We read and hear all the time profound "truths" about this hobby of ours, some true, some false, some so outright exaggerated that we can't stop laughing.
If you know some good ones, this is the place to expose them to the elements.
Let's have a good collection of them.
Let me start:
The volume at which you play the music is exact if, when you go to another room, you can say that the band or singer is really present and playing in that room. True? Yes.
Another one: just like trimming the length of the quarterwave elements in a dipole or yagi antenna to exactly the same lengths is of the utmost importance, specially for transmitting; the wires transmitting the signal from the amp to the speakers must be exactly the same length. True? No.
