You don’t have to be a diehard Porsche fan to appreciate this awesome item. A twin-exhaust outlet and resonator from the 500-horsepower 4.0-liter six-cylinder engine found in the 911 GT3 forms the basis for this Bluetooth-enabled speaker. The 200-watt unit, which weighs in at 40 pounds, comes with bass and treble controls, Dolby digital decoder, LED display and a remote control. Both coaxial and optical inputs are included, as is a sub-woofer output and a plaque with an assigned limited-edition number indicating which of the 911 (total production) speakers is in your possession. Purchase for 3,500 Euros (about $3,800) from www.porsche-design.com.
