[QUOTE="dirthog, post: 5390369, member: 572229"] Do you use it? Yes Do you care for it? Absolute necessity Any things to be done before the T/A process? T/A should be the first thing What are you trying to achieve (goals) with T/A? Center the sound stage and reduce phase cancellation _________ What's your method(s)? T/A should be the first thing you set. The reason is because it changes phase relation between a set of coaxial or between the mids and tweeters in a component configuration. If you EQ first and get everything to sound it's best and then change T/A it will affect your EQ because the phase relationship will change. But it you T/A first the EQ will not effect your phase relationship but just the frequency levels of what you're adjusting. Here's how I tune. I measure and adjust T/A to get a good starting point. I then adjust T/A using my ears and pink noise to get a strong and focused image hopefully in the middle of the dash. At this point it might not be exactly in the middle of you dash but should be close. It's more important to have a strong focused image at this point. Once you feel you have accomplished that level match the drivers until the image is in the center of your dash. Let's say you have a strong and focused image but it's left of center. Your next step would be to lower the left side level/gain and raise the right side level/gain the same amount until it's centered. The third thing I like to do, if you have individual left and right EQ, is adjust each frequency to get better focus. With the pink noise we have created the best center image we can but there still might be some frequencies that wave left or right of center. Burn a cd with the frequencies that are adjustable with your deck. Play each one and again adjust the left and right EQ so that each frequency comes from the center of your dash. Now it's time to adjust you EQ to your liking. [/QUOTE]
