Subwoofer Speaker Review A subwoofer is a type of speaker designed to emit low-frequency sound waves. Suppose a subwoofer is attached to a vertical pole. Of all the energy this subwoofer generates, 75 % of it is emitted forward in front of the suboofer, and 25 % is emitted backwards behind the subwoofer. Suppose a student takes a sound sensor and stands 1.0 m in front of the subwooferand 2.5 m below it. He measures a sound intensity level of...
