CHASSIS CONSTRUCTION

Optimised in the design process using finite element analysis (FEA) to provide maximum strength, resistance against thermal and other external forces. The majority of Fane chassis are made of high grade die-cast aluminium. Our selected material has the specific advantages of high strength and tensile stress factors, high strength-to weight ratio, low thermal expansion factor, high thermal conductivity factor, non-magnetic, highly resistant to corrosion and finished in high quality black enamel with heat treatment for permanent durability in varying environments.

FORCED AIR AND ASSISTED COOLING

The active motion of the cone and suspension creates airflow within the motor structure. Optimised air channels and vents are designed into the motor structure and chassis designs. This allows heat to be extracted efficiently by allowing the air flow to be forced through the channels and vents, keeping the voice coil and motor structure temperature under control. This in turn enhances power handling capabilities and minimises power compression effects.

VOICE COILS AND FORMERS

We have in excess of forty different former materials at our disposal, each coil is designed with the former characteristics in mind. Not all designs work well with a standard former material. To optimise designs, in addition to standard copper, various other wire materials and application techniques are specified such as aluminium, Copper Clad Aluminium Wire (CCAW), silver, square wire, multi-layer and edge winding.

INSIDE/ OUTSIDE WINDINGS VOICE COILS

Fane have used this technology for a number of years. Not all designs benefit from this method of winding, and again, each product is designed with an optimised voice coil geometry. Inside outside windings offer a balanced coil and increased heat dissipation resulting in lower power compression.

VENTED VOICE COILS

Vented voice coils are used to minimise air turbulence within the motor and voice coil assembly. The correct spacing, size and position of these vents all effect the efficiency and heat dissipation achieved when this technique is used. Each of our product designs has had special attention in this area during development, a vented coil is only specified if it benefits the optimised design.

MOTOR ASSEMBLY MATERIALS

Fully optimised, Finite Element Analysis (FEA) motor structure designs ensure the highest possible magnetic flux from minimum mass.

CONE, SURROUND AND DIAPHRAGM MATERIALS

We work in close collaboration with the worlds leading cone, surround and diaphragm manufacturers, from Germany, UK and USA. This ensures that our products are always designed using the latest and most trusted cone pulp formulas and developments in material technology. Our product designs are optimised with specific cone, surround or diaphragm materials and pecifications in mind. If the right component doesn’t exist in our extensive arsenal then we will develop one suited to the design requirements.

SUSPENSION MATERIALS

Suspension systems are a highly important part of our design and development process. By taking the time to ensure the correct materials are used, optimises not only the drivers behaviour and TSP parameters, but also the tonal character of the driver. It is our objective to use materials that are ‘well behaved’ offering longevity and linearity under extreme pressure. For this reason we have in excess of 10 principle materials we use and trust.

SPECIALIST CONE COATINGS

Fane offer a range of cone treatments and coatings that are pre-applied during the cone manufacturing process, these are an integral part of the materials design specification. These coatings offer tonal character changes, dampening, weather proofing, water proofing and fire retardant properties. Coatings applied post-manufacture are also available within our production facility.

COMPRESSION DRIVER PHASE PLUGS

Individually precision machined and hand assembled. Three slot, optimised geometry phase plug design enhances tonal performance while minimising sound wave cancellations throughout the working bandwidth.

POWER RATINGS AND PARAMETERS

Fane measure power ratings according to the AES standard protocols. Each speaker is tested for 2 hours at rated power over the working bandwidth of the driver, after which the driver should show no appreciable damage. Fane also takes into account the mechanical properties of the driver when classifying power ratings even though the electrical properties of the voice coil can often exceed the rated power of the driver.
