Meyer Sound UPJunior Powered Loudspeaker

This item will only be sold in pairs

Meyer Sounds UPJunior ultracompact VariO loudspeaker brings the sonic signature, versatile rigging, and extraordinary power-to-size ratio of the UPJ-1P to a smaller package. The UPJunior combines the advantages of a self-powered system with the placement and arraying flexibility afforded by a VariO rotatable horn. Though remarkably compact and lightweight, the UPJunior delivers a robust peak power output of 126 dB SPL at 1 meter, making it suitable for use as either a single, primary loudspeaker or within multicabinet horizontal and vertical arrays. Applications include AV presentations; small- to medium-sized main sound reinforcement systems; fill, delay, and effects systems; under-balcony coverage; and distributed systems. The UPJunior was bred for flexibility whether oriented vertically or horizontally. The VariO horn allows quick rotation to provide an 80-degree by 50-degree coverage pattern in either the horizontal or vertical plane. In size, weight, and output, the UPJunior integrates seamlessly with the UltraSeries UPM and UPJ loudspeakers. The UPJuniors low-mid frequency section employs an 8-inch neodymium magnet cone driver, while the high-frequency section utilizes an efficient 0.75-inch exit, 2-inch diaphragm compression driver. Strategically placed metric M8 threaded points allow simple mounting using either eyebolts or third-party pole assemblies.
