A summation is configured to combine an inverse of the source signal with an output of the equalizer. An amplifier is configured to receive an output of the summation, and a speaker is coupled to receive an output of the amplifier. According to an embodiment, the equalizer comprises an adjustable equalizer. According to another embodiment, a digital signal processor implements the equalizer and summation. According to yet another embodiment, in absence of the filter, a combination of the speaker and electronic components coupled with the speaker have a larger amount of phase at low frequencies and a smaller amount of phase at high frequencies.
