All driver designs have been specially developed, from the ground-up for the Concept Series. Each driver is optimised to deliver a neutral, powerful and dynamic audio, free from exterior and interior resonances that can affect the transparency of sound. New innovations on the Concept 30, 50 and 90 include a hermitically sealed and decoupled tweeter enclosure to shield from internal resonances from the mid/bass driver and reduce distortion, a driver assembly baffle-mounted design to dampen vibrations, while a larger mid/bass driver voice coil increases motor strength resulting in a 50% increase in power handling.
