The Black Cables To Go 5" 70V Wall Speaker is specifically designed for use in K-12 classrooms to deliver high quality audio from multimedia presentations, video clips, movies and other curriculum throughout the classroom. This speaker integrates seamlessly with the TruLink Audio Amplifier to provide a complete classroom sound system. Additionally, the Black Cables To Go 5" 70V Wall Speaker can be combined with the TruLink A/V controller and RapidRun for a complete connected classroom. Wall mount speakers work best in classrooms with sharp angles or room partitions (alcoves) or in rooms where ceiling mounting is not a practical option. Designed for long life, rubber surrounds and poly cone construction provide a durable solution that will not degrade over time compared with paper/foam constructed speaker components.
