Second biggest myth I think is subwoofers (having experimented with a few). Vast cost for a tiny percentage of the audible spectrum.
Don't really agree that it's a tiny percentage. Say you're young and healthy and can hear 20 Hz to 20 kHz. That's about 10 octaves. If you set a sub to do everything below 80 Hz, that's 2 octaves, or 20%. Those 20% are also the most energy demanding octaves to reproduce. While the cost is high, subwoofers do some heavy lifting in an area where there's a lot of energy from bass drums, bass guitars, double basses, percussion, movie explosions etc. But I'll readily agree they need careful integration in normal size rooms.
My favorite hi-fi myth is ethernet regenerators. Or, they're not a myth, they're a total scam!
