The T25CF001 is a 25mm fabric dome with moderately high efficiency.
An optimally shaped dome and a wide SONOMEX surround, both manufactured by
SEAS, ensure excellent performance and consistency.
Low viscosity magnetic fluid which provides excellent cooling while maintaining a low resonance frequency.
6 mm solid metal front plate with a slight loading characteristic which ensures
linear frequency response, and a stiff and stable connection to the cabinet.
A substantial injection-moulded rear chamber, with complex internal shape and
reinforcing ribs, which eliminate unwanted chamber resonances and reflections.
A double magnet system which increases sensitivity and provides better control of the voice coil.
This system also reduces the magnetic stray fields, making the T25CF001 an ideal choice in high end A/V applications.
