    Unsolved Matching amplifier power for column speakers in a meeting room

    4x3 inch full frequency column speakers 2x350W Class D Amplifier 4x350W Class D Amplifier
    South Africa


    For a medium meeting room, we plan to use 4x3 inch full frequency column speakers.

    Would a 2x350W Class D Amplifier be enough, or should we choose the 4x350W Class D Amplifier?

    The room is around 90 square meters, mainly speech reinforcement, not music.

      For a ~90 m² room used mainly for speech, a 2×350W Class D Amplifier is enough — it drives two 4×3 inch full frequency column speakers (one per channel) with plenty of headroom.

      You only need the 4×350W Class D Amplifier if you plan to run four speakers (for example two zones, or two front and two rear). Since your use case is speech reinforcement and not music, the 2×350W is the more appropriate and cost-effective choice.
