Each week Tom Whitwell of Music Thing highlights the best of the new music gear that's coming out, as well as noteworthy vintage equipment:
For car audio freaks, bass is a weapon. Search YouTube for 'subwoofer' and you'll enter the slightly alarming world of extreme bass - clips of girls' hair blown up by the bass, and speakers catching fire under the load.
For audiophiles, bass is expensive. The biggest subwoofer in the world is an underground chamber containing 16 eighteen-inch speakers, built underneath what they call "the greatest audio room for private listening in the world". Incredibly, the sixteen speakers are all driven by one eleven-watt tube amp. That's eleven watts, not eleven kilowatts. Awesome.
