The externally powered UMS-1XP is an extremely compact subwoofer that provides powerful low-frequency extension. The UMS-1XP offers the same 127 dB peak SPL output and 25 Hz to 160 Hz operating range as the UMS-1P while also offering all the advantages of external DC power, making it an ideal solution for installations where AC cabling is not feasible. Powering the UMS-1XP from an external MPS power supply affords the flexibility of lengthy cable runs without conduits.

The UMS-1XP is a logical companion to any of Meyer Sound's externally powered loudspeakers. For installations requiring even greater low-frequency headroom, multiple UMS-1XPs can be stacked.

A tuned, bass-reflex enclosure houses the UMS-1XP's two 10-inch cone drivers. The drivers are powered by two channels of Class-D amplification yielding a total peak power output of 450 watts. Each driver channel includes a limiter that prevents overexcursion and regulates voice coil temperatures, ensuring smooth limiting characteristics and high output levels across the subwoofer's entire frequency range.

The UMS-1XP receives DC power and balanced audio from a single loudspeaker connector, available as a Phoenix 5-pin male, sealed SwitchCraft EN3 5-pin male, or sealed ECO-M 7-pin male. The use of composite multiconductor cables (such as Belden 1502 or equivalent) allows a single cable to carry both DC power and balanced audio to the UMS-1XP. The loudspeaker's amplifier and signal-processing circuits store DC power and tolerate voltage drops, thereby accommodating light-gauge cables and lengthy cable runs.

UMS-1XP subwoofer systems require an MPS-488HP external power supply. The rack mount multichannel power supply can deliver DC power and balanced audio to eight UMS-1XP subwoofers at cable lengths up to 150 feet with just 1 dB of loss in peak SPL using 18 AWG wire. Longer cable runs are possible with heavier wire gauges.

The UMS-1XP's durable enclosure is constructed of premium birch plywood and coated with a black- textured, hard-shell finish. A powder-coated, hex- stamped grille with black mesh protects the unit's drivers. The cabinet top includes a 1 3/8-inch receptacle for pole-mounting the UPM-1XP or UPJunior-XP with the optional MPS-UMS stand. The UMS-1XP is also available from the factory with threaded end plates and the UMS-SM U-bracket for single-mount configurations. Custom color finishes are also available for installations with specific cosmetic requirements.

UMS-SMXP Single Mount Version

The UMS-SMXP subwoofer is a version of the UMS-1XP subwoofer with threaded end plates for single-mount configurations with the UMS-SMXP U-bracket. The UMS-SMXP end plates are factory-installed (with the U-bracket) and not available as an upgrade option for the UMS-1XP. The UMS-SMXP retains the same acoustical and electrical characteristics of the UMS-1XP.
