The scale of the audio spectrum to be reproduced imposes unavoidable physical constraints. T o appreciate this, you only need to consider the wavelengths to be produced. The wavelength is expressed by: λ = v/f v is the speed of sound in air (340m/s) f is the frequency of the signal to be r eproduced Therefore at 100Hz the wavelength λ = 3.4m At 1 ...

The role of the Crosso ver The crossover has the function of distributing the signal fr om the amplifier to the various drive units in a loudspeaker: bass, midrange and treble. The most critical area of filtering this signal, with out any doubt, is between the midrange and treble. A low-pass filte r rolls off the higher fr equencies of the midrange ...
