Almost any piece of copper (or silver) wire works as a good conductor from DC up to around 1GHz. That is an infinite range of frequency decades, but doesn't take account of the age of the wire. Let us assume that after manufacture the wire will be used for about 20 years before being replaced. That is about 631ks; a lower frequency of 1.6nHz. So wire works over 18 decades of frequency. I think we can call that 'full range'.Kleen Air said:About full range cable I could reply : what is a full range speaker ?
All speaker coils are a compromise between weight (actually, mass) and power handling. This has almost nothing whatsoever to do with cables, where weight is not really an issue at all and power handling is far easier than a voice coil.I could also asking : why the awg inside a tweeter moving coil is different than inside a woofer ? is it only cause weight or is it also cause power (voltage x current) handling increased for low frequencies ?
