Description
The ETON 3-312/C8/25 HEX SYMPHONY II 3" bass-midrange driver with midrange preference, phase-plug construction and 3-layer hexacone sandwich cone has spatial and open reproduction for uncolored sound performance.
The Hex Symphony II series is the logical further development of our successful, patented Symphony I series.
ETON's entire know-how has gone 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 inner structure. Maximum rigidity and an excellent internal absorption effect are thus guaranteed. The hand-applied coating also supports the neutral behavior of the cone and gives the surface an optical depth.
The Symphony II midrange and bass 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 drivers 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 mini[1]mum compression effects at high amplitudes.
