Product Overview
The Biamp Desono ENT-LF is a passive ENTASYS low-frequency column loudspeaker that extends low-frequency pattern control in modular line-source arrays. It is designed to assemble with ENTASYS full-range columns to deliver high output and consistent coverage in reverberant spaces. This column loudspeaker suits houses of worship, auditoriums, and large multi-purpose spaces needing intelligible speech and quality music. Primary keyword: ENTASYS column loudspeaker; long-tail: low-frequency line-array column, passive install column speaker, reverberant-space loudspeaker.
Product Description
The Desono ENT-LF is a low-frequency column in the same enclosure size as the ENT-FR, designed to extend low-frequency pattern control while minimizing overall system cost. As a modular true line source, an array of nearly any length can be assembled; longer arrays reduce sound reflections, lower reverberation, and increase speech intelligibility. The ENT-LF is suited to medium-to-large highly reverberant spaces and is equally at home in indoor and outdoor direct-exposure applications, with a wide range of mounting brackets available. It carries an IP54 rating per IEC 60529 and includes an ABS rain cover, and an integrated T-Bar mounting bracket ships with each column. Biamp recommends the Community ALC1604D amplified loudspeaker controller for this product.
Key Features
- Modular line-source design — Columns assemble into arrays of nearly any length for versatile coverage free of unwanted lobes.
- Extended LF pattern control — Six 3.5-inch drivers with optimized spacing extend the narrow vertical beamwidth into lower frequencies.
- High output and intelligibility — Provides high output with highly intelligible voice reproduction and good musical sound quality.
- Weather-rated build — An IP54 rating per IEC 60529 with an included ABS rain cover supports indoor and direct-exposure outdoor use.
- Integrated mounting — An integrated T-Bar mounting bracket is included with each column, with many optional brackets available.
Typical Applications
- House of worship
