The new CS2.4′s most innovative design feature is a newly designed coincident tweeter/midrange driver array where the two drivers’ diaphragms share the same voice coil. This technique allows for the elimination of the midrange/tweeter section of the electrical crossover network as the drivers incorporate a mechanical crossover. Along with eliminating the need for two driver magnet structures, these reductions allow the CS2.4 to achieve a level of sonic performance normally reserved for more expensive speakers. The coincident array also uses very powerful neodymium magnets to improve efficiency and a redesigned magnet venting system to reduce unwanted resonances.
The CS2.4′s 8-inch woofer uses a very low distortion short coil/long gap motor system, powered by a 2.5 pound magnet. The rigid aluminum diaphragm eliminates resonance coloration, a special copper pole sleeve reduces inductance distortion, and a heavy copper ring maintains an ultra-stable magnetic field. In combination with the 7.5 x 11-inch bass radiator, the woofer produces exceptionally clean bass down to 33Hz.
