Passive crossover inductors. Passive crossovers are effective but not accurate requiring energy from the amplifier to function insertion loss they reduce efficiency of the speaker system and contribute distortion especially at high power. They are usually the largest and most expensive parts used and they are present in sizes and masses that have few real analogs in the electronic world except for transformers in power supplies or charging coils used in magnet chargers. In the case of inductor coils there exist a handful of ways they can generate unwanted noise.

Inductors are the biggest attention getters in the passive crossover and for good reason. Passive crossovers are usually arranged in a cauer topology to achieve a butterworth filter effect. Home car audio passive crosssovers high passlow pass capacitor coil calculator.

The term passive means that no additional power source is needed for the circuitry. Crossover networks when improperly designed andor laid out component wise are a proven significant contributor to a systems noise picture. Band pass crossovers are a combination of the previous.

L inductor mh a coil of wire. These crossover are made entirely of passive components and circuitry. Do not use these for narrow band pass filter calculations.

For higher crossover points than those shown simply move the decimal point to the right one place to match the new frequency find the capacitor and inductor values and move their decimal point one place to the left. Use these formulas to calculate for first second and third order low pass high pass and band pass filters. For this reason both of them are defined as dual elements.

Crossover points or frequencies are changed by using different values of coils and capacitors to achieve the crossover point desired. They only allow a certain band or range of frequencies to pass through and cut off frequencies above and below that band. The capacitor and inductor can be in simple or complex arrangements.

Reactive but inverse in comparison to inductors is also the behavior of capacitors. Capacitors circuit boards inductors l pads attenuators resistors and solder. Capacitors are measured in farads f the capacitance unit.
