Any idea what's the principle behind this? They claim it gives deeper and rich bass tones even when the speakers themselves cannot physically reproduce them.

It's the principle of creating overtones of the second harmonic. in fact also known as second harmonic distortion, but they will not use that word because they are trying to use the overtones in a beneficial way. This is nothing new, maybe only in the way they process the signal. This is also the reason why many small bookshelf speakers are designed with a bump in the frequency responce in the 80-120 Hz region.

The principle relies on the psychoacoustics of the human hearing. When a instrument tone of 40Hz is played there are always 80Hz second harmonic elements. The human ear "thinks" that it's hearing only one tone. When you add more overtones, your ear (well actually your brain) will "think" it's hearing the 40Hz tone playing louder. Funny thing is that you will only hear the inmediate difference when there's a real 40Hz tone played at the same time, you will inmedialtly recognize the other one as being false.

The harmonic intervals of a note imply the fundamental, e.g.
80Hz has harmonics at n x 80, ie. 160, 240, 320 etc....

If you add in harmonics between these e.g [(n x 80) - 40] to give
the series 80, 120, 160, 200, 240, etc.... this implies the presence
of a fundamental one octave lower.

But you don't need to reproduce the fundamental to imply
the note, of course its sounds much more real if you do.
