[QUOTE="Babs, post: 3059991, member: 567066"] To give you an example.. Phase between multiple drivers is the reason that your typical two way home speakers are precisely designed so that the sound from both the tweet' and the woof' hits your ear at the same time.. They're vertically aligned to be both the same distance away.. Impossible in the typical car. Also, in the "sweet spot"... You're the same distance from the Left and Right channels.. So a snare hit panned in center is one precise "pop" rather than a blurred pop from left then right. If you've ever studied how waves work you can see when you combine same-frequency waves in perfect phase, they amplify to a perfect wave of the same frequency but higher amplitude (volume). If the waves are out of perfect phase, then the resulting wave is distorted and the amplitude at that frequency then is also adversely affected... So, what's that mean... At the frequencies where your tweets and mids crossover, phasing is important... At that point I guess you could say improper phasing can be called "crossover" distortion. But also, with significant differences in distance, the closer driver will be sending sound to your ear sooner than the other driver, so it will significantly blur the sound image and wreck your sound-staging. In layman's terms.. Just plain sounds better when the speakers are physically or digitally aligned (by delaying the closer speakers to compensate for improper placement in a car) so the signal from each hits your ears at the same time.
