Electro-Voice Evolve 50SB The Electro-Voice Evolve 50SB is the subwoofer component of the Evolve 50 System. Designed to deliver an uncompromising combination of light weight, low‐profile looks, and superior Electro‐Voice audio quality, the EVOLVE50 sets a new performance standard for powered column systems. Consisting of a 15 mm wooden, ported, powered subwoofer enclosure that houses a 12” subwoofer capable of a functional frequency output down to 37 Hz. The bi-directional aluminum pole’s connection to the subwoofer is secured using a magnet, and the column array is gravity-held to the sub pole. The signal is internally routed to the components. The processing engine allows for easy setup via four presets (Music, Live, Speech, and Club), three-band EQ, five user-programmable presets (Store and Recall settings), output delay, phantom power (+15V), visual monitoring of limiter status, input level control and meters, and master volume control to ensure optimal gain structure. The new Electro-Voice QuickSmart Mobile application utilizes Bluetooth Low Energy (BTLE) technology for the wireless configuration, control, and monitoring of up to six EVOLVE 50 systems simultaneously. High resolution Bluetooth audio streaming adds convenience for wireless music playback in breakout rooms, intermission, and musical accompaniment. The perfect choice for DJs, mobile entertainers, bands, singer/songwriters, and any venue where high‐output portable sound is needed — no other column system currently available sounds as good, looks as good, or is as easy to use. The smooth clarity of the EV sound in a sleek new form factor.
