[QUOTE="Kevin McDonough, post: 212830, member: 10402"] I'm sure Peter will be along soon and elaborate, but initially during his measuring and processing of the system, he used all pass filters to flatten out the phase response of the pass bands, and delay to then line the three pass bands of the tops together properly. That was most of the work in getting the box to sound the way it does, though I'm sure, if I remember right, he also looked at adding FIR processing to further tweek and dial things in. K [/QUOTE]
