Most amp are voltage source (low output impedance ) so keep R and L low ,but it's not hard to do . Skin effect has little influence in analogue audio so it is LCR parameters only for low-frequency applications (audio is lf it's not radio or radar ) ,most amps zobel ? networks on the outputs makes z rise at higher frequencies anyway . But R dominates RLC is the prio order for speaker cable. I think it is CLR for signal wire The most simple way is to keep them short,when I had passive speaker the power amp was between speakers and wires never longer than they needed to be. Once i had mono blocks then I used 0,5m speaker cables . The classic kimber 8TC and 4TC uses this effect low R and L not so low C , note some unstable amp design can have problems with this, but it's not a cable problem it's an amp problem (flawed design) . People with planar speaker or other speakers with very low impedance can have noticeable frequency deviations with to tiny gauge speaker wire some speakers are ridiculous ! down to 1 ohm or similar. Short avoid the smallest gauges same leght to both speaker if you are being ocd about it. Don't coil excess length to a bundle, you just made you own air core inductance, cut it of . If can't afford to cut your speaker wire you put to much money in it imho. -- Mnyb -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
