Ferrofluid Repair Kit, 100uL for 1" Diameter Voice Coil Part # MI-FF100
Ferrofluid 100uL General Purpose
  • Ferrofluid Repair Kit
  • 100uL for 1" voice coil
  • Reduces distortion
  • Increases power handling
  • Comes complete with cleaning strips and instructions
  • For most compression drivers, repairs, and diaphragm assemblies


    Our ferrofluid kits come with pre-measured packets of ferrofluid which are used to replace the old fluid in speaker air gaps when replacing diaphragm and coil assemblies.
    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.

    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. The kits listed are approximate fill quantities relative to approximate voice coil diameters. 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. Adding ferrofluid to a driver not intended for it will, in most cases, void the original manufacturer's warranty. Included in kit: A ferrofluid packet, absorbent paper strips for removing old ferrofluid, detailed instructions, and material safety data sheet.

I had a speaker with low output from the tweeter and replacing the ferrofluid fixed the problem!
