知少少，扮代表。

響網上抄番泥的資料。 :a008:

第一幅圖，係有關

(上面個表) 十二種樂器的頻應範圍

(下面個表) 唱古典人聲的頻應範圍

【由上至下 : 男低音、男中音、男高音、女低音及女高音】

注意 : 以上頻應，只顯示基音的頻應範圍，

不包括任何泛音（可以比基音更高或更低）。

So piano is good for testing the system.

Even for piano, the 基音 range is still quite narrow, within 5 kHz. So what is the point of having "ultra high frequency" speakers in pure music listening? To hear 泛音?
恕小弟無知~

你講得有道理。

但係 dak2000.com 有篇文章 Drew's Equalizer and Frequency Equalization Tutorial 就有以下說法 :

果篇 article 寫:

... it's the fundamental that what we call the actual note. And when you use a tone generator or test disc to generate a sine wave of say 440hz, it's the fundamental note alone without harmonics ...

果篇 article 又寫:

... Of course music is composed of thousands of frequencies all sounding at once. But that doesn't change the fact that it's composed of individual tones ...

果篇 article 又寫:

... Given the often-talked-about musical range of 20hz-20khz, it is surprising to see just how low the musical fundamental frequencies actually are (almost all are under 3,500khz).

But remember, ...

It is the harmonics that give each individual instrument its character, or timbre, and set it apart from all the rest ...

果篇 article 又寫:

... Interestingly, the human ear is more sensitive to certain octaves in the musical spectrum than to others. The ear is tuned more toward the midrange frequencies, where speech and voice communication occur (I guess we're still cave people), than to the outer octaves of low bass and high frequency musical harmonics.

As a result, very small energy changes in the midrange frequencies cause much more noticeable effects than do larger changes in the very low and/or very high frequency ranges ...
