8-212/C8/37 Hex Symphony II

The ETON 8-212/C8/37 HEX SYMPHONY II is an 8" mid-woofer with a 3-layer Hexacone sandwich cone, equipped with a solid bass foundation, fast and crisp bass reproduction, high dynamics even in the lower midrange.

The Hex Symphony II series is the logical evolution of our successful, patented Symphony I series.
The entire expertise of ETON has been incorporated into the development of the Symphony series.

The specially patented production process enabled the three-layer sandwich construction in combination with aramid fibers and their hexagonal internal structure for the first time. Maximum rigidity and excellent internal absorption effect are thus guaranteed. The manually applied coating also supports a neutral cone behavior and gives the surface optical depth.

The Symphony II midrange and woofers produce a unique sound spectrum that is typical for Hex. The sound characteristics are harmonic, smooth reflections of overtones and pronounced, light mids. In the bass range, precise and powerful bass is produced. 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.
