Conference-room speakers should provide even coverage and clear speech at the listening positions without creating excessive sound near the microphones. Ceiling speakers can work well in many rooms, while wall-mounted or directional speakers may be better when the room layout or display position requires more controlled coverage. Speaker selection should consider room size, ceiling height, acoustics, microphone placement, required sound levels and the conferencing system's DSP. The goal is consistent speech intelligibility rather than simply choosing the most powerful speaker.
