AB  - The length of the impulse response of a typical piston driver is largely determined by the characteristic second-order high-pass response of the driver. This time response makes anechoic (i.e. gated) measurement difficult in non-anechoic environments, as reflections must be suppressed to returns of 30 ms. or longer. This paper outlines a quasi-anechoic frequency and phase response modification technique using a tuned notch, or band-cut, equalization that shortens the impulse response and allows correct full-range speaker measurement in moderately sized non-anechoic rooms.
