Meyer Sound UPJUNIOR-WP-3, 8" 2-Way Active Speaker, Weather Protection, 3-Pin Input

The Meyer Sound UPJUNIOR-WP-3 is an ultracompact VariO™ loudspeaker brings the sonic signature, flexible rigging, and extraordinary power‑to‑size ratio of the award-winning UPJ-1P to an even more compact package perfectly suitable for a broad range of applications. The Meyer Sound UPJUNIOR-WP-3 combines the advantages of self-powered systems with the placement and arraying flexibility afforded by an 80° x 50° VariO rotatable horn and QuickFly® rigging. Though remarkably compact and lightweight, the UPJunior delivers a linear peak SPL of 123.5dB with 18.5dB crest factor, making it suitable for use as either a single, primary loudspeaker or within multi-cabinet horizontal and vertical arrays. Meyer Sound designed the Meyer Sound UPJUNIOR-WP-3 for flexibility. Whether oriented vertically or horizontally, its easily rotatable VariO horn facilitates the optimum horizontal and vertical coverage in any situation.
