Generally, an enclosure system comprises anumber of loudspeakers
configurated eletricallyand acustically, in order they can
reproduce the full spectrum of audio frequencies.
For the proper matching between the loudspeakers it is utterly
important to know their frequency response.
Good loudspeakers specifications includ a graph of the frequency
reponse. The graph shows the maximum deviations form a perfectly
flat response, and where the deviations occur.
Many loudspeakers manufacturers measure the frequency response
in a room without echoes, as known as an anechoic chamber.
In spite of so many improvement in the electroacustical measurement
techniques, the interpretation of the frequency response specifications
often is difficult due the number of variable involved.
Over the year the acustical engineers were devoted to create
types of loudspeakers which could be able to reproduce as
much as possible the full range of the audio frequency spectrum.
Such continuous search for the ideal loudspeaker led to the
birth of specific type of loudpeakers as kwown as frequency
transducers for reproducing low, mid and high.
