Audi S8 C-Pillar Speaker Size
The Audi S8 C-Pillar accommodates a 1 inch speaker size. Tweeter units are the compatible replacement type for the audio system. These specifications cover the 2018 model year chart.

| 2018 | Tweeter | 1 |
Speaker Types
| Type | Description |
|---|---|
| Tweeter | A small driver built for high frequencies, typically from about 2,000 Hz to 20,000 Hz. It adds treble detail and clarity and is usually mounted near ear level or aimed at the listener. |
Additional Notes
- The C-pillar location in the Audi S8 places speakers within the rear structural column of the cabin, a position that directs sound toward rear seat occupants and contributes to the overall stereo soundstage width.
- Mounting at the C-pillar typically involves integration into a trim panel or dedicated pod, where the speaker faces inward toward the passenger compartment at an angle determined by the column's geometry.
- The spatial depth available at a C-pillar is generally shallow, which limits the acceptable speaker size and cone depth - a constraint consistent with the 1-inch diameter specification listed for the 2018 Audi S8 at this location.
- A 1-inch speaker diameter corresponds to a very small cone or dome surface area, which physically restricts the reproduction of low-frequency content due to the limited air displacement such a small driver can generate.
- The tweeter type is a high-frequency driver, generally responsible for reproducing sounds in the upper portion of the audible spectrum, typically from around 2,000 Hz upward, where wavelengths are short enough to be handled by a small diaphragm.
- At the C-pillar, a tweeter placed near ear level for rear passengers supports high-frequency detail and spatial imaging for occupants seated in the rear of the cabin.
- Tweeters exhibit relatively wide horizontal dispersion at high frequencies compared to larger woofers, a characteristic that suits the C-pillar position, where sound must spread across the rear seating area without a direct line-of-sight from every seat.
- The 2018 Audi S8 C-pillar tweeter installation requires a replacement driver with a 1-inch mounting diameter, as the physical cutout and trim integration at that location are sized to that specification.
