Part of the secret is in the long-throw speaker technology. Conventional speakers have large surface areas and dont move in and out very far. Long-throw speakers have small surface but can travel far out and far in. They can move large volumes of air, and this is what you need for bass so low that it is felt rather than heard.

Also the tiny treble speakers do a good job with the frequencies that carry speech information so vowels and consonats come through clearly
