The voice coils feature high quality, American-made wire and adhesives increasing the thermal working range of the coil. Additionally, thicker, black-anodized aluminum formers increase thermal transfer from the coil wire. The HDX line makes it easier to tune low-frequency pressure into a system without sacrificing impact.

Apr 15, 2012· aluminum has far greater power handling. that's why it's used. lot of massive,expensive subwoofers uses dual to quad aluminum voice coils with a special alloy coating to prevent oxidation. sometimes it uses OFC coating on some speakers but i never seen much do so. aluminum also dissipates heat much faster so you can drive more power for longer times without the risk of melting or burning the voice coil. aluminum

A voice coil (consisting of a former, collar, and winding) is the coil of wire attached to the apex of a loudspeaker cone. It provides the motive force to the cone by the reaction of a magnetic field to the current passing through it. The term is also used for voice coil linear motors, such as those used to move the heads inside hard disk drives, which produce a larger force and move a longer

actually - and I don't know why - brass was often used in the old days for voice coils in woofers and extended range drivers. Aluminum was also common, probably because on a per dollar as well as on a a per gram of mass basis, its conductivity is very high. Copper's a good default, though.

Jun 09, 2013· Aluminum requires more cross section area to do the same job. Aluminum has lower mass than copper giving the ability to move the same current, albeit through a larger conductor than copper, but with an overall reduction in mass. The larger surface area of aluminum can have an advantage in a voice coil when it comes to the length of the coil

Mar 08, 2009· Copper doesn't last longer. The main difference is you will have a longer winding on the coil with aluminum than copper to acheive the same thermal potential. Copper will give a little stronger BL (motor strength) and is a better conductor of electricity. BUT aluminum weighs 1/2 of what copper does and handles heat better.

Anodized Aluminum Voice Coil Former. Rockford Fosgate subwoofers use anodized aluminum voice coil formers that provide superior heat dissipation (up to 100° at full power levels). Unlike traditional plastic substitutions, aluminum acts like a heat-sink to quickly dissipate thermal build-up on the voice coil.

The need to increase the thickness of aluminum wire is a consideration in its use in tight voice coil gaps—especially as it expands more than copper voice coils when hot. So, this wonder wire is lighter than copper, has a current-carrying capacity several orders of magnitude higher than copper, and behaves more linearly at high power.
