[QUOTE="Andy Turner, post: 204154, member: 10677"] Peter Van Gils, I've been working (hard) to get this project to sound good, but with no luck so far. My measurements keep showing a drop in the 4-6khz range so I thought I would try inverting the VHF as you did. I am using the passive filter(16/16) from BMS. I tried but as can be seen in the measurement below, it doesn't work for me. Any idea what is going on? The measurements are indoor on a sub 1.53m from floor and mic at 60cm distance pointing directly into HF950 horn. 10ms window and 1/12 smoothing. Inverted in red: [ATTACH=JSON]204155.vB5-nodeid=204155[/ATTACH] Phase: [ATTACH=JSON]204156.vB5-nodeid=204156[/ATTACH] [/QUOTE]
