A unique HEXADYM magnet system (US Pat 6.020.805 ) based on 6 radially
magnetized NdFeB magnet blocks. Efficient ventilation and damping of every
potentially resonant cavity behind the dome, surround and voice coil. Moderate
magnetic stray fields present no problems in AV installations.

A generously underhung voice coil ( + and - 0.5mm ) ensures low distortion even
with low crossover frequencies.

An optimally shaped and coated fabric dome diaphragm manufactured by SEAS
from SONOTEX for excellent performance and consistency.

Flexible lead-out wires ensure a good connection between voice coil and terminals.
This arrangement also helps to prevent lead breakage due to the large excursions
encountered when low crossover frequencies are used.

A 6,0 mm injection moulded zinc front plate with a very slight loading characteristic
which ensures linear frequency response, and a stiff and stable connection to the
cabinet. A substantial injection-moulded rear chamber made from zinc eliminates
unwanted chamber all resonances and conducts heat away from the magnet system.
