The wire, shorted coil turns and rapid demise of the device as an inductor. Turning up the volume, often done), may result in increased heating of the coil, melting of the insulated coating on Result in a reduction in system efficiency or loss of sound level.
#A ferrite core inductor series
The bass crossover section uses inductors wired in series with the loudspeaker driver. Inductors are not lossless devices and some energy is always lost as heat. The smaller values are used to control the tweeter frequency response. The larger values are generally used to control the lower frequencies associated with bass and mid-bass drivers, whilst Note 0.1mH is equivalent to 100uH (micro-henries). Furthermore, the whole bobbin may be constructed from ferrite, making it also a Ferrite Inductor.įor loudspeaker crossovers / audio use, most loudspeaker inductors fall withinĪn inductance range of 10mH (milli-henries) to around 0.1mH. The air cored centre may also be substituted for Ferrite core in which case it becomes aįerrite inductor. There are many combinations of these arrangements which include Nylon bobbins with a central air core making it anĪir-cored inductor. The two most widely used inductor styles use either Air-cored or Ferrite cored bobbins. Manufactured from materials which for ferrite materials have very specific electrical properties.įussy as they use air as their operating medium. Most inductors are wound on Formers or Bobbins being either circular or rectangular in shape and which are usually Its resistance, strictly impedance, at a particular frequency, well not so often in Audio work.ĭepending upon your viewpoint, Inductors are rather clever devices or just rolls of wire. In addition, two other parameters are sometimes specified (1) its DC resistance and (2) Which is measured in Henries and "is" frequency dependent. Is essentially independent of frequency, inductors have a property called inductance, (no surprise there then),

Whilst resistors have a property called resistance which is measured in Ohms and Used to control the signal level being applied to individual speaker units. Often in conjunction with other components, the property of increasing, or decreasing component impedance with frequency can be In AC circuitry the term 'resistance' is replaced by a concept called 'impedance'.

The higher the frequency, the higher their resistance. In simple terms, loudspeaker inductors can be viewed as frequency dependent resistors, i.e. Lesser extent, high end hi-if systems, use electronic crossovers which are self-powered and contain no inductors, Collectively they are generically known as passive crossovers as they are operable withoutĬrossovers used in Cinemas, Theaters, Sound reinforcement and, to a much Resistors,Ĭapacitors and Loudspeaker Inductors. These crossovers contain three main types of components, i.e.

This distributes electrical signals in a carefully prescribed manner to minimise speaker / driverĭistortion and provide a listenable result. Is an electrical circuit called a crossover. One of the key components in most of these enclosures, (where there is more than one speaker), Process electrical signals into an acceptable acoustic experience. A common link between these systems are Loudspeaker Inductors and two other component types which Most homes have a number of sound reproducing systems / items be it TV, Radio,Ĭomputers or Hi-Fi.
