The UB22z provides extra-wide-angled coverage (horizontal) from a wall-mounted position. The ultra-compact loudspeaker provides surprisingly high output and exceptional fidelity for near field applications. Applications as fill/delay elements include large and small theatres and houses of worship. As a main system, they can be built into high definition, distributed systems for use in industrial or retail environments and as standalone or distributed loudspeakers for boardrooms, restaurants, offices, and transportation centers. Foam-backed grilles conceal the drivers, and mounting is very flexible, with optional mounting bracket available.
