Active Sound System

Maxhaust Set
The Maxhaust Active Sound System simulates amazingly realistic sounding engine and futuristic e-sounds via the vehicle's characteristics, such as engine speed and load.
Diesel, gasoline engine or electric car? With our set a sonorous, rich exhaust sound can also be retrofitted to your vehicle!

The Technology

Sound Booster

Sound Booster

The interface between vehicle, sound module and app.
Maxhaust Sound Booster
Via the CAN-BUS of your vehicle, the Sound Booster reads all relevant data such as speed, accelerator pedal position, load, etc., processes them in real time and passes them on to the sound module.

The vehicle buttons are also processed and depending on the vehicle type, the Sound Booster enables control via the buttons such as cruise control, ESP or if available also via the driving profiles such as Comfort, Eco, Sport.

Connected via Bluetooth Low Energy (BLE) you manage all sounds and their numerous settings via our unique app. Since you are not allowed to use a smartphone while driving, you can save these settings in profiles on the Sound Booster and then control them via the vehicle buttons from your car without having to touch your smartphone.
The Perfect Integration.

Different sounds in one module

Our sound module, made for more!
Maxhaust App
More power, more sounds, more possibilities.
Using a highly complex algorithm and the latest DSP technology, the processor handles our specifically developed sounds. Our engineers develop realistic sounds from real recordings of the best engines in the world.

Clear reproduction through 4 speaker channels guarantee a rich, voluminous and unique sound experience. Misfires are reproduced deafeningly real and give you a feeling that you will not want to miss.

...loud, louder, MAXHAUST

More volume

Discreet or would you like a little more?
Speaker set
Different speakers for different needs.
The speaker (actuator) included in the complete set is housed in a steel cabinet and provides a decent rich sound that can be easily adjusted above the 100dB limit if necessary.

You want more? Then simply choose the additional actuator that suits you from 3 optional speakers.
Deep Speaker
The optional second Deep speaker provides more volume and a better distribution of sound. Comparable to a mono or stereo sound, a second actuator acts for better sound characteristics.
The High speaker is a perfect addition to the set. This speaker reproduces the higher tones and adds a brutal new voice to the sounds. The misfires become extremely louder. Sound and misfires gain extreme authenticity through this actuator.
High Speaker
Deepsound
The Vibration speaker spreads sound waves through the engine hood and reduces the well-known nailing noise of diesel vehicles. Mounted on the intake of the interior ventilation, the sound waves deliver a discreet sound in the interior.

The App functions as Control Center

App set
Connected via Bluetooth Low Energy, you can change countless settings with the app. These include:
Volume adjustment
Idle and drive volume can be adjusted independently for each speaker. This allows you to precisely tune the volume levels in each area of the vehicle
Speed-dependent volume adjustment (DALA)
When this feature is activated, the lower RPM range is turned down and the full volume slowly unfolds as the RPM is increased. This function gives the sound an even more realistic touch.
Idle speed
Idle speed can be increased and decreased without affecting the original speed of the vehicle.
Load loss
When this function is activated, the lower RPM range is turned down and the full volume slowly unfolds as the RPM increases. This function gives the sound an even more realistic touch.
Unsteady running
Idle is too monotonous? Turn the knob a bit and listen how the idle sound becomes more irregular and authentic
Sound-dependent RPM
Should the engine speed match the vehicle speed or should it be a bit more? Adjust the engine speed according to your needs.
Misfires
When should the misfire be triggered? Already at 1500 rpm or only at 4000 rpm. How often should it be triggered? 1 time or in random sequence up to 5 times?
Equalizer
The term is surely known. Here, in addition to the bass and treble, the intensity and a distortion can be adjusted

Other functions of the app
The app can do quite a bit more. In addition to a full diagnostics function of the system including help with errors, you can also download updates and new sounds.

Through our unique remote maintenance feature, we also have the ability to read your vehicle's CAN bus data in real time through the app, allowing us to troubleshoot or add new vehicles in the software
Profiles
Custom profiles can be created and named. These can be assigned to a sound and above functions can be stored individually to these profiles.
Start Profile
You have created and set your profiles? Here you can set which profile your car should start with or you can use the memory function and your car will always start with the profile you turned it off with.
Adjust volume while driving*
Preferably the plus and minus button of the cruise control is used for this function.
City / highway function*
In the city mode, your system automatically deactivates when you exceed 75 km/h and activates again as soon as you break down to 50km/h. The highway function deactivates the system when you reach 120 km/h and reactivates it again when you go below 75 km/h.
Demo mode
You want to use the system without starting the engine or you are a car dealer and showcase the system in your showroom? You can! Just connect 12Volt and start the sound via DEMO mode. Also accelerating is possible within the app

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 the 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.

Installation

Do it yourself or have it done.
We help you with your decision and are always available with advice and support.

Depending on the vehicle the speakers are installed either in the trunk or underneath the vehicle. Depending on how much space is available in your car.

There will be either welding work or drilling to lead the sound tube out of the cars interior.

The electrical system is very easy to connect. Besides power and ground, only two cables are connected to the CAN-BUS.

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.
