SF, you're probably referring to Bren's warning about coiled speaker wire forming an inductor, and you're happy that now you have one more thing to worry about. Unshielded wire in a coil(I assume that you're speaking of part of the wire that's connected to the speakers)does in fact form an inductor and the resulting inductive reactance in the wire opposes the signal flow in direct proportion to frequency, i.e. higher frequencies are reduced proportionally more. This effect is used in speaker crossover networks when the inductor rolls off the high frequency response to prevent it from reaching the woofer. A little of the same effect can occur by simply tightly coiling excess speaker wire(the number and tightness of the coils are among the factors involved)and it's sometimes suggested to zigzag it rather than coil it. The loss of high frequency response from a few loose coils probably isn't audible, but good practice is to keep speaker leads short in general and uncoiled if there's more than is necessary for the run.
Then of course, for the ultimate in audiophile nirvana, you should buy at least a dozen of the cable supports shown in the link Peter provided.
