[QUOTE="Frank Koenig, post: 65099, member: 416"] Re: Visualizing the Mag & Phase of the 2 Element "End-Fire" Sub Array Just to be clear, I was not suggesting the use of electrical FIR filters to process signals for subwoofer arrays. I was only acknowledging that some of the math is the same. The output of an FIR filter is the weighted sum of variously delayed copies of the input signal, just as the sound at a point in space is the weighted sum of variously delayed versions of the sounds coming from the sources. So the same mathematical approach (z-transforms) can be used for both. --Frank [/QUOTE]
