[QUOTE="John_E_Janowitz, post: 5507276, member: 550657"] Just to stress again what Kyle mentioned, breakin is simply loosening up the suspension of the driver. The audio industry is filled with all kinds of voodoo about needing to run current through wire to polarize it. They sell "cable cookers" to do the same kind of stuff for interconnects. You can even buy a rock to set on your home CD player to take all the negative energy out of it and make it play cd's more happily. Unfortunately too many people buy into all this stuff and lose a lot of hard earned money for nothing. Regarding the suspension, the phenolic resin used on spiders is the main thing that will soften up slightly as the driver is moved. Ideally you want to move the driver as far as possible with as little current to the coil as possible to prevent heating the coil. That means if you're doing it free air, you want to do it at the Fs of the driver. At Fs the impedance curve is at the highest point. Since power = current x resistance, as resistance is at the highest point, current is at the lowest point. In a sealed enclosure you want to see where the Fc point is. In a vented enclosure you want to see where the lower impedance peak is. John [/QUOTE]
