Product Overview
The Biamp Desono ENT-FR is a passive full-range 3-way ENTASYS column line-source loudspeaker, finished in White. Its scalable modular design supports configurations from single columns to floor-to-ceiling arrays, delivering high output and excellent speech intelligibility. It is engineered for permanent installation in auditoriums, houses of worship and large commercial spaces, including highly reverberant rooms. As a true line source, it minimizes reflections to improve intelligibility in challenging acoustics.
Product Description
Desono ENT-FR offers high output and power handling in an architecturally appealing column enclosure. It is most beneficial in medium-to-large, highly reverberant spaces; as a modular true line source, arrays of nearly any length can be assembled, with longer arrays reducing reverberation and increasing speech intelligibility. The system is modular, allowing the installer to center the vertical system lobe symmetrically or asymmetrically about the column array's vertical axis. Multiple ENT-FR columns can create single-lobe focused coverage, or tall arrays combining FR and LF columns can create multiple independent vertical lobes. The ENT-FR is suited to indoor and outdoor direct-exposure applications, and a wide range of mounting brackets is available; Community ALC1604D is the recommended amplified loudspeaker controller.
