To add to pburant's post, I'll throw in the following:The speaker, when listening to the music of more than one instrument/pitch at a time, doesn't really have to vibrate at a certain frequency so much as it has to trace the waveform of the signal going through/to it.
If you've ever seen an oscilloscope, or similar device, hooked to either a microphone, or passing a musical signal and watched the "waveshape" of the music go by, all the different sounds combine into one waveform made up of many different frequencies. If the speaker's cone and voice coil follow that electrical signal accurately, you hear "the music".
So, getting a speaker to play one specific frequency is a lot different from having it play a recorded musical signal (more than one instrument/pitch at a time). In fact, it's been my experience that getting a speaker to play recorded music is a lot EASIER than getting it to play one specific frequency, such as a bass guitar speaker for example. If we had to build our home speakers out of really GOOD quality musical instrument speaker drivers, most of us would freak at how much that would cost.
Usher 8" carbon fiber/paper woofer: $140 (good home audio woofer)
Electro-Voice 15" woofer: $718 (pro audio driver)Oddly enough, most speakers built for pro audio use STINK and home audio, and most home audio drivers are not even usable at all as musical instrument/PA drivers, they just can't handle it.
