ABSTRACT:
A system and method for achieving extended low-frequency response and increased low-frequency sound pressure output capability in a loudspeaker system is provided. The system and method comprise mounting a low-frequency driver in a ported box, tuning the ported box to a sufficiently low frequency so as to result in a frequency response that can be modeled substantially as a second-order response, and equalizing the response of said driver-box combination with a second-order biquadratic filter function to achieve the desired frequency response characteristic.
