[QUOTE="Andy Turner, post: 204113, member: 10677"] I get it that you minimize the reflections by measuring ground plane but I'm not understanding what these measurements can be used for? At low frequencies I get weird response partially due to the D'appolito arrangement? The High frequency is off- axis and also suffer from timing issues at XO ? I am bit lost here. Need to study more :0) Enclosed measurement of speaker standing on the ground and mike 1 meter distance on the ground. (IR window 10ms and 1/24 smoothing. XO at 700/48db LP 100/24. [ATTACH=JSON]204114.vB5-nodeid=204114[/ATTACH] Is this the best baseline for adding PEQ and so? I made PEQ's based on measurments made with the speaker laying flat on the back and mike 1m above, and was able to make it relatively flat (+12 db), - but the sound was really no good for me :0/.
