Yes it will. That is what I did [Kinda the were 4/14] for my surrounds which has an effective gauge of 11. You're good to go. Now just do it.

Probably already had this answered, but I would use 10 and/or 12 guage, 10 guage is nice though just for a guarantee that you have a quality cable for your speakers.
Think of speaker cable like a pipe. If the pipe is 2 inches in diameter it can move much more water a lot easier with less resistance the longer the wire, the more resistance, the weaker the signal etc.... if the pipe is 1 inch in diameter, your water (power to the speakers) is going to be very restricted and have higher resistance, this would be the case with something like 16 guage at 50 feet.
12 guage all around for my speakers, 10 guage for the fronts, they also have the longest run though. And soon I will be putting one of my amps in front of the theater under my screen and then running wire from it to the new fronts. (since the 120 amps of current per channel will surely need a much closer run, and thicker cable  )
My 2 cents, good luck on what you decide!

Ouch. This seems to directly address my post, LOL. There are formulas for sizing wire in speaker systems. And although, generally speaking, running a larger wire will not directly harm anything, there is a slim possibility it can damage your amp. But, that's what keeps me in business, LOL. How many times have I heard, "I don't know what happened, it was playing fine and then a speaker stopped playing."

Larger wire damages an amp?
I call bull****.

Precisely what most think. And I said "slim possibility".  But, like everybody else you can think what you want. I'll just wait for them to show up on Ebay........

Yeah and there's a slim possibility I will hit the lottery...because I do play. Those kind of odds sound about right Mac?

Why sure there is a possibility you can win the lottery, "IF" you play. Tell me again how many bad amps are on Ebay, and in repair shops.......
I could give you the technically proven reason as to why but it's more fun posting back and forth.... LOL.

The reason isn't the gauge of the wire, it's how it is installed on the binding posts most, if not all of the time. Too much wire stress the binding posts by pulling down on the posts...or a stray strand grounds out the wire. It is not just because the wire is a larger gauge.

I base my wire guage off of how many amps of current are going to the speakers, since my equipment puts out some hefty amperage I use hefty wire. I don't think a 16 guage wire would last with 120 amps of current going through it, but thats my opinion.

For my pro equipment and others who I repair pro equipment for which has outputs of 400, 800, 1000, 1500, 2000 watts driving horns, 15's, 18's, at lengths of 25', 50' and 75' and at times of very high volume and always run either 14 or 12 gauge wire.
The only thing I can suggest is that some do some reading on amps, resistance, capacitance and impedance and then on speaker impedance and wire resistance and capacitance. You'd be surprised.
But, as I said before, run what you want. I surely won't mind......

Actually only 1 of your links indicate this. The other 2 are the opposite.
Did you ever wonder why all these sites don't just say, "run 10 gauge for everything" of even 12, just run all 12?
Confucius says..... resistance can be your friend......

Actually I just reread that 1 questionable 1 and that one doesn't say that either. Not that I'm picking on you Nash.....

Horse Hockey. Run 10 for everything it just works, all you’re doing is obfuscating a simple issue; get the power there with as little loss as possible.

That's OK so am I . This is the last line from the parts express article
| Part express wrote: | Gauge acceptability for run lengths are noted above in red. Pro Co’s recommendations are to use 16 gauge under
25 feet, 12 gauge under 100 feet, and if you can afford it, use 8 gauge everywhere. |
15 love. It's your serve.

I think thats the biggest issue - Price. If wire was more affordable I don't think many people would be using spaghetti to power their speakers.
Theres a lot of things to take into consideration when running thw wire, but 12 guage I find is usually the most reliable, 10 guage, well... I only have my 2 fronts on 10 guage, so far I havent had any amps cook, speakers fry, etc etc...
More wire strands, thicker guage, usually = better current/power flow, less resistance (kind of like 2+2=4  ) Also dont forget about the purity of the copper being used in the cabling.
