The Panthera Leo Active sound generator queries all data relevant to sound generation from the vehicle’s engine control unit in real time via an OBD-II adapter. The adapter transmits this data wirelessly via Bluetooth to our control unit with an integrated audio amplifier called the Active Sound Cube. In its latest version 5.0, the Cube has a complex audio engine which is able to reproduce real recorded engine / exhaust noise.

If desired, additional effects such as “Realistic Mode”, an accelerator pedal or load-dependent volume and simulated “misfires” can be activated


Thanks to our OBD solution, assembly is quick and easy. The loudspeaker of the Active Sound System can be installed in the vehicle as well as outdoors as desired.

Up to four speakers can be installed if required.

Power is supplied via ignition plus and permanent plus via the supplied adapter (plug and play) on the vehicle fuse box.

Then the OBD-II adapter is plugged into the vehicle. The system does the rest wirelessly.



The Leo sound generator is a wireless-data-transmission
Active Sound System which transmits the relevant data by radio.
