It’s easy to build your live sound system around the ELX118P. It features an XLR/TRS combo input, switchable EQ modes that toggle between Normal (for typical situations) and Boost (for applications that need enhanced bass), and an indicator light that lets you know when the built-in limiter is working too hard, so you can optimize your levels. The ELX118P also links effortlessly to a speaker or another sub via a simple Link Output jack. The Electro-Voice ELX118P is built from top-quality components. Its 18″ woofer yields a 32Hz-130kHz frequency range with a maximum SPL of 134dB. And although this powered subwoofer pushes enough air to reach the back row of your venue, its efficient Class D amplifier runs cool without fans. Electro-Voice designed their ELX Series with DJs, musicians, and rental companies in mind. These streamlined speakers provide you with everything you need and nothing you don’t. And they sound great, employing top-quality electronic components and warm-sounding wood enclosures. At Sweetwater, we’ve found that ELX Series speakers are great for a wide array of portable sound applications, and their straightforward controls make attaining excellent results easy.
