MEYER SOUND UPJunior: Ultra-Compact VariO Loudspeaker

Meyer Sound’s 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 Meyer Sound UPJunior combines the advantages of self-powered systems with the placement and arraying flexibility afforded by a VariO rotatable horn. Though remarkably compact and lightweight, the Meyer Sound UPJunior produces a robust peak power output of 126 dB SPL at 1 meter, making it suitable for use either singly as a primary loudspeaker or in multi-cabinet horizontal or vertical arrays. Applications include A/V presentations, small- to medium-sized main sound reinforcement systems, fill, delay, effects, under-balcony or under-canopy coverage and distributed systems.


  • Exceptional fidelity and power to size ratio
  • Surprising power capability in a compact package
  • Extraordinarily flat amplitude and phase response for tonal accuracy and precise imaging
  • Constant-Q horn affords uniform response throughout coverage area
  • Predictable and consistent performance ensures system design flexibility
  • Rotatable VariO horn provides versatile coverage options, whether loudspeakers are oriented horizontally or vertically


  • Portable and installed audio-visual systems
  • Theatrical sound reinforcement
  • Front and under-balcony fill
  • Conference centers, presentations, ballrooms and houses of worship
  • Stage Monitoring (with optional MAAM Adapter)


Rotate the horn to change the coverage while maintaining the orientation of the cabinet.

Alter the orientation of the cabinet while maintaining the coverage pattern.

The Meyer Sound UPJunior was bred for flexibility: whether oriented vertically or horizontally, it can provide narrow, targeted coverage or wide coverage, with a simple turn of the VariO rotatable horn, changing its 80° x 50° coverage pattern between the horizontal and vertical planes. In size and weight, the Meyer Sound UPJunior fits into the UltraSeries between the Meyer Sound UPM and Meyer Sound UPJ series loudspeakers.

The cabinet incorporates aluminum end plates that provide unprecedented mounting, flying, and arraying flexibility. Strategically placed metric M8 threaded points allow simple mounting using either eyebolts or third-party pole assemblies. QuickFly rigging options including the MAA-UPJunior array adapter (also used when laying the cabinet horizontally for use as a stage monitor), MLB-UPJunior U-bracket, and the MYA-UPJunior mounting yoke assembly. Other options include weather protection and custom color finishes for applications requiring specific cosmetics.

The UPJunior horn coverage is imprinted on the horn lip for easy reference.


The low-mid frequency section of the Meyer Sound UPJunior 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. Both drivers are designed and manufactured by Meyer Sound in Berkeley, California.

As a self-powered loudspeaker, the Meyer Sound UPJunior incorporates a two-channel, class AB/bridged power amplifier and sophisticated control circuitry housed within the cabinet, dramatically simplifying setup and installation. The UPJunior’s on-board amplifier delivers 300 watts of total burst power. The optional RMS™ module allows comprehensive monitoring of all key system parameters from a Windows®-based computer.
