What Does An Inductor Do In A Crossover

When using more than one inductor in a crossover the electro magnetic fields of the inductors can interfere with each other causing an unpleasant result. Using an inductor aka.

Ideally the inductor should have very low dc.

What does an inductor do in a crossover. A coil or choke in series with a speaker will block higher frequencies while having little effect on the lower bass frequencies. Band pass crossovers are a combination of the previous. Inductors are the biggest attention getters in the passive crossover and for good reason.

Capacitors are used in high pass crossovers because they cut out the low frequencies. The inductor is a wire shaped so that the magnetic field will be much stronger. The have a constant resistance to the flow of electrons which does not vary with the frequency of the signal.

Shop brands like dayton audio erse audio jantzen audio and more. 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. They only allow a certain band or range of frequencies to pass through and cut off frequencies above and below that band.

Impedance is a measure of how much the resistor capacitor or inductor impedes the flow of electrons at any given frequency. The reason an inductor works the way it does is because of this magnetic field. Aging of capacitors within crossover networks hi folks i have red that capacitors within loudspeakers crossover networks show aging with regard to their characteristics inductance capacitance reactance etc which has consequences for the crossover itself and finally also for the loudspeakers sound.

Inductors used in passive crossovers. Also keep the fields out of phase with each other by rotating the inductors 90 degrees. An inductor has a property known as inductive reactance effectively what this means is that the resistance of the coil of wire increases the higher the frequency goes so it rolls off the treble because its in series with the bassmid.

A current through any wire will create a magnetic field. Shop crossover inductors in air core copper foil and solid core styles at parts express. These are normally installed inside the speaker cabinet both use capacitors and inductors to form crossover filters and control the sound sent to tweeters midrange speakers or woofers for best audio sound quality.

This field does some magic physics stuff that resists alternating currents. That is why it is best to keep the inductors as far apart as possible. Crossover points or frequencies are changed by using different values of coils and capacitors to achieve the crossover point desired.

Resistors are the simplest components and the easiest to understand.
