When we listen to live music, all of the highs & lows reach our ears in the same relationship to each as when they were created by the instruments. If the same live music were to be recorded and played back through a loudspeaker system, the loudspeaker would introduce frequency dependent phase shifting. The inductance of the speaker's voice coil creates a stronger impedance as the signal's frequency increases, resulting in a time delay. Consequently, frequency components with large negative phase shifts (high frequencies) arrive at the listener's ear later than signals undergoing small phase shifts (low frequencies). The resultant signal is distorted in the time domain to the listener's ear. Audio material containing sharp transients (e.g. percussive and plucked sounds) suffers the most from this phenomenon, making it seem unfocused or mushy.
In order to address these problems inherent to basic loudspeaker design, BBE Sound, Inc. has developed a circuit that has two primary functions. The first adjusts the phase relationships of the low, mid and high frequencies. Since a loudspeaker's natural tendency is the add progressively longer delay times to higher frequencies, BBE sound technology adds progressively longer delay times to the lower frequencies. This creates a kind of "mirror" curve to the time delay curve created by the speaker, neutralizing its phase distortion.
The second major element in BBE's sound technology is the augmentation of the higher and lower frequencies. Loudspeakers tend to be less efficient in their extreme treble and bass range. Most sound-reproducing systems include a circuit for boosting highs and lows, showing an accepted awareness of the loudspeaker's efficiency problem. The BBE system, however, provides dynamic, program-drives augmentation which combines with the phase compensation feature to restore the brilliance and clarity of the original live sound. The result is, as one professional journal phrased it," The most hearable advance in audio technology since high fidelity itself."
