According to the BBE docs, speakers tend to add more delay to higher frequencies, so by delaying the low frequencies in the source, the listener hears lows and highs at the same time. The BBE docs aren't exactly clear on how the higher impedance at higher frequencies coresponds to a phase shift(I'd think it would just decrease the amplitude) but I'm hoping some of the crossover design papers, or my electronics textbook, will have some more enlightening info. -spencer
