To adequately reproduce a catholic range of frequencies, most loudspeaker systems beg bounteous than one driver, particularly for high safe pressure identical or lanky accuracy applications. Individual drivers are familiar with to cover distant frequency ranges. The drivers are named subwoofers (very crouched frequencies), woofers (low frequencies), mid-range speakers (middle frequencies), tweeters (high frequencies) and sometimes supertweeters which are drivers optimized for Wireless Speakers exceptional frequencies than a normal tweeter.

The basket or frame must be mediated for rigidity to avoid deformation, which will silver the magnetic conditions in the magnet gap, and could even genesis the voice coil to pat against the walls of the magnetic gap. Baskets are typically cast or stamped metal, although molded plastic baskets are becoming common, especially for inexpensive drivers. The frame also plays a considerable role in conducting warmth away from the coil.
