Ferrofluidics offers a number of retrofit kits. These can be used to replace the ferrofluid in speakers, or in some cases retrofitting fluid to speakers originally built without Ferrofluid. Each kit contains a pre-measured quantity of ferrofluid supplied in a ready to use dispenser, absorbent paper for removing any existing ferrofluid and full instructions. Retrofit kits are available for speakers from a wide range of manufacturers. To find out if we have a kit that is suitable for your speaker, call your local sales office.
