Included in kit: - Ferrotec APG L11 synthetic ester-based ferrofluid for speaker applications
- 300uL ferrofluid for two 1" voice coil tweeters
- Absorbent paper strips for removing old ferrofluid
- Detailed instructions
- Material safety data sheet
A 1" voice coil tweeter requires approximately 100uL of ferrofluid. In general, the air gap should be 75% filled prior to inserting a voice coil diaphragm assembly. Ferrofluid improves the performance of high frequency and midrange drivers. It works by damping the impedance at resonance to effectively lower distortion and increase 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.
