Satisfactory output of the complete system comprising the audio crossover and the loudspeaker drivers in their enclosure(s) is the design goal. Such a goal is often achieved using non-ideal, asymmetric crossover filter characteristics. [5] Many different crossover types are used in audio, but they generally belong to one of the following classes.
Capacitors and inductors are applied together in tuned circuits to select information in particular frequency bands. For example, radio receivers rely on variable capacitors to tune the station frequency. Speakers use passive analog crossovers, and analog equalizers use capacitors to select different audio bands.
Loudspeaker time-alignment, usually simply referred to as "time-alignment" or "Time-Align", is a term applied in loudspeaker systems which use multiple drivers (like woofer, mid-range and tweeter) to cover a wide audio range. It involves delaying the sound emanating from one or more drivers (greater than 2-way) to correct the transient response ...
Nearly all crossovers are passive circuits, designed to match the characteristics of the drivers and their mounting, and are built of capacitors, inductors, and resistors. Active or 'electronic' crossovers are used in some high performance hi-fi speakers, and in professional sound reinforcement systems .
Speakers use passive analog crossovers, and analog equalizers use capacitors to select different audio bands. The resonant frequency f of a tuned circuit is a function of the inductance ( L ) and capacitance ( C ) in series, and is given by: f = 1 2 π L C {\displaystyle f={\frac {1}{2\pi {\sqrt {LC}}}}} where L is in henries and C is in farads.
The speaker coil inductance of a loudspeaker generates a rising impedance, which is worsened by the output inductor generally found in analog power amplifiers; the cell is used to limit this impedance. [2] The documentation for some power operation amplifiers suggests the use of a "Boucherot cell between outputs and ground or across the load". [3]
A loudspeaker (commonly referred to as a speaker or, more fully, a speaker system) is a combination of one or more speaker drivers, an enclosure, and electrical connections (possibly including a crossover network). The speaker driver is an electroacoustic transducer [1]: 597 that converts an electrical audio signal into a corresponding sound. [2]
A single capacitor sufficed as the crossover 'network' for the B-300. The system could be expanded to a 3-way B-302A by adding a midrange and full 3-way Bozak crossover. Acoustic suspension arrived in the loudspeaker marketplace in 1955, making it possible to get low bass from a small, bookshelf-sized enclosure.
