Another cable length question....

I looked over all the previous posts and it is obvious that the answer is the shorter the speaker cable, the better. However, what is the longest length I can get before the sound deteriorates too much? Currently, I use 15 ft Signal Cables and they do just fine. However, my system has been moved to another room and although the speakers are not that far away, the connection between speaker and cable is too far for the 15 foot cables. I actually have to run one cable over a door way to keep people from stepping on it. This leads me to need a cable slightly longer that 15 foot; otherwise, the 15 footer is too taught as it is. The new placement of speakers will work for me but the cable length is causing me concern on good sound.

Can anyone help?

I have to use, currently, lengthy runs of speaker cables myself.

Using various speakers, amps, and speaker cables from DIY to premium cables of 20-30ft. I've experienced no perceived attenuation of upper band information. Wire gauge was kept fairly large though.... but not immense. #8 AWG stranded, being the largest I’ve tried out right..

If I’m actually losing something, either it isn’t much or it doesn’t matter to me apparently.

I've run combinations of amps & speakers from 60 wpc into 4 ohm units that drop lower by half, and other more powerful amps and easier to run speakers. No problems occurred I am aware of.

I did notice spending more on speaker wire helped improve the sound.... and now use SR Sig 10 x2 active biwires. I believe a good reason for that is the termination, and dialectric. The Sig 10s too, are a bit beefy, though I don’t know their actual AWG, outright or even it’s effective overall gauge.

The technical info Al input I'm sure is quite valid and I'm not disputing it, but you must see for yourself how the changes in speaker lengths with your gear might be. There are also devices which can protect your cables from being smashed which lay on the floor and the wires run right thru them. Wiremold among others make such things, and that could save you 10ft or more right there in wire lengths.

A hole in the wall will too. Ultimately, that’s what I did and still must use 21ft cables…. Until I reroute some power ckts. I’m in no hurry to do it though.

If you could make, rent or borrow the same but shorter cables and just reposition the gear temporarily, you’d see for yourself what is truly the diff by comparing the short ones to the longer ones.

Some perspective should be gained here for your own now and future benefit, if nothing else but to keep in mind some rule of thumb for yourself.

My longest runs are 36FT. Until recently my Onkyo 805 receiver was driving them and the center ch without trouble, yielding pretty good results with Canare 4S11 cabling.

Audio nuts go to extremes sometimes. Now and then, the issues are only in the mind of the nut doing the task, and not demonstrably noteable if done in a more practical fashion in reality. We do like overkill.

Shorter wire paths are better, no doubt. They aren’t always possible however. We can only do what we can do, and little more if at all. I’d keep the AWG up somewhat as Al points to here and past that, be more mindful of the fact cabling from maker to maker will produce sound differently more so than will the lengths if and as well, are kept appropriate.

I’d not lose any sleep over it though, given it can’t be helped much now. I'd look to protect the cable while on the floor if that will shorten or ease the strain some.

I wonder too sometimes, if all the rhetoric on cable lengths wasn’t promoted by their sheer costs…. Wherein, shorter equates to cheaper too and especially with speaker cables. Lol Usually you’ll find long ICs + shorter speaker wire less costly, than doing things the other way around. Good luck.
