You gotta block that echo, champ. Hang some heavy drapes on the walls, put acoustic foam where the sound hits first. Keep the stage floor a bit open so the crowd can feel the boom, but line the back wall with those panels so the voice doesn’t bounce too much. Add a few rugs on the floor too – they soak up extra reverb. That way the crowd still gets the power, but the vocal stays clear and sharp. Remember, protection first, then showtime.
