Meyer Sound UMS-1P UltraCompact Powered Subwoofer

Description

An extremely compact, self-powered system, the UMS-1 Pultracompact subwoofer provides powerful low-frequency extension in applications where both excellent audio quality and an unobtrusive cabinet size are required. The system’s output is 123 dB linear peak SPL within its operating range of 25–160 Hz. Although designed primarily as a companion for MeyerSound’s UPM-1P wide coverage and UPM-2P narrow coverage ultracompact loudspeakers, the UMS-1P is equally adaptable for use with other Meyer Sound models, such as the HD-1 high-definition studio monitor. The UMS-1P may be used singly or stacked to provide even greater low-frequency output. The tuned bass-reflex enclosure houses two 10 in cone drivers, each powered by a dedicated channel of an integral class AB/bridged power amplifier with complementary MOSFET output stages. Total peak power is 800 watts. Each channel incorporates a limiter that prevents driver over-excursion and regulates the voice coil temperature. A smooth limiting characteristic effectively protects the drivers without the compression effects imposed by typical limiters, allowing high output levels across the drivers’ entire frequency range. The internal electronics also provide active signal processing, including phase correction circuitry that delivers flat frequency and phase response over the entire operating range. Integrating a built-in low-pass crossover while accepting a full-range signal, the UMS-1P’s input allows for simple daisy-chain signal distribution and eliminates the need for external crossovers
