Positioned above the ZLX series and below the EKX series, the new Elx200 series includes 10 in., 12 in., and 15 in. two-way models, and 12 in. and 18 in. subwoofers. All of them are available in powered and passive versions. This is the passive 18 in. subwoofer. The Elx200 series, introduced in 2017, zeroes in on an underserved price point and does so with lightweight cabinets, professional sound and a versatile feature set that makes playing and performing easier than ever. This model is an ideal choice for bands, DJs or venues that use dedicated power amps. The 18 in. woofer provides every bit of the low-end punch a dance audience demands.The full-range models feature low-profile form factors designed with durable composite enclosures to balance light weight, structural integrity and ease of use. The subwoofers pack powerful low-frequency output into a compact footprint, assembled in an optimized 15mm-thick wooden enclosure with a protective finish. The features that have made other members of the Electro-Voice portable loudspeaker family a go-to for first-rate sound quality are also present, including powerful-yet-efficient Class-D amplifier design, Quick Smart DSP control and processing, and SST (Signal Synchronized Transducers) waveguide design. Whether you are adding subwoofers to an existing system or building your system from the ground up, Elx200 offers an economical, professional solution to the challenges of live sound reinforcement.
