*WHITE PAPER* The Sound of Music - How & Why the Speaker Cable Matters


G'DAY

I’ve spent a sizeable amount of the last year putting together this white paper: The Sound of Music and Error in Your Speaker Cables

Yes, I’ve done it for all the naysayers but mainly for all the cable advocates that know how you connect your separates determines the level of accuracy you can part from your system.

I’ve often theorized what is happening but now, here is some proof of what we are indeed hearing in speaker cables caused by the mismatch between the characteristic impedance of the speaker cable and the loudspeaker impedance.

I’ve included the circuit so you can build and test this out for yourselves.


Let the fun begin

When discussing or simulating characteristic impedance and transmission lines:One must be careful not to use the short form formula for ’Radio Frequency Characteristic Impedance’ which is only valid for frequencies near one megahertz and higher.Below 1 MHz down to low audio frequencies you need to use the long form complete formula.The four important parameters (which should be measured at the frequency in question) are:
[G] Conductance ( siemens ) (was mho)
[R] AC resistance [L] Inductance
[C] Capacitance

at radio frequencies the [L] & [C] values are large so the [R] & [G] values are not important.
at audio frequencies the [L] & [C] values are small so they are not important. It’s the [R] & [G] values that are important.
Here we are, December 3, and no details have "followed" about the December 5 zoom call. When has a vendor given less than 2 days notice of a presentation? That is just odd .....
