Cables To Go classroom speakers are 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 line of speakers is offered in both wall mount and ceiling mount configurations to meet the needs of different classroom designs. Available in industry standard 8 Ohm and 70 volt versions, these speakers ensure long life and quality sound. The Cables To Go Classroom Speakers integrate seamlessly with the TruLink Audio Amplifier to provide a complete classroom sound system. Additionally, the speakers can be combined with the TruLink A/V controller and RapidRun for a complete connected classroom.Ceiling speakers mount easily for a clean, unobtrusive look while dispersing sound down to students at 125 degrees for full classroom coverage. 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.
