A newbie with a speaker cable AWG question.

Ohlala, our ears aren't garbage pails.

Tooter, some of the best cable that I am aware of are the Audience Au24 and the Audio Tekne ARSP 500 speaker cables. Both cables are about as thick as your keyboard cable.

So you don't have to go the anaconda route.

And the two seem to be quite similar in sonic characteristics.

-IMO

Tooter:

To respond a bit more directly to your question: you will not be using "overkill" if you choose a 10 AWG speaker cable, but it may not be necessary to use such a heavy cable. There are two issues here:
1. the length of the speaker cable (from the amp to the speaker);
2. the speaker you are using (full-range speakers with large woofers draw more current, so you may need heavier gauge speaker cable).

For the sake of discussion, you are usually safe with a 14-gauge speaker cable if your cables are 8 feet or less in length. As your cable gets longer, you want to increase the wire gauge. There are no "absolutes" about length vs. gauge, but I usually advise using 12-gauge speaker cable if the amp-to-speaker distance is more than 10 feet, and 10-gauge speaker cable if the amp-to-speaker distance is more than 15 feet.

The actual thickness of the cable (internal wire plus outside wrapping/insulation) can be a potential issue if the cable is so thick it's hard to bend, or so heavy that it causes smaller monitor speakers to become unstable on their stands.

The AWG of the speaker cable is not the only issue, however. With heavier, longer runs of cable, you should pay attention to the electrical characteristics of the cable, particularly resistance and characteristic impedance. There are a number of good speaker cable manufacturers, and it would be a good idea to look at the specifications of the cable before making a final choice. There have been a lot of threads on this topic, so you might want to search the A-gon archives. Try looking under "speaker cable gauge", "recommended speaker cable", or something similar to find the threads.

Thanks for your responses Ohlala, Stehno and Sdcampbell. Sdcampbell - You bring up important points. I guess when I asked about "overkill" I was trying to ask if it's possible to have too low of an impedance for a very short run of speaker cables. I understand that as you increase length of cable that issues like resistance and impedance become important. I guess my question is if you look at the various cables within any given speaker cable company's line, it seems that as the price goes up so does the cable thickness and "technologies" used. In my set up I only need 6 feet runs so are you saying I won't hear as much of an improvement the further up I go within a given line of products? Am I oversimplifying?

Tooter:

With short runs of speaker cable, it is less likely that the electrical characteristics of the cable will have an audible effect. However, cables that are better designed will -- in all likelihood -- sound better than cheaply designed cables. You didn't indicate what your budget is for speaker cables, but there are a lot of good choices in the moderately priced range. Again, I suggest that you look in the A-gon archives for specific comments about the better cable brands and models, and then (if possible) find a dealer that will let you audition the ones that interest you.

See this link midway in the page with the paragraph that starts with "There is a common misconception that loudspeaker cable must be large in diameter ...":
It works for me.
