Biamp Desono ENT-LF-CTO Low-Frequency Column Line Source Loudspeaker
The Desono ENT-LF-CTO is a high-performance modular low-frequency column loudspeaker designed to extend bass and low-frequency pattern control in scalable line array systems. Housed in the same elegant enclosure as the ENT-FR, it delivers superior output, high power handling, and consistent performance while helping minimize overall system costs.
Perfect for medium to large, highly reverberant spaces, the ENT-LF-CTO excels in applications such as auditoria, houses of worship, transportation hubs, stadium concourses, and museums. Its modular design allows arrays of nearly any length, minimizing reflections and improving speech intelligibility.
Installers can configure vertical system lobes symmetrically or asymmetrically, enabling precise coverage. Combined with ENT-FR units, tall arrays can create multiple independent vertical lobes, previously only possible with powered, steered arrays. A wide range of mounting brackets ensures easy integration in nearly any installation, indoors or outdoors.
For best performance, the Community ALC1604D amplifier is recommended, with higher power ALC models also fully compatible.
