The Rauland USO188 Speaker is especially suited for use in classrooms or in small areas where quality music distribution is desired. The use of a hard fibber “whizzer” cone provides extended high frequency response with exceptional clarity, while the molded fiber moisture-resistant main cone delivers excellent mid and low range frequency response. The USO188 speaker features rugged construction; with its heavy-gauge metal basket it offers superior protection against shock and aging deterioration
