I'm not here to start a cable war. Assume for this discussion that cables do matter, would changing the internal wiring somehow affect what the designer acheived in the first place, or is it as simple as swapping speaker cables? I'm not an EE and I don't know if changing the resistance or impedance by using diff wires can ill-affect the crossover's function. Some manufacturers use Cardas internally. Why don't we hear more about this as a tweak? My guess is that even if it works, it's risky to do because 1. not everyone is the DIY type 2. finding someone trustworthy to do it 3. what if it doesn't sound good, reversible but more involved 4. messing around with the contacts on the drivers and X-over by soldering over and over again might cause permanent damage, which is why #2 is important.
