I'm a couple of days off installing all the speaker cables in my dedicated 7.1.4 cinema room. What are your thoughts on speaker cable length to pairs of speakers, I've always made them the same and just coiled the excess but is it really important? My head is telling me I should I should just do what I've always done. As an example my atmos fronts, I can get away with 1 cable being 2.2m shorter and the same for the atmos rears. Thoughts??
