Coiling excess Speaker cable, is this a problem?


Hello!

I have a question that maybe you could help me with. I have been told that you should keep the lengths of speaker wire the same to each speaker. As a result, I have 2 (BiWired) cables going to each speaker, due to my system set-up, I have about 8' of two cables neatly coiled up next to my system rack. Though I am not detecting any sound reproduction artifacts, are there any potential deleterious problems I may not be aware of? I did take a photograph of this but I could not figure out how to paste it here.

Thanks for your help!

Especially not cables that are already bi. They may decide to go trans.
Thanks for the response!

Still a Noob here, where/how can I find the discussion about coiling excess wire? Also, what does it mean if cables are about to go trans? I'm trying to figure out how to best dress the coil of wire and am looking for suggestions.

Most appreciated!
@grm sorry if some of the responses tend to be less than cordial or helpful. Coiling your cable acts like an coil in a crossover and tends to roll off high frequency response. So we would like to avoid that. This is one reason I like DIY cables that I can custom make to my exact needs. Very tidy, sonically better.
If you have expensive cable, Contact the maker and see if they will cut to proper size and re-terminate for you. You may be able to do this yourself but resale value will be affected.
Coiling would have negative effect for single wire, by adding inductance.  Coiling cable is different - it creates common mode choke that has inductance only for common mode signals.  For normal mode (differential) signals current in both conductors has opposite direction, producing cancelling magnetic fields, hence no added inductance.  The best test for it is to try it both ways and let us know.
