re: #73 A Cranky One
Here is a typical voice coil for a woofer.
All the power from the amp goes through these tiny wires inside the speaker.
So do we need wires as thick as my thumb to connect to these tiny wires? Ridiculous.
Now a good cable should have low inductance and capacitance to avoid altering the signal. And low resistance to prevent signal loss. Beyond that, no magic is required.
