The Porsche 911: the car that shouldn’t work but does

Humanity might struggle perpetually with questions like the meaning of life, but it does know one thing for sure: rear engine cars are bad.

CES: Cranking up Harman's QuantumLogic 3D surround-sound system

Yesterday we reported how Audi was readying a lavish 3D sound experience with 23 speakers and 1,400 watts of goosebump-inducing audio power. Not to be outdone, Harman had been quietly developing a system of its own: Quantum Logic 3D brings together 25 speakers and more than 2,000 watts of Tubthumping power to a new car near you, like driving inside Phil Spector's Wall of Sound. Sitting inside the demonstration BMW 7-Series that Harman painstakingly lifted into the Studio at the Palms, Global Audio Engineering vice president Phil Muzio explained, "great music is delivered in stereo, yet our consumer research indicates that people enjoy surround sound." QuantumLogic 3D's surround sound expands beyond the boundaries of the vehicle's cabin, providing "a sense of detail and spatial placement that you don't get in stereo." Five height component speakers mounted in the corners of the headliner, and above the rearview mirror, elevates audio beyond the confines of the roof, "almost like you're in a convertible," said Muzio.
