The HLA-UB1 is an M/HF loudspeaker specifically designed to extend the projection and HLA Hybrid Line Array and achieve precise under balcony coverage. It can also be used to enhance articulation in other near field applications. A 6” ribbon HF driver with wave guide and four 3.5” MF drivers are employed to match the clarity, detail and program level of other HLA loudspeakers. The enclosure’s shallow depth and minimal height allow easy integration into the architectural environment.
