Classroom Sound System with Drop Tile In Ceiling Speaker and the TeachLogic Forum

Need a low-cost classroom presentation system? The TeachLogic Forum with Pure Resonance Audio® SD4 is the answer. 

The Forum features two wireless microphone channels, two auxiliary inputs and two separate outputs. 

These features provide

  • the freedom to move around the classroom, 
  • the ability to easily integrate technology in the classroom,
  • the ability to provide assistive listening and
  • the ability to record audio.

The Pure Resonance Audio® SD4 uses four angled 6.5" speakers to distribute audio evenly throughout the classroom. By replacing one large paper cone speaker with four aluminum speakers, the SD4 maximizes intelligibility while still producing full range sound. There is no other in ceiling speaker like it.
