[QUOTE="joetama, post: 2501739, member: 564641"] Well what causes a driver to "unload" is playing below the resonate frequency of the box, where the excursion for the sustained note at a particular power lever is greater than the driver can handle. In fact, Fs sort of works against this to almost prevent unloading from happening. Because after the Fs you have a hard drop in impedance (and this is going from High to low on the frequency chart). But usually the lowest point of excursion is at the tuning frequency, which is also usually the lowest impedance, so you can't unload at the tuning frequency. After that the impedance rises which means less power, which means less chance of "unloading" your driver. However, a poorly designed box will "unload" on it's self all the time, because of wrong tuning or too much port...... [/QUOTE]
