Direct Radiator

A loudspeaker that doesn’t have a horn between the moving element and the air. Often direct radiator-type speakers are designed for home use, while horn-type speakers are preferred for sound reinforcement applications. Direct radiators generally provide smoother, more uniform response, while horns are much more efficient, providing a greater output level for a given power input. Also, horns have greater directivity, which is usually desirable in sound reinforcement systems.
