A real challenge to design a spectaculair object from a used brake disc. This bluetooth speaker proofs it is possible!  For this speaker I used a Ferrari F430 brake disc. The disc is cleaned, polished and protected with clear coat. The wear is still visible, showing it’s actual use on a Ferrari F430 Spider. Solid 10mm aluminum is used to form the stable base. At the back of the coaxial speaker is a aluminum case housing the amplifier and bluetooth electronics and also acts as a sound box. Powered by an external 12VDC power adapter.
