Under the power ratings you talk about reactive loads. Specifically, this statement has me puzzled, "Depending upon the input signal frequency, speaker loads may be resistive or resistive with an inductive or capacitive component." Since is speaker is essentially nothing more than a coil of wire electrically, how does this manifest itself as a capacitive element? Sure the winding may have some capacitive properties of negligible value, but wouldn't the inductive characteristics overshadow any capacitive ones? |

The crossover network has a big efect as well, if you're using passives. I have home speakers that present a 4 ohm, flat resistive load from 20-20KHz for example. anyway that article was originally written regarding home audio and was adapted for mobile application afterward. Some elements are still present relating more to home settings, and speakers that are full range cabinets.. not individual component drivers as we deal with in the car audio world more often. |
