A purpose-designed \u003cstrong\u003e18-inch subwoofer\u003c\/strong\u003e in a direct-radiating enclosure is driven by an energy-efficient \u003cstrong\u003e4000W Class-D amplifier\u003c\/strong\u003e with power-factor correction, delivering very high output with headroom for today’s program material. With a rated \u003cstrong\u003e138 dB peak SPL\u003c\/strong\u003e, selectable \u003cstrong\u003eDEEP mode\u003c\/strong\u003e for extended low end, and support for \u003cstrong\u003ecardioid sub array\u003c\/strong\u003e deployments (two or more units), the LS118 delivers clean, controlled bass that focuses energy where the audience needs it. Built on QSC’s Acoustic Linear Phase (ALP) approach, it integrates seamlessly with companion L Class tops for coherent, uniform coverage across the venue.\u003c\/p\u003e\n\u003cp\u003eNetworking and control are first-class. The LS118 provides daisy-chain connections for analog audio, \u003cstrong\u003eDante networking\u003c\/strong\u003e, and AC power via PowerCON TRUE1, while the \u003cstrong\u003eQSC SysNav app\u003c\/strong\u003e (System Navigator) lets you design, configure, monitor, and apply processing to single boxes, arrays, or groups—speeding up setup and repeatable show workflows. Physical deployment is equally flexible: \u003cstrong\u003eM20 pole receivers\u003c\/strong\u003e support vertical or horizontal use and ground-stacking with LA108\/LA112, so a single rig can handle portable PA, fixed install, or production work without rethinking hardware.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003epolyurea-coated wooden enclosure\u003c\/strong\u003e and low-noise casters handle real-world load-ins with a touring mindset—durable, stable, and quiet on the move. For engineers and integrators, the combination of ALP voicing, network interoperability with Q-SYS via inventory extensions, and app-based control makes the LS118 an efficient, scalable low-frequency foundation. Pair one for compact systems, run multiples in \u003cstrong\u003eline array\u003c\/strong\u003e ecosystems, or build cardioid clusters to keep stages cleaner and neighbors happier. LS118 is the L Class sub that trades gimmicks for usable power, robust connectivity, and fast deployment.\u003cem\u003e\u003c\/em\u003e\u003c\/p\u003e","brand":"QSC","offers":[{"title":"Default Title","offer_id":50881191379222,"sku":"LS118","price":2999.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0724\/7622\/9910\/files\/1728310813_1752584.jpg?v=1770157916","url":"https:\/\/store.ave.tech\/products\/qsc-ls118-4000w-next-generation-intelligent-active-18-subwoofer","provider":"AVE Store","version":"1.0","type":"link"}
