Inductor One of the next things you need to consider when buying car audio crossovers is the inductor. This will only apply when buy passive designs. Passive crossovers can be made with air core or iron core inductor. It's usually best to buy passive car audio crossovers that have air core conductors. They are less susceptible to damage and distortion, but they have higher resistance. Slope You will also have to think about the slope when buying car audio crossovers. Slope refers to the rate at which the crossover attenuates, or cuts, the signals. It is measured in decibels per octave. Most car audio crossovers have a slope of 12 dB per octave. Some will have a slope of 24 dB per octave, which is useful if you have subwoofers. One of the next things you need to consider when buying car audio crossovers is adjustment. You should look for a design that is continuously variable. Many car audio crossovers have a set of frequencies that they can work with. Designs that are continuously variable can be adjusted to work with a range of frequencies. - Kirsch Loud Speakers -
