[QUOTE="Ti Liptak, post: 211775, member: 11813"] Thanks Mark! 4096 taps @ 48khz. I've watched some videos on the "phase trace overlay method". Went ahead and downloaded a trial of Smaart and can use the Q-sys as a USB soundcard. I've gotten that working, but haven't run measurements yet. Hopefully this evening. With the mid hi's, Peter kindly sent over his latest FIR settings and I directly copied them from the Lake Controller. His approach of using FIR linear-phase filters for all the crossovers except the sub make sense to me. I will try to replicate that. I'll post some measurements shortly and perhaps you can steer me in the right direction. ----- As a promise to this thread, I'll also post some additional drawings of the mid-hi. Max get's most of the credit, since I will use his as a baseline, but with some modifications now that I've actually built two pairs. Will do two versions, one for people building without a CNC with exact measurements of each part of the horn path so you can easily trace it out + part dimensions + cutsheets. Then a second version for CNC users that you should be able to directly import into your CAM tool and define your toolpaths. Will color code it so it's super easy, EG: Red paths = outside throughcut ---- Green paths = 6mm deep pocket etc. [/QUOTE]
