Assume they are within 1/4-wavelength (of course another question, what part of the operating bandwidth do you choose and why?) While correct in basic concept, it's misleading in practice.Īs an example, place 2 speakers in a center cluster side by side. It has been a very long time so some of the above may be worth looking into more and it is a very "General" simple go through. Check with your speaker manufacture as they may have the correct delay time listed. Most direct loaded (nonhorn loaded) sub mids I have measured the mid was ahead of the sub. If your crossover freq is 100hz put on a 100hz test tone- Of course this would be if your mid was indeed ahead of the sub.

The cheep, quick way is to put on a test tone at your crossover freq and add delay until it gets the loudest.

I don't know what you have for subs but most subs are behind the lowmid driver so you would add delay to you lowmid. I use outside of cone to outside of cone. If your sub and midrange are closer than 2.82 feet then it would be worth your while to have them put in alignment. To find the size of a wave divide the speed of sound by the freq. This is the phase relationship of the drivers. Of course they could be anywhere in between. Now if I added 5ms delay to the first speaker now both speakers are moving in and out at the same time increasing the spl at the crossover point.

Again this is at the crossover freq if the two drivers are closer than 1/4 of their wave length apart. A BIG drop in spl at the crossover point. Knowing at 5ms the first speaker has just started to move in and the next speaker has just started to move out the postitive pressure and the neg pressure cancel each other out.

2.5ms to reach full in and 2.5 ms to reach rest state again. 2.5 ms to reach "rest state" or the state it was before it started to move. If one speaker starts moving and 5 ms later then next one does what happens? Knowing this we can see how delay is used to put two speakers in phase. So it takes 10ms for a cone to move in and out once when it is repoducing 100hz. To find out how long it takes to do this divide the freq by 1000. "100 hz" as an example is the speaker moving in and out 100 times in a second.

If the first speaker moves full in and out once before the other speaker does the second speaker is in phase but one cycle off. Think of the full postive to full neg as one wave or 360 degrees of a circle. When two speakers are reproducing the same freq wave how they are in relation to each other is phase. Full positive pressure when the cone is full out. When a speaker moves in and out once it makes one wave. When they are more than 1/4 wave length then you can use delay to get your desired freq better in a target area in the room. When 2 drivers are closer than 1/4 wave length they act as one driver so keeping them in phase alignment is important through out the room. I have seen some suggestions that you could use an SPL meter, if you don't have an RTA, to get the system closer, what would be a way to do this if you only have an SPL meter, thanks for any input on this, as always just trying to learn more from the help of this forum, thanks If this is something that should/could be done how would the best way be to do this.
