Now, if you put any resistance between the amplifiers output and the speaker, that resistance will degrade the damping effect of the amplifier. This undesirable resistance acts to sort of “decouple” the speaker from the amplifier. This is why we try to use large gauge/high quality speaker wire in our high-end systems. Larger gauge wire has less resistance.
There is a common misconception that loudspeaker cable must be large in diameter and have a low DC resistance in order to provide good bass response. DC resistance is relatively unimportant. What really matters is the characteristic impedance (AC resistance) of the cable. Music is an AC signal after all. Most of these large diameter/low DC resistance cables have excessively high characteristic impedance anywhere from 100 to 600 ohms with some measuring in the 1000’s of ohms. The Au24 Loudspeaker Cable is only 4mm or 1/8" in diameter. Although the DC resistance may be slightly higher than the garden hose variety speaker cables the characteristic impedance is only 16 ohms. Musical signals from the bass to the overtones pass through this cable with less actual impedance than a cable with a lower DC resistance. The Au24 Loudspeaker Cable provides nearly perfect bass timbre and extension. Plus, the low eddy-current resistance means the cable is very quick and linear in the time domain. Voices and instruments sound strikingly real with this loudspeaker cable.
Second, time and phase alignment is a long-term satisfaction goal that doesn't sell like the sizzle of titanium or berylium drivers, and hyper-detailed and initially exciting speakers. In my opinion, one of the reasons audiophiles buy and try so many speakers is that they are looking unconsiously for the wholistic presentation that phase and time alignment can help provide in the context of a special system. The big flashy speakers provide short-term fun, but long-term disatisfaction....

Great explanations! However, I have never understood one thing. Why can't crossovers be implemented digitally? Crossover order is not an issue, neither is compensation for the group delay through a digital delay line. The only downside that I see is the need for one amplifier per driver, but that is not worse than bi-amping in a two way system.
