Ferrofluid Kit (300 uL for 1.5" Voice Coil)

I replaced ferrofluid when I replaced a high frequency diaphragm that had been used in a dusty environment. The included instructions were well-written and helpful.

Pulled out some very old and thick ferrofluid out of the voice coil prior to installing the new fluid. Speakers sound much better now.

I am so glad these kits are now easily accessible and priced affordabley.The Vifa tweeters in my old Mission 762i speakers became muddy and dull , reduced sensitivity ect...Using the kit ,cleaning the old sticky sluge out , and refreshing with clean new ferro fluid gave them that same as new speed and sparkle.
