So you are looking for a speaker that turns heads? The Pirelli P ZERO Sound System is worth a look. It is a Bluetooth sound system made for F1 fans. It has a speaker inside a scaled-down F1 tire (wind tunnel tire). These kinds of tires are made by Pirelli for Formula 1 teams to conduct their aerodynamic testing.
The Pirelli P ZERO Sound system has an amplifier with a 100-watt digital signal processor, 100mm midwoofer and a 25mm silk tweeter. The bad news? Something like this doesn’t come cheap.[HT]
