Digital and Electronic Device Design Electro-Voice ZLX Loudspeaker by TEAMS Design Electro-Voice has an established reputation for being at the forefront of professional audio equipment. The design of their products, however, was not reinforcing that story. The design team found that users wanted a speaker with great sound, user-friendly features, and style that would represent them well as professionals. To convey the brand's strength, the silhouette has a dynamic angularity; the durable enclosure is marked by a brick-like pattern. Since musicians, DJs, and performers regularly transport and mount their speakers, 3 over-molded handles offer multiple grip positions.
