No one actually knows how to lculate what speaker cable they need


It goes back to cable manufaturars, mostly provide no relevant data! to sales and the users. None will answer this!
Whay do you think that you own now the optimal cable to your setup?
I think I've figured it out.

All this is eye-of-newt-and-toe-of-frog. Get good, rationally-engineered, not-too-expensive cables (I use Blue Jeans), and keep them matched in length and reasonably short.

I read through every single post, holding back laughing and crying the entire time. The OP of this thread doesn’t have the first idea about the science behind the transmission of amplified sound. Instead of wasting my time explaining to you all what is wrong with these posts... you can start down the road of real understanding by reading this-

I believe Transparent Cables does just what you ask - they take all of your equipment parameters and calculate the "perfect" cable specs for you. See? Your search is over.
