Do speaker wires have to be the same length for each speaker?

In the mean time… one highly recommended speaker cable to consider (let’s see if I can get this right); HD12-3? Years ago either Stereophile or the Absolute Sound did a comparison of a number of low to intermediate speaker cables. They threw in a Home Depot extension cord… ends cut off. It actually sounded pretty good… didn’t win against $1K cables but sounded way better than lamp cord and Radio Shack 18” gauge speaker wire”. I loved the article it was great fun and informative. While I use $5K Transparent cables on my main system. I use HD12-3 on my office system… hidden because of the orange and black color behind my desk.

Sounds like you have a mold problem, ghdprentice. Just kidding... but are you serious about using an extension cord? It’s about $80 for 100 feet on Amazon; for about $10 more, you can get nice 10 gauge real live speaker wire.

Some speaker wires are custom cut and terminated/soldered and I guess if it was expensive enough you could save a few bucks with different length cables.

However I have OCD when it comes to my stereo with everything being lined up perfectly, no cables touching each other or the floor, etc., so for me they should be equal because there is some electrically measurable difference with different lengths that is not audible, but still "there". That's enough for me. I am sure we've all bought something that was supposedly better that we paid extra for that is not audible or detectable as an improvement individually.

I've got about 200 ft of good 12 AWG cable you can have for the price of shipping. Some is cut in length. I have two systems set up with it. It works very well, I was running it in about 30 foot lengths. Ask and ye shall have. White color.

I thought it always reads cut the speaker cables the same length. So if I have one speaker next the stereo and the other across the room.You can have one 3ft length and the other at the length you need ?

That's the UFC bout portion of this discussion, @limomangus .

Yes, you can have a pair of speaker cables of different lengths to a stereo set.  Technically, the % difference in electrical parameters of two different lengths of speaker cable is very small.  So there's arguments on both sides on whether it's audible or not.

For me, I wouldn't be able to discern the difference - too busy listening to the music.  However - the difference is still there (audible or not), so why not make them the same length if you easily can?  But also again, for custom installs or other extenuating circumstances which make it hard to keep both lengths the same - cut away!
