The most common type of driver uses a lightweight diaphragm connected to a rigid basket, or frame, via flexible suspension that constrains a coil of fine wire to move axially through a cylindrical magnetic gap.
The lowest-priced speaker systems and most drivers are manufactured in China or other low-cost manufacturing locations. Although the manufacture of drivers has become largely commoditized, the fabrication and subsequent sale of finished speaker systems still carries high profits. Partly for this reason, manufacturers are increasingly combining power amplifier electronics (a typically lower profit item) with finished speaker systems to create powered speakers with an overall higher market value.[citation needed]
