I am glad to see my comments sparkled such a discussion. Hopefully some folks will now have a desire to learn more about acoustics.
I was educated and worked in the field for 40+ years.
I was building my own amplifiers and speakers (building one right now), and performed various sonar and antenna calculations.
I would not dare to discuss a topic I do not fully understand.
@mgrif104 All said above about role playing factors, is true. I can add to the list:
- temperature factor
- wire attachment and placement (affects oscillation)
But all those factors are quite negligible in our application. Because of two factors, mainly - amplitude and frequency range of an audio signal.
We can compare with impact of a wire resistance (it actually plays much bigger role). Does it really makes a notable difference if your wire gauge is 10 or 12? The resistance of 10 ft copper piece is 0.012 and 0.015 ohms, respectfully. Compare with a speaker nominal impedance of 4-8 ohms.
Other factors mentioned play much, much lesser role.
Think of why audio or power cables do not have any shielding (speaking of antennas).
As an experiment, connect oscilloscope and/or spectrum analyzer to you speaker terminals. (It is quite entertaining, actually). Record same audio signal using different wires. Compare. I bet you will see no difference.
Oh, by the way, what about headphone wires? the wires inside of a speaker box?
Good luck, with all due respect.
