The Burmester 3D speaker set is a meticulously engineered collection of acoustic components designed to deliver immersive 3D sound in Mercedes Benz vehicles. Tailored to specific models (from C Class to S Class), each set comprises a curated mix of speakers optimized for the cabin’s unique dimensions and materials. A typical setup includes 4–6 silk dome tweeters (25mm) for high frequencies (2kHz–20kHz), positioned in door panels and A pillars to create wide dispersion. Midrange speakers (165mm), often with aluminum cones, handle 200Hz–5kHz, mounted in doors and dashboard to anchor vocals and instruments. Subwoofers (200mm+), using rigid carbon fiber composites, deliver bass (30Hz–200Hz) and are integrated into the vehicle’s structure (e.g., rear parcel shelf, spare wheel well) to leverage cabin resonance. The defining 3D element is overhead speakers (100mm) in the headliner, adding vertical depth by reproducing height cues in music or movie soundtracks. Each speaker is housed in a sealed enclosure with acoustic damping material to prevent cross talk, while gold plated connectors ensure signal integrity. The set includes mounting hardware and wiring harnesses specific to Mercedes’ electrical systems, ensuring plug and play compatibility with MBUX and Burmester amplifiers. Global variants adapt to regional preferences: more midrange emphasis for vocal heavy genres in Asia, enhanced bass response for North American hip hop, and balanced output for European classical. Whether as a factory fit or aftermarket upgrade, this speaker set transforms the cabin into a 3D soundstage, where every instrument occupies a distinct, tangible space.
