The soundfiles

In the development of our Active Sound, our goal was to generate the most realistic vehicle sound possible. We spared no expense and effort, recording real vehicles on a high acoustic test bench. We promise an almost lifelike sound experience that is second to none.


The method

The Panthera Leo Active Sound Generator is globally unique because data acquisition occurs wirelessly via the OBD2 interface. The adapter transmits this data to our sound module via Bluetooth. In its latest version, the Leo 6.0 features a sophisticated audio engine capable of reproducing genuinely recorded engine and exhaust sounds. Additional effects like 'Realistic Mode,' throttle or load-dependent volume, and simulated 'misfires' can be activated as desired.

The installation

Thanks to our OBD solution, installation is quick, easy, and straightforward. The sound generator can be mounted as desired, either inside the vehicle's interior or in the exterior area. Power is supplied through a simple connection to ignition plus using provided adapters (Plug&Play). Subsequently, the OBD-II adapter is plugged into the vehicle, and the rest is handled wirelessly by the system. Since no changes are made to the original vehicle electronics, and no soldering or crimping on the CAN bus is required, installation can be performed by individuals with technical knowledge. Reverting to the original condition is always possible. We guarantee that our Active Sound System does not cause a loss of your vehicle's warranty.
