| 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 A8 Quattro positions speakers within the rear cabin structure, placing audio output at an elevated angle toward rear passengers.
- A C-pillar mounting point is structurally integrated into the vehicle's rear body frame, which typically results in a fixed, non-adjustable speaker orientation determined by the pillar's angle and trim panel cutout.
- The spatial depth available within a C-pillar cavity is generally shallow, a characteristic that favors compact driver designs with minimal rear clearance requirements.
- A 1-inch driver diameter corresponds to a small cone or dome surface area, which is physically suited to the constrained dimensions typical of C-pillar trim cavities.
- The 1-inch size in the Audi A8 Quattro C-pillar is compatible exclusively with the tweeter type, meaning the driver at this location operates in the high-frequency portion of the audio spectrum.
- Tweeters reproduce high-frequency sounds, generally operating in the range above approximately 2,000 Hz, covering audio content such as upper harmonics and transient detail.
- The small diaphragm mass of a 1-inch tweeter allows rapid movement in response to high-frequency signals, which is a physical requirement for accurate reproduction at those frequencies.
- High-frequency sound waves are directional, meaning the placement of a tweeter in the C-pillar creates a localized dispersion pattern aimed at the rear seating area rather than the full cabin.
- Because low-frequency reproduction requires larger diaphragm excursion and driver size, the 1-inch tweeter at the C-pillar position is acoustically limited to the upper frequency range by design.
