A merchant that can sell his products with a large profit to cost relation is actually rather smart.
I was in audio sales for more than 20 years.The percentage of those who bought unreasonably expensive cables or any other stuff (by anyone's standards)because of stupidity reasons,was very very small.
Don't worry, you can't

Someone who uses cheap cables has only a few $$$ to loose to have his cables equally long.......just in case

Don't get me started on salesmen
The power loss in speaker cable or any non coaxial transmission line is (I^2*R), current squared time resistance. Whether speaker cable loss is noticeable depends largely on the power level through the cables. Is it important if one cable is 4 feet and the other is two feet, not really. But if we are talking about 50 or 100 feet then yes it is significant and cable lengths should be equalized.
Some manufactures of speaker cable will boast of independent strands to reduce skin effect. This is bull because skin effect doesn't occur until radio frequency is reached and becomes increasingly more significant with an increase in frequency.
At the low end of the RF bandwidth it's not even a concern at all.
An 8 ohm speaker may have a DCR of around 6 ohm not including the complex impedance of the speaker. The DCR of a speaker is effectively in series with the speaker so your amplifier is always, seeing at least the DCR. This may very only by the crossover network in the speaker and number of speakers in the system. So at what cable resistance does the loss become significant?
Speaker cable follows the same electrical physics that any other wire does.
95% of all said about high end speaker cable is just marketing.
Do the math and make sound decisions.
This argument also applies to damping factor.

I hope you'r joking, really.

Simple math is simple. Do the simulations with accurate models and make sound decisions. Better yet measure. Many results of both have been already posted here.
When someone uses 3m of cheap cable on one speaker and 1.5m on the other,I wonder who's really joking

Everyone's a salesman, except for women because they are saleswomen. Ok, To be politically correct we are all sales people
Some are just full-time.
I squared R is the Voltage Loss! Not the power loss. Power loss also requires knowing the speakers impedance. With your 6 ohm DC load then .74 ohms would cause a 1db loss. That is 54' feet of 18 gauge. So your guess about significant length is not too bad.
So the home theatre folks who claim you should use equal lengths for stereo imaging are not nuts. They are just using too thin of a wire. Since I have seen supplied, by the manufacturers of low end home theatre, 22 gauge wire a difference of 23' feet will be heard by most folks. Place your TV in a corner and allow for up and down on the cable path, voila unbalanced stereo!
The skin depth for 10 gauge cable is 2600 Hertz! Maybe you think that is RF but most do not.
I understand there is way too much fertilizer on this thread but you might want to pinch your nose and wade through it. There is some useful material here.
