25mm Magnesium Dome Treble
The Magnum is a 25mm high definition magnesium dome treble with a patented Neodymium based magnet system and is the tweeter of choice for those who seek extremely precise and realistic sound reproduction combined with a relatively low crossover frequency.
The unique Hexadym magnet system which uses 6 radially magnetised NdFeB magnet blocks is combined with an optimally shaped magnesium dome membrane, which behaves like a piston throughout the audible frequency range and shows controlled break up above it.
Efficient ventilation and damping of every potential resonant cavity and a generously underhung voice coil ensures that the Magnum achieves low distortion even at low crossover frequencies.
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.
The Magnum is fitted with a 6.0mm injection moulded zinc front plate with a slight loading characteristic, which ensures linear frequency response and a stiff and stable connection to the cabinet. The moulded zinc rear chamber eliminates unwanted resonances and conducts heat away from the magnet system.
