Posted September 6, 200520 yr OK tell me if this looks correct.TD=time delayA=distance in feet from ear1132ft/sec=speed of sound1000=msTD=(A/1132)*1000Left=2.2ft1.94ms=(2.2/1132)1000Right=4.6ft4.06ms=(4.6/1132)10004.06-1.94=2.12 TDDoes this look correct? I found this formula on ECA, I am having problems finding other formulas on the topic.
September 6, 200520 yr There's some type of formula in my Alpine 9835 Manual...but I'm at work and I can't view the damn downloadable manual. But it seems right from what I can remember...NG
September 7, 200520 yr Author Found the mesurments in the eclipse manual. Manual...A=TDB=furthest speakerC=speaker to adjustFormulaA=(B-C)/34My case1.5ms=(172.7-121.9)/34
September 7, 200520 yr In pioneer H/U's you just measure the distance and put it that measurement into the H/UIs it different than what alpine/eclipse do ?
September 7, 200520 yr Author In pioneer H/U's you just measure the distance and put it that measurement into the H/UIs it different than what alpine/eclipse do ?<{POST_SNAPBACK}>yes, eclipse you have the millisecond delay and the DB level adjustment for the left and right channels for highs, mids, and lows.
September 7, 200520 yr Author Good ol pro mode.Pioneer uses the distance for pro mode as well<{POST_SNAPBACK}>eclipse has preset for normal mode. Ex. left seat, front, right seat, rear.pro mode is broke down like my previous post.
September 7, 200520 yr Pioneer you choose the seating position.say left seat frontthen you measure each speaker for the left front same goes with the right.You cant do the custom t/a with all seats or both front seats selected. Just the preset onesIts a bit better than what eclipse offers for normal mode.Thats only in the higher end units. The regular one is just like what eclipse offers.
