Wires, more wires ...
Bi-wiring, Tri-wiring, Quad-wiring, it all adds up to adding more wires, more cabling,
but not more ampying, amplifying, powering.
And there is nothing wrong in adding more and higher cable gauge to your system.
Loudspeakers that allow bi-wiring are simply providing more flexibility and potential sound benefits.
* As for the true real benefits of bi-wiring, simply put:
-> It can improve clarity and openness, and provide more solidity to the bass.
{As it only requires two additional speaker cables,
it is also a low cost way to achieve even better performance from your loudspeakers.}
** And as for the technical advantages of using more cables, or higher cable gauge,
and to each driver of a loudspeaker:
-> Cable resistance, cable inductance, and cable impedance ...
1. {A cable's shunt capacitive reactance, should be as high as possible.}
[Cable capacitance should be as small as possible.]
2. {A cable's series inductive reactance should be as small as possible.}
[Inductance should be as small as possible.]
3. {A cable's series resistance should also be as low as possible.}
