The Meyer Sound UMS-1P UltraCompact 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 Meyer Sound’s UPM-1P wide coverage and UPM-2P narrow coverage ultra-compact 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.
