- The 2017 Audi A4 features a multi-driver speaker configuration with dedicated tweeters positioned in four separate locations throughout the cabin, suggesting a factory design oriented toward spatial sound distribution rather than consolidated component speakers.
- Tweeter locations include the A-pillar, center dash, dashboard, and rear door panels, all utilizing 1-inch drivers that handle high-frequency reproduction across the listening environment.
- Midrange frequencies are addressed through both a 2.5-inch center dash driver and 3.5-inch front door panel drivers, indicating a three-way separation in the front soundstage that may benefit from component speaker upgrades maintaining similar size specifications.
- The 6.5-inch front and rear door panel positions accept both midbass and full-range speaker types, providing flexibility for either two-way component system installations or coaxial replacements depending on the desired level of sound refinement.
- Rear soundstage duties fall to 6.5-inch door panel drivers for mid-frequencies, 3.5-inch rear deck lid full-range speakers, and an 8-inch woofer also mounted in the rear deck lid, creating a bass-reinforced configuration in the aft section of the cabin.
- The presence of dedicated woofer and separate tweeter positions suggests that aftermarket component systems matching these sizes could potentially offer more substantial sonic improvements compared to coaxial speaker swaps.
- Priority for replacement might logically fall to the larger 6.5-inch and 8-inch drivers, as these handle the majority of audible frequency content and typically show more pronounced degradation over time than smaller tweeters.
- The dual full-range capability of the 6.5-inch positions offers installation versatility, though component speakers would likely provide better integration with the existing tweeter network already present in multiple locations.
