*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

Why would you want 100KHz flat response. You can't hear it, your speakers cannot recreate, and if they could they would likely distort and modulate distortion to audible frequencies.  100KHz amps are mainly to ensure no phase shift in the audio band (and for marketing).

12 awg stranded only drops in resistance about 50% at 100KHz.  You could just use 2- 12 awg stranded, maybe even 1 - 8awg stranded.  18 - 24 AWG would be just as good at 100Khz as 108-32awg and a lot less work.

w.r.t. a liquid conductor, as long as it has inductance, capacitance and resistance (it will), then it will have a characteristic impedance.  However, the only problem to solve is inductance and that would be hard to interleave (for speaker cables).

Technically there are always reflections, however, the impact on power transfer at audio frequencies is several hundred db down.

Is it just me, or do these Townshend cables seem to be quite similar in design to the Goertz Alpha-Core's?:

Get a foil inductor, preferably 12awg, and double sided sticky tape. One inductor builds a lot of speaker cable similar to the Goertz or Townshend.  Just be careful, your amp may not like the several nF of capacitance.
