*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

Is it just coincidence that the traces track characteristic impedance quite closely?Characteristic impedance always depends on inductance but taking false conclusions and writing papers on it is pretty bad. I'm sure your cables sound wonderful, but please stop this "scientific" nonsense. US spending on science, space and technology has 99.79% correlation with suicides by hanging, strangulation and suffocation. http://www.tylervigen.com/spurious-correlations |
Exactly what errors? Really. Now that just comes across as insincere attempt at deflection. I have very clearly my posts highlighted what 5+ errors - Speaker electrical model does not match impedance curve shown. - I will add that as well this is I believe, as there really is not a full standard model, an electroacoustic model, but transmission lines don’t care about mechanical effects - your model does not include parasitic capacitance or inductance in your elements and transmission lines do care about those - no scales on oscilloscope plots - your method that YOU used of measuring characteristic impedance is wrong, and at audio frequencies grossly wrong. You can’t use a transmitted square wave to measure characteristic impedance at audio frequencies - your simulation is wrong. You have not simulated characteristic impedance at all in your simulation nor transmission line effects. You would need a complex model of transmission line characteristics across audio frequencies and you must include bulk capacitance and inductance and resistance and even skin effects - you ignored skin effects though this is likely <=1db of error - Your table of wires and their characteristic values does not correlate to the graph and confuses readers. - you only showed a rough correlation to impedance not an actual mathematical correlation. Standard line, correlation does NOT equal causation - you have ignored other relevant variables, namely inductance - you called a graph the frequency response of the cable when it is clearly not. It is the cable voltage drop versus frequency which is lot the same thing - you don’t explain or correct for the 2db measurement drop at high frequencies which without knowing why puts unbounded error on the measurements at high frequencies - the scale of the spectrum graph is not listed, only db and this is a near meaningless term without the required scale. - the settings for the spectrum analyzer are not listed so we don’t know if it is average, RMS average, peak, etc I could go on but what would be the point. You fail to acknowledge the obvious and substantial flaws. |
We are doing a Zoom session 6 PM GMT 5 Dec, and we will show you the test with the same cables. Great so you are going to do a zoom call that shows that lower inductance cables have less voltage drop than higher inductance cables, something almost no on disputes and you are going to claim it is because of transmission line effects. |
Townshend-audio, It appears that you joined our audio forum only in attempt to place free advertisement for your product. It is dishonest IMO and I wouldn't buy anything from you. Audio2design attempted to explain to you why using square waves in audio is nonsense, but you don't get it. Administrator please remove townshend-audio posting. We don't want it here. You want to advertise? - pay like everybody else. |
