Desono ENT-LF offers superior performance, high output and high power handling capability in architecturally appealing enclosures. The scalable design supports configurations of loudspeakers from singles to floor-to-ceiling arrays of any length, meeting the acoustical design needs of nearly any application. The ENT-LF is a low frequency column in the same size enclosure as the ENT-FR, and is designed to extend low frequency pattern control while minimizing overall system costs.

ENT-LF is most beneficial in medium to large highly reverberant spaces. As a modular true line source, an array of nearly any length can be assembled. Longer arrays minimize sound reflections, reducing reverberation and increasing speech intelligibility. The ENT-LF is equally suited for indoor and outdoor direct exposure applications. A wide range of mounting brackets is available to fit nearly every installation.

Community ALC1604D is recommended for this product. Higher power ALC models may be used safely as well.

  • Modular design for versatile coverage, free of unwanted lobes
  • Wide frequency range and high output level
  • Highly intelligible voice reproduction and excellent musical sound quality
  • Simple installation using a variety of versatile mounting accessories
  • Integrated T-Bar mounting bracket included with each column
