Engineers know very well that the square wave is the fundamental frequency with the odd order harmonics in proper phase very similar to music. And In music, the notes are complex waveforms, consisting of fundamental frequencies and harmonics very similar to the square wave. So if the loudspeaker cannot reproduce a square wave much less it cannot and will not reproduce music accurately. THAT IS A FACT AND NOT AN OPINION!
So the best speakers that I have ever heard are high power true minimum phase speakers that obviously reproduce square waves. This was accomplished using my own high power true minimum phase crossover that I personally design.
I was the Chief technician at Dunlavy Audio Labs and actually did accomplish what they call the Holy Grail of loudspeaker design, a flat amplitude frequency and phase response using a high power true minimum phase crossover.
