Designed for sound reinforcement applications requiring minimum size, the UPM-1 delivers high sound pressure levels with very low distortion and extremely even coverage in both axes. Suitable for a wide range of applications from music playback and delay fill systems to stage monitoring, the UPM-1 features outstanding low-frequency performance in an unusually compact package. Its ultraflat frequency response simplifies room equalization requirements and ensures high gain-before-feedback. The loudspeaker consists of two 5-inch low-frequency cone drivers in a vented enclosure, and a 2 by 5-inch horn-loaded piezoelectric high-frequency driver with passive crossover.
The rugged cabinet is easily handled and installed. It has three 3 ?8\”-16 threaded rigging points, and may be mounted on a stand. An optional steel bracket facilitates mounting in permanent installations. The UPM-1 system requires a high quality professional power amplifier capable of delivering 125 watts continuously into 16 ohms, with a signal voltage gain of 20 dB (minimum) to 30 dB (maximum).
Dimensions (per speaker): 7x8x18 / 14 lbs
