Mercedes-Benz CLS Car Audio Upgrade: Burmester 4D Sound

The Need for Premium Sound in a Mercedes-Benz CLS

For Mercedes-Benz CLS owners, the factory audio system, while decent, often leaves something to be desired. This review details an upgrade that goes beyond a simple speaker swap, focusing on the visually stunning and acoustically superior 4D electric Burmester system. We'll explore the installation process and the remarkable results achieved by Today's Car Incheon branch, a specialist in premium car audio solutions.

Expertise in 4D Electric Burmester for CLS

Today's Car Incheon branch boasts a team of experts specializing in high-end audio systems for luxury imports like Mercedes-Benz and BMW. Upgrading a premium sedan's audio is a complex task, involving precise integration of electric mechanisms, LED lighting, and acoustic tuning. With over 500 Mercedes-Benz audio installations in the last five years, their accumulated experience ensures a reliable and high-quality finish.

Before: The Limitations of Stock Audio

The CLS's stock tweeters are static and lack any dynamic visual element. The A-pillar trim, often plain black plastic, contributes to a subdued interior presence. Acoustically, the stock system struggles with high-frequency detail and soundstage depth, leading to a less immersive listening experience. The limited high-frequency output means subtle nuances in music can be lost, and the soundstage feels flat, lacking the precise placement of instruments. Furthermore, the stock tweeter's lighting often doesn't harmonize with the car's ambient lighting, creating a disjointed interior aesthetic.

Introducing the 4D Electric Burmester Tweeter

Burmester is renowned as Mercedes-Benz's premium audio partner. The 4D electric version elevates the standard tweeter with three key enhancements: a motorized rotating mechanism that deploys the tweeter upon ignition, integrated LED lighting rings capable of displaying various colors, and an audio-reactive spectrum analyzer where LEDs pulse with the music's frequencies. Beyond the visual spectacle, the optimized tweeter angle and output significantly improve high-frequency clarity and expand the soundstage, creating a more realistic and enveloping audio experience where instruments seem to be precisely placed within the cabin.

The Installation Process: Precision is Key

The installation begins with the careful disassembly of the CLS's A-pillar panels, a process requiring extreme caution due to the integrated airbag system. The electric tweeters are heavier and more complex than their static counterparts, necessitating a robust mounting solution. Torque specifications for the mounting screws, typically between 1.5-2.0 N·m, are strictly adhered to prevent damage to the plastic trim and ensure stability during driving.

Ensuring the smooth operation of the electric mechanism is paramount. The opening and closing speed must be consistent, and any operational noise must be eliminated. The technicians at Today's Car Incheon conduct multiple deployment tests before proceeding to the LED integration. This stage involves synchronizing the tweeter's LED colors with the vehicle's existing ambient lighting, such as the dashboard and air vents, to maintain a cohesive interior look. The audio signal input is also processed in parallel. This meticulous process typically takes 3 to 4 hours to complete, culminating in fine-tuning the audio equalizer (EQ) for optimal sound performance.
