time alignment wiring

i was wondering if anyone has a wiring diagram for time align speakers. i saw a schematic for it once but i cant remember where. the head unit im going to buy has the function built into it, its the jvc kdr9 series or something like that, wish i could afford the stage 4 from pioneer though. any help will be great. thanks35 Hertz custom car audio and automotive fabrication

I do not know of any way you could wire a speaker and delay the signal.  Well no practical way. 

Its for positioning the focus on the drivers seat of a vehicle. The article that read if I remember correctly was talking about how phase or cycle shifts by so many degrees after passing through a load. It also said that you have to do this with a two channel amp and it won't work with a 4ch. Its a way of wiring the mid/high and it may not be an actually delay but more of a shift in the soundwave Which causes the signal from each speaker to hit the same point at the same time.35 Hertz custom car audio and automotive fabrication

This is a new one on me... The MOST you can effectively shift any analog wave is 360 degrees, and then you are back in phase. The most you can DELAY any analog wave is infinite. See the disparity here? Phase Shift vs. Time Delay is like asking the San Diego Chargers to play the LA Dogers in a game of basketball. They're all very different things and are achieved COMPLETELY differently. Speaking from experience, the TD is a really nice thing to have, but I know of no way to do it passively, other than tens of thousands of feet of wire. Yes. PER SPEAKER! Through any inductor or capacitor there will be a phase shift, this is true, but there won't ever be any time delay worth mentioning. On the order of picoseconds (or even smaller timeframes). TD is really only practical in a digital processor. All that being said, I can't also see ANY reason that if a two-channel amplifier WOULD work, that a four-channel amplifier would NOT work. A four-channel amp is just two two-channel amps in one chassis... Nothing else. Using any circuit with inductors and capacitors (like a crossover) can certainly (and absolutely DOES) shift phase, but it also bandwidth limits the frequency response. It's most certainly not the same thing.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Passive time alignment can be accomplished through driver positioning, but that is not really practical in a vehicle.  As theVolt said, DSP is likely your best choice.Support the12volt.com
