Available in four sizes, the Desono™ ENT203 models have been expertly engineered to serve the wide range of applications routinely encountered by professional sound contractors. Possessing advanced features, highly-focused dispersion patterns, weather-resistant construction, and most importantly sonic excellence, ENT200 columns make installations not only fast and simple, but as functionally effective as possible. The smallest of the ENT200 columns, the Desono ENT203, and is an excellent choice when sonic clarity and predictable directional control are required from a diminutive and unobtrusive loudspeaker system. The ENT203 employs three high-power LF cone drivers and one CRE (Compact Ribbon Emulator) HF tweeter array in a two-way, single-amped configuration. Typical applications include music and speech reinforcement for small houses of worship, hotel meeting rooms, transit stations, background and foreground music for hotels, resorts and themed attractions, and much more. Additionally, the ENT203 complements and supports larger loudspeakers when used for delay fill or area fill, particularly in reverberant environments where controlled directivity is vital for intelligibility.
