• Voice coil: edgewound copper wire with high
temperature bonding strength. Polyimide fiber glass
former able to withstand high temperatures.
• Cone: paper cone capable to endure the most extre-
me conditions.
• Surround: treated cloth to assure good retaining of
elasticity in despite of continuing use.
• Spider: treated cotton fibres.
• Metal parts: anti-corrosion coated back plate
designed to resist aggressive environmental
conditions.
• Basket: specially designed die cast aluminium bas-
ket to avoid disturbing resonances.
• Magnet: high Curie temperature ferrite.

Notes:
*The power capacity is determined according to AES2-1984 (r2003) standard.
Program power is defined as the transducer’s ability to handle normal music program material.
**T-S parameters are measured after an exercise period using a preconditioning power test.
The measurements are carried out with a velocity-current laser transducer and will reflect the long
term parameters (once the loudspeaker has been working for a short period of time).
