"Linkwitz Circuit" Equalizes a Closed Box


Abstract:The Linkwitz equalizer, intended for complex-pole systems in which Q > 0.5, neutralizes the original response by
compensating the original poles with zeros, and then creates a new highpass response as specified by the designer. Like the
original, the new circuit provides a 2nd-order response.

The linearity and high power-handling capability of modern low-frequency loudspeakers have made it easy to electronically extend
the bass response. This extension is es
