From the Ferrotec website:
"Ferrofluid improves the performance of high frequency and midrange drivers.
It works by damping the impedance at resonance to effectively lower distortion,
smooth frequency response, and increase thermal power handling. It should be used to replenish
drivers treated previously with ferrofluid.
With care, it can also upgrade most drivers that have never contained ferrofluid.
In general, the air gap should be 75% filled prior to inserting a voice coil diaphragm assembly.
The kit contains synthetic ester-based ferrofluids and in most cases should not pose any adhesive incompatibility.
It is recommended that this is confirmed by contacting the driver manufacturer prior to usage.
Ferrofluid enables audio speakers to function more efficiently, with improved audio response and better power handling.For audio speaker manufacturers, ferrofluid also provides significantly better speaker manufacturability for improved quality and higher manufacturing yields."
Good Luck
Still NOT convinced ? That's NOT a problem.
