Passive radiator (speaker): Applications, Design considerations & Overview

A speaker enclosure using a passive radiator usually contains an "active loudspeaker" (or main driver), and a passive radiator (also known as a "drone cone"). The active loudspeaker is a normal driver, and the passive radiator is of similar construction, but without a voice coil and magnet assembly. It is not attached to a voice coil or wired to an…
