No one actually knows how to lculate what speaker cable they need

b4icu,
Many thanks for your advice. Presently I bi-amp the Kharma with a Telos 600 driving the 25mm diamond tweeter and 165mm ceramic mid and another Telos 600 driving the 330mm Nomex-Kevlar woofer. Is both cable the same at 4AWG? What if I move the amps closer to the speaker and have 1 m cables instead? Thanks 

b4icu,
for your info, presently I am using 2m Kharma KESL Speaker cable for both of them. Thanks 

Mr. khiak
Bi-wire is another urban legend, established in the 90’s. For a single cable at a X AWG is better than Bi-wire that the two, equals to the cross section or resistance of X AWG! This can be proved by simulation of the two circuits on "Spice". A cooper cable can conduct all audio frequencies at the same time. Some older TV designs, used wide band amplifiers, that would amplify two different frequency bande (IF and audio) to save.

As long as you are using your Telos 600, the wires need to be:
4 AWG@1.5m or
6 AWG@1.0m.

Can not find ant spec of your cables. Most are the Enigma...model. Also no Spec. 

b4icu,
I have been using this setup for the last 10 years and I am excited to hear a improvement for so little a cost. Thanks 

Mr.  khiak
You are welcome. All I'm asking in return, that you share with us your impressions from that exchange. Thanks.
How much did you pay for a set of 2m Kharma KESL Speaker cable?
