The UBX Series from Renkus-Heinz delivers the precise coverage, high intelligibility, and renowned sound quality of our flagship ICONYX loudspeakers into the realm of passive column arrays.
Passive UniBeam™ Technology
New for the UBX Series is our Passive UniBeam™ Technology which addresses each transducer with specially designed all-pass filter networks, gain shading, and additional frequency filtering in order to generate an asymmetrical vertical dispersion with constant directivity, delivering consistent front-to-back coverage with minimal side-lobe artifacts.
Compact Size, Powerful Performance
The UBX Series utilizes state of the art neodymium 3” full-range drivers which allow for an incredibly small footprint. The narrow cabinet, combined with Passive UniBeam™ coverage, allows for plumb surface mounting via the included wall mount bracket, resulting in the least possible architectural intrusion.
Ready for Anything
With EN 54-24 certification, UBX Series loudspeakers are engineered according to the EU’s stringent standards for life safety voice alarm systems, making them perfect for transportation venues, congress halls and museums, and other large hospitality or themed event spaces. Research has shown that during emergencies, voice messaging is more effective than traditional alarms to evacuate people quickly and safely.
All models in the UBX Series are weather resistant (IP64) out of the box with the included gland nut protected input cover and feature high-quality audio transformers for 70V/100V constant voltage operation in large, distributed audio systems.
