Beschreibung
The ETON 3-312/C8/25 HEX SYMPHONY II 3" bass-midrange driver with midrange preference, phase plug construction and 3-layer hexacone sandwich membrane has spatial and open reproduction for an uncolored sound performance.
The Hex Symphony II series is the logical development of our successful, patented Symphony I series.
All of ETON's know-how went into the development of the Symphony series.
The specially patented production process made it possible for the first time to use a three-layer sandwich construction in combination with aramid fibers and their hexagonal internal structure. This ensures maximum rigidity and an excellent internal absorption effect. The hand-applied coating also supports the neutral behavior of the membrane and gives the surface an optical depth.
The Symphony II midrange and woofer drivers produce a unique sound spectrum that is typical of Hex. The sound characteristics are harmonious, gentle reflections of the overtones and pronounced, light mids. A precise and powerful bass is produced in the low frequency range. All Symphony II chassis are characterized by a high degree of musical imaging and an impressive sound image.
The special design of the ferrite magnet geometry ensures an almost perfectly symmetrical magnetic field. The multiple ventilation and the flow-supporting cast basket guarantee minimal compression effects at large amplitudes.
