Biamp Desono ENT-FR-CTO High-Performance Column Line Source Loudspeaker
The Desono ENT-FR-CTO is a premium three-way column line source loudspeaker designed for permanent installations in demanding acoustic environments. Offering superior performance, high output, and excellent speech intelligibility, it's an ideal solution for auditoria, houses of worship, transportation hubs, conference centers, stadium concourses, and museums.
With its modular and scalable design, the ENT-FR-CTO supports configurations from single units to floor-to-ceiling arrays of any length, ensuring precise coverage and flexibility. Longer arrays effectively minimize reflections and reverberation, greatly improving clarity in medium to large reverberant spaces.
The ENT-FR-CTO is equally at home in indoor or outdoor direct exposure applications, providing consistent reliability and performance. Its modular system also allows installers to customize vertical lobes, either symmetrically or asymmetrically, to achieve highly focused or multi-lobe coverage previously only possible with powered, steered arrays.
For best performance, the Community ALC1604D amplifier is recommended, with support for higher-power ALC models where additional headroom is required. Combined with a wide selection of mounting brackets, the ENT-FR-CTO delivers architecturally refined, flexible, and professional-grade sound reinforcement for the most challenging environments.
