[QUOTE="winkychevelle, post: 8874045, member: 611804"] Time alignment is used to delay every speaker closer than the furthest to have the sound hit the listeners ears at exactly the right time. If this is true the image should be about eye level centered with your head. Height of stage is often limited by speaker locations but it's less important to me that centering left and right. Keep in mind not all music is recorded with a center some music the sound stage wanders left and right. Time alignment can be close to perfect and you still have phase off a bit. But phase can't be easily adjusted with every dsp only some have the ability to unwrap it or at the very least use allpass filters for severe nulls. But getting the phase between the subs and the midbass is the single most important thing for upfront bass. Or that kick in your chest feel. Some people get lucky with install locations but a dsp can fix a lot of that these days. Eq helps a lot when you can do each individual drivers since it lets you smooth out the frequency response but excessive eq can cause issues as well but to a lesser extent. Personally if you aren't running full active I wouldn't consider a dsp beyond the one built into most radios [/QUOTE]
