Zaph shows distortion too Zaph|Audio
To sum this - like Bob said in post #1, it is the harmonic distortion we hear from frequencies (notes) below 80Hz. The secret lies in high distortion.
There is also quality aspect - that elevated harmonics distort the sound of instruments! This is where large drivers shine!

Low E and even B fundamentals ( of a bass guitar ) are very audible or it would sound just like a guitar!
There are a few severe misconceptions here regarding 'distortion'
An organ mote of say 25Hz will mostly consist of upper harmonics. If you filter out the fundamental yes you will miss something, but you are left with the upper harmonics (if the driver is capable of producing them). A large subwoofer will actually 'distort' the sound more in this repect as it is not producing these upper harmonics. This is severe harmonic distortion. Distortion is really any deviation from the natural harmonic structure (amongst some other things).
If you play your lowest organ note on a 3" then you will miss the fundamental, so yes this can be considered distortion but not because something is added, but because something is taken away. Harmonic distortion is normally associated with unwanted higher harmonics so it is debatable whether this is harmonic distortion, unless you are introducng unwanted or changed upper harmonics. A large sub will produce severe harmonic distortion for anything other than a pure bass sinewave in its designed frequency range.
If you feed a pure sinewave into a 3" and get anything but a sinewave out then you are getting distortion (unwanted higher harmonics). So the distortion you will hear from a pure bass note is to do with unwanted upper resonances in the driver. From any musical bass note (containing complex upper harmonics) its also to do with the accuracy of producing these harmonics (bandwith capability amongst other factors).

I really am sorry I started this thread. What I intended was 1) Why so many DIY'ers report that their tiny little speakers have "good" bass. and 2) there are things that no small driver can reproduce -- i.e. plot 3 on post 1. So now we have 60 post proving that a 3" driver is not a 12" driver. Very good! Well done.
