摘要： An electronic circuit for dynamically adjusting the spectral content of an audio signal. The circuit includes a constant current source, a output buffer amplifier and a biased inductor for introducing controlled amplitude asymmetry. This apparatus thus can be arranged to process an audio signal so as to introduce a predictable and controllable harmonic distortion that is negligible at small signal amplitudes and increases progressively at larger signal amplitudes.

摘要： A method of optimizing the low frequency audio response emanating from a pair of low frequency transducers housed within a cabinet. The low frequency transducers are electrically connected to a power amplifier and source of audio content. The resonant frequency (Fs) and amplitude (Q) are characterized as to the high-pass pole of the low frequency transducers as they are mounted within the cabinet. An equalizer is placed between the amplifier and source of audio content for canceling the complex pole of the low frequency transducers and for establishing a new complex pole as a cut off point in which no low frequency sound would be generated by the low frequency transducers.
