Meyer Sound USW-112P Self-Powered Subwoofer with 5-Pin XLR
The USW-112P compact narrow subwoofer provides big bass sound for very tight spaces. Its compact rectangular enclosure and slanted connector panel enable flush-mounting of the cabinet against wall surfaces, reducing required installation depth to 12 inches, including connectors. Designed to be the ideal companion to Meyer Sound’s ULTRA-X20, it also complements the low frequencies in other Meyer Sound loudspeakers, such as the UP-4slim and those in the UPM family. The USW-112P has an operating frequency range of 35–140 Hz with a linear peak SPL of 123 dB, measured in half-space at 4 m and referred to 1 m using M-noise. The bass reflex cabinet employs a low-velocity port design for high efficiency and low port distortion.
