Column Array Speakers Description

Clear Classroom Audio—From the Front Row to the Back

The TeachLogic® SP-5000 Column Array Speakers distribute the teacher’s amplified voice more evenly throughout the classroom, helping students hear clear, intelligible instruction from more locations in the learning space.

The SP-5000 uses four vertically arranged 2.5-inch drivers to create wide 120° horizontal coverage with controlled 20° vertical dispersion. This design directs sound across the student listening area while limiting sound toward ceilings and floors, where reflections can interfere with speech clarity.

Supplied as a matched pair, the SP-5000 gives schools an efficient way to create consistent classroom sound coverage with two strategically positioned speakers.
