The optional second Deep Speaker provides more volume and a better distribution of sound. Comparable to a mono or stereo sound, a second actuator provides for better sound characteristics.

The High Tone Booster (included in the Stage one PLUS kit) is a perfect addition and a must have to the set. This speaker reproduces the higher tones and adds a brutal new voice to the sounds. The misfires become incredibly louder. Sound and misfires gain extreme authenticity through this speaker. For the coming custom sounds it is a absolute must have! No worries, you easily can upgrade this any time!

Realistic Sounding


Not only will the vehicle enthusiast's heart beat faster, goosebumps are guaranteed!

Why only engine or e-sounds?

With custom sounds you can expand your active sound system with another great feature! With the embedded scene control, you can also play other sounds. Depending on the vehicle you can specify to play different sounds by locking or unlocking your car or to replace the horn of your vehicle with a train horn or a horn of a beetle, just by clicking on your app! The possibilities are endless and the sound selection is constantly expanding.

The App - Control Center

App controled

Connected via Bluetooth, you can use the app to make countless settings and change sounds.Software updates and new sounds can be easily and quickly loaded via the app and guarantee a future-proof system without compromise.

Vehicle Integration

Why install buttons when your car already has them? Why use a remote control when your car is the remote control.

Since the beginning of the Active Sound development, it was our ambition to integrate the system perfectly into your car.

Through our app, you can create different driving profiles and assign them to specific buttons in the car.

For example, depending on the car's equipment, you can activate and deactivate your sound via the CANCEL button on the cruise control. It is also possible to change profiles via the ESP button without losing the function of these buttons.

No restrictions. Full control, even while driving, safe and fast.

Electric Or Hybrid

The signs of the future are set and we are also moving with the times. Our software supports both fully electric and hybrid vehicles.

For the engine sounds, we simulate a synthetic RPM and gearshifts based on speed and accelerator pedal position. With these values we then generate an authentic engine sound that gives you the driving experience of a combustion engine.

Road safety also plays a very important role, as the first electric vehicles had no sound at all and the newer ones usually only have a quiet whirring sound. In traffic, these vehicles are little or not noticed and therefore pose a very high risk of accidents for pedestrians and cyclists.
