About the EX series

The EX series, incorporating the abundant technological know-how behind Pioneer's flagship TAD speaker series, was developed with the goal of creating the ultimate speaker possible in its price range.

The design and production of the EX series result from an international effort that represents the finest in Pioneer's speaker technology.

Technology behind the S-3EX

CST

The core driver of the system is the Coherent Source Transducer (CST), which draws on the technology used in TAD. The tweeter diaphragm is mounted concentrically within the apex of the midrange cone and provides a point source of sound from 400 Hz to 100 kHz. The CST ensures a perfect spectral balance between the direct and reflected sounds that arrive at the listener's ears, providing a more consistent sound throughout the listening room and improved imaging capability.

Ceramic Graphite Diaphragm

The CST's tweeter features a ceramic graphite diaphragm that provides top-level strength and dampening characteristics that are practically unrivaled by any other available materials currently used in high-end audio speaker systems. Ceramic graphite's lightness and exceptional strength combine to create speakers whose diaphragm resonance can be pushed far beyond their audible range.
