"Cable reflection can be ignored at audio frequencies (very low) and at these short lengths. The wavelengths are so long compared to the physical dimensions that reflections can be considered instantaneous at both ends and do not alter the electrical signal delivered or the output of the amplifier in any way.
Reflection and consequently impedance matching becomes important for high frequencies like your cable TV or over great distances like power transmission lines."
Hmmmmm.... So, you're saying we can ignore RFI/EMI too because those frequencies are not in the audio frequency range? Lol Methinks you're confusing electromagnetic waves with acoustic waves.
