[QUOTE="Fast1one, post: 4283359, member: 567387"] Of course not, but when compared to the effect of level matching its fairly insignificant because the cabin is a relatively tiny space... If you can get the SPL levels of the left and right midranges equal to your left and right years respectively, you will get fairly SOLID center imaging, so long as you take care of early reflections (I.E. Foam products)... Thats the thing, you simply can't make assumptions about absolute phase until you have the speakers mounted in the position you want and you start testing...a full 180 degree phase shift may be too much, in which case T/A (a very LITTLE amount) can be used (usually passenger side works best)... You CAN have a great sounding system without T/A though. Which is what I am getting at. Level matching with midranges is much more significant than applying T/A. In addition, playing with relative phase of the speakers is a rudimentary way of applying time alignment... For now, just go active with a simple crossover, because once you get sucked in you will spend HOURS trying to get concrete imaging while maintaining tonality...not to mention it will dent your wallet [IMG]//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif[/IMG] [/QUOTE]
