It is the first in an entirely new approach to Accuton speaker design, featuring the 4D (Direct Dome Drive Design) concept, which provides the shortest distance between voice-coil winding and dome. The spider is not connected to the voice-coil former anymore, thus removing 15mm of unnecessary former length. The result is an extremely true reaction of the dome. The low loss rubber surround is connected to the voice-coil former, preventing any kind of interaction with the dome. An open fabric spider centers the dome with a direct connection and high linearity. An ideal acoustical center has been achieved, which is identical with Accuton tweeters. Its novel designed underhung motor does not cover the back-side of the dome, eliminating the chance for reflections and energy storage. Some of its main features include an ideal acoustical center, proprietary 4D concept, no rear reflections, and an underhung motor.
