Frequency Delay Dispersion

The phase nonlinearity of most second- and higher-order speaker crossovers is illustrated with the step response of cascaded all-pass networks. Audibility issues are discussed. The audibility threshold depends on many factors; reports vary from about 100μS to 2mS. A sufficient amount, though, is certainly audible.

Correcting Driver Phase with Digital All-Pass Networks

This article shows that in the digital domain, you can implement phase corrections in a very straightforward way, although there is still an approximation involved. My focus here is on compensating for phase nonlinearities in the driver. This article illustrates the problem for the midrange driver in a three-way system, which will be crossed over to a woofer on the low end and a tweeter on the high-end. This article was originally published in audioXpress, January 2011.

The controversy over subjective versus objective loudspeaker evaluation has raged on for decades. However, to my mind, there is no controversy. These criteria are simply two faces of the same coin. In over 30 years of designing loudspeakers, I have found the following measurements taken as a group provide the strongest predictor of loudspeaker preference available to us today.
