[QUOTE="Norval, post: 89523, member: 62"] I don't even like the idea of two mids, now 2 tweeters are even worse. Think of it this way, at 3400 Hz the wavelength is only 100mm. If the path difference between the tweeters and your ears differ with 50mm, you'll get complete cancellation at that frequency. If the path difference is 25mm, you'll get phase distortion at that frequency, resulting in a mudded sound. And so the list continuous. Now why do they build centre channels with two mids? 1) It works well if the x-over frequency is very low. But take note, there has to be just one tweeter. 2) It looks nice. High End designs will use either one mid and one tweet, or two mids at low x-over frequency. But hey, that's just my humble opinion ;) [/QUOTE]
