[QUOTE="ciaonzo, post: 8073445, member: 607015"] There's good reason for that, especially for anyone still using the passive crossover that was supplied with the components. Back in the day there wasn't much T/A so the best way to equalize path-lengths was to mount drivers in the kicks. Aside from that, it's crucial to keep the mid and tweet as close together as possible to preserve phase coherency and a good/even power response. Splitting the mids and tweets apart by more than a full wavelength at the set crossover frequency introduces phase anomalies and comb filtering issues. People tend to think that you can solve this by simply inverting the polarity on the tweets, but that throws the design of the partnership between the components and the passive crossover right out the window as the polarity was already taken into consideration based on the slopes involved. With T/A and steep filters, splitting drivers is not as big of an issue but there's still penalties involved when compared to setups acting more like a point source, coax and full range. [/QUOTE]
