It’s rare to find someone who’s a stranger to the stylish features of the Golf GTI. But if you’ve taken a ride in the sporty hatch and had the chance to listen to some of your favourite tunes, you’ve probably realised how incredible your music sounds in the car. This is thanks to its Dynaudio Excite system which produces the purest bass and crystal-clear treble.
As Michael Ewerts, Vice President of Sales (Automotive) from Dynaudio explains, “We think how you listen should be every bit as engaging as what you drive. The Volkswagen Golf GTI is a high-performance car – so we gave it a high-performance audio system.”
We concur. So how do expert sound tuners decide on what’s the best sound system for your car? Read on to find out more!
The first step in developing the perfect sound system for your Volkswagen is finding out how to best integrate the various audio components. These components or ‘speakers’, produce sound of different frequencies and produce what we know as music when they come together. These include tweeters, woofers and even mid-range drivers. As such, the sound engineers are tasked with the important job of measuring these components and identifying potential challenges in the vehicle’s environment. This gives them a better idea of how the cabin absorbs and reflects sound. A lot of time is spent listening and measuring which is crucial for perfecting the whole system.
Sound engineers open up a programme to review their code, make alterations to it or move the distance spacing between audio units with down to as little as .02ms. The new tuning is then flashed onto the amplifier to a/b test changes instantly. In this instance, a/b testing refers to when sound engineers compare two sound samples to determine which is a more suitable solution for a specific vehicle.
Did you know that the Golf GTI comes fitted with eight speakers specifically designed for the car’s interior, along with a subwoofer, a digital 10 channel amplifier and 400 watts of output? Its Digital Signal Processing also adjusts sound emissions from every speaker according to its position in the car – so you hear sound as if you are in the ideal listening position each time.
However, because there aren’t any programmes that can tell you where to move those milliseconds or where the frequencies should be delayed to sound just right, the sound tuners have to rely heavily on their own ears. They have to be able to tell when the directionality is off. This allows for a more natural sound experience – especially in an environment with various reflective surfaces.
A final round of a/b testing is then conducted so sound technicians can evaluate two tunings. They are able to switch between them effortlessly to decide which sound experience best suits the drivers and passengers of a particular car.
A common misconception is that the subwoofer alone reproduces low frequencies – it doesn’t. It works together with all of the woofers to produce high-quality bass performance that is even and rich in detail throughout the car. A subwoofer’s main job is to eliminate standing waves in the cabin so you don’t get too much ‘boom’ in low frequencies.
The car is then presented to the Volkswagen team and further changes are made. The teams then work together to solve any issues or change the tuning altogether before the final product is ready! The sound system of each individual Volkswagen is then tuned to ensure the best possible audio performance for every driver and passenger.
