A longer thinner wire will have higher resistance than a shorter t hicker wire of the same structure. An ideal wire should have the lowest resistance possible. To get the best energy transfer a thicker wire such as a gauge wire would be preferred over an gauge thinner wire.
Your decision should also be based on the length of the cable run and the impedance, or power requirements of your speakers.
Measure the distance from the amplifier to each speaker in the system and make sure to include approximately 4 to 6 feet of extra cable slack at each end. If your speaker has a nominal impedance of 4 ohms or lower and it requires a lot of power, so it is best to choose a 14 or gauge wire, despite the distance. This is why speaker wire has one side marked in some way.
Or, some other marking. Look closely and you will see it. Just make sure the side with the marking is connected to the corresponding terminal at either end. You can swap them around if you like. Is the same piece of wire connected to positive at both ends? Is the other wire connected to negative at both ends? However, if your cable and connections are a year or two old, and they look dirty, then it will do no harm to give your system a bit of TLC.
If you are using bare wire, then just cut off the end and strip a new section of insulation. That is, assuming you have enough slack to spare! Speaker wire inside a banana plug or other type of termination should be protected and clean. But, if the connectors on the wire — or on the speaker and amplifier — are dirty, then give them a clean. I have always used Isopropyl alcohol cleaning fluid. There are many brands that you can pick up cheaply enough. Tinning the bare ends of speaker wire can help to prevent oxidation and keep rogue copper strands in check.
But it also might make it harder to get a solid connection with a binding post or screw-in plug. A soldered connection for a plug might give you less chance of oxidation and a more reliable connection.
But you need to be sure your soldering skills are up to the job, or you might make it worse. Many banana plugs will have a screw-in connection which will work just fine. Just go with what you are comfortable with.
Not so fast. As with most things in the world of home theater, if you want to dig into the detail there are plenty of fun things to learn. As you now know, there are a few things that you should understand before getting some speaker wire.
First, work out how far you need to run the cable — and what the impedance of your speakers is. Then, you can purchase the correct gauge wire for your room. I would keep it simple and put that extra money towards a better amplifier or speakers. Search for: Search Button.

I have read in some places that you need to use the same wire lengths for your speaker pairs.
IE the Rear Surrounds should both be cut the same, even though one side or the other may have a shorter run to the reciever. Apparently using different lengths like the 16 and 22ft in your diagram would cause signals to be slightly out of sync between the two? Can you comment on this? If were were talking about very long lengths of wire or high power, it could be a different situation.

For higher power systems or longer lengths, 16 gauge is a great choice. Very long lengths of speaker wire lose a bit of power over the long distance due to resistance. Using larger wire can help reduce or avoid this. See my detailed chart later for more info. Wire Size Recommended For 18 Ga. Speaker wire length example 1. Speaker wire length example 2.

SpeakerCompare tailors your listening experience to the exact headphones you have, so that what you hear is comparable to auditioning speakers side-by-side in person. Two different listening modes. In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power.
In equal power mode, you'll hear these differences in loudness as they naturally occur between speakers. In equal volume mode, we've made the loudness of each speaker about the same. This gives you a more direct comparison of subtle voicing differences between speakers. Nothing beats listening to speakers in your space.
SpeakerCompare gives you a sense of the sonic differences. But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material.
