• Voice coil: edgewound aluminium wire with high
temperature bonding strength. Polyimide fiber glass
former able to withstand high temperatures.
• Cone: light and stiff paper cone to provide good mid-
frequency response.
• Surround: plasticized cloth.
• Spider: cotton spider.
• Metal parts: effective protection against corrosion.
• 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).
