","brand":"QSC, LLC","offers":[{"title":"Default Title","offer_id":53731130638520,"sku":"207038","price":4499.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/207038_QSC-LS218-Dual-18_-Direct-Radiating-Active-Subwoofer-With-Dante_ALT01sqr.jpg?v=1784059413","url":"https:\/\/soundpro.com\/products\/qsc-ls218","provider":"SoundPro","version":"1.0","type":"link"}
