Here is a Bluetooth speaker made for F1 fans. The Pirelli P ZERO Sound System is a speaker inside a scaled-down F1 tire. It has an amplifier with a 100-watt digital signal processor. It comes with a 100-millimeter midwoofer and a 25-millimetre silk tweeter.
This speaker system measures 13 x 7.8″. The bad news? Something like this doesn’t come cheap.
