Can magnetic fluid be added to the horn voice coil?

Magnetic liquid can reduce the working temperature of voice coil, improve the power bearing capacity of speaker, improve the frequency response of speaker, help voice coil keep the center position, reduce harmonic distortion and power compression effect, improve dynamic performance and prolong the service life of speaker.

Magnetic fluid (perhaps called ferrofluid or magnetic fluid) is a brownish-black liquid magnet, which is formed by ultrafine magnetic particles with a diameter of about 10 nm suspended in a synthetic oil carrier.
