MEYER SOUND UP-4XP : Ultra Compact Loudspeaker

The Meyer Sound UP-4XP ultracompact loudspeaker is ideally suited for applications requiring a small, inconspicuous cabinet that also delivers high sound pressure levels, low distortion, and uniform directional control. The self-powered Meyer Sound UP-4XP offers exceptional audio performance in a compact package with the advantages of a remote power supply. As a standalone loudspeaker, the Meyer Sound UP-4XP can be used for vocal reinforcement, frontfill coverage, and delay coverage for under-balcony applications. The Meyer Sound UP-4XP can also be paired with an optional subwoofer to create a full-range system.


  • Extraordinary fidelity and power capability in an ultracompact package
  • Metal dome tweeter delivers a smooth high-frequency response
  • Wide, symmetrical pattern covers a broad listening area
  • Unique crossover design eliminates combing and yields a consistent midrange response
  • Exceptional SPL to size ratio
  • Supports long cable runs with light-gauge cables


  • Frontfill and under-balcony fill coverage
  • Theatrical sound reinforcement and special effects
  • Portable and installed AV systems
  • Compact voice reinforcement systems

The Meyer Sound UP-4XP boasts a wide operating frequency range of 85 Hz to 18 kHz and a conservatively rated maximum peak SPL of 119 dB, with very low distortion. The unit's high-frequency section includes a 1-inch metal dome tweeter on a constant-directivity, high- frequency horn with a 100-degree beamwidth. The low/mid-frequency section includes two 4-inch cone transducers that work in parallel at low frequencies - delivering a combined acoustic output - with one of the drivers rolling off at higher frequencies to prevent interference (due to comb filtering effects) in the crossover region. The proprietary Meyer Sound UP-4XP drivers, which are manufactured at Meyer Sound's factory in Berkeley, California, are powered by three channels of onboard power amplification that include an active crossover, voltage limiters, and frequency and phase correction circuitry.

Balanced audio and DC power are received by the Meyer Sound UP-4XP from a single 5-pin Phoenix connector on its rear panel. Powering the unit from an external source eliminates the need for wiring conduits while still preserving the advantages of self-powered systems. Meyer Sound's UP-4XP amplifier and signal- processing circuits are designed to store DC power and tolerate voltage drops, thereby accommodating light-gauge cables and lengthy cable runs. Meyer Sound UP-4XP loudspeaker systems require a Meyer Sound MPS-488 external power supply. The rack mount multi-channel power supply can deliver both balanced audio and 48 V of DC power to four Meyer Sound UP-4XP loudspeakers at cable lengths of up to 150 feet, with just 1 dB of loss in peak SPL using 18 AWG wire. The use of composite multiconductor cables (such as Belden® 1502) allows a single cable to carry both audio and DC power to the Meyer Sound UP-4XPs. Longer cable lengths are possible for moderate applications that don't drive the loudspeakers to maximum output, or when using heavier wire gauges for the DC power.

Other options include weather protection and custom color finishes for installations and applications with specific cosmetic requirements. The optional MUB-UP4 U-bracket mounts the loudspeaker on walls and ceilings at adjustable angles.
