Audio Ferrofluid Loudspeaker Retrofit Kits 900uL - General Purpose for 4" Diameter V.C.
Ferrotec offers Audio Retrofit Kits for loudspeaker reconditioning and retrofitting.
These 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. Many speaker manufacturers offer these kits with their diaphragm and coil replacement 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.
Highlights
- Great for retrofit/replacement or new applications
- Damps impedance at resonance
- Reduces distortion
- Conducts heat away from voice coil
- Increases power handling capacity
- Comes complete with cleaning strips and instructions
- Sized to fit approximate voice coil diameters
Note: This fluid can permanently stain clothing and other material.
Handling Tip: Ferrofluid can be very messy if mishandled or if all safety precautions are notadhered to.
PLEASE NOTE: THESE FERROFLUIDS ARE HYDROCARBON BASED LIQUIDS, COMPARABLE TO MOTOR OIL. DO NOT INGEST !!!
Magnetic Strength and Gauss: Magnetic strength and Gauss ratings can be confusing. Many companies advertise their magnets and magnetic products with the “internal gauss” rating which is very different from the actual “surface gauss”. The surface gauss is dependent on the N-rating, size and shape of magnet. We provide a magnetic force calculator to calculate holding force and gauss at our website. Just type “Frenergy” or “Magnetic Force Calculator” into a search engine like Google and find our website. We have provided the surface Gauss in the item description above and also further technical information in the tables below.
Types of magnets:
There are 5 main types of magnets. Neodymium and Samarian Cobalt are permanent magnets which means they don't lose their magnetism over time like Alnico, Ceramic/Ferrite or Flexible rubber magnets. Neodymium are the strongest however most are rated below 100 degrees C. Some neodymium magnets can tolerate up to 150 degrees C. Samarian Cobalt are the most expensive as shown in the cost comparison and have both high temperature and high strength properties. Ceramic/Ferrite and flexible rubber magnets are the least expensive and also have low magnetic force.
