Audi S8 Dashboard Speaker Size
The Audi S8 dashboard accommodates 1 inch speaker size and 3 inch units across the model's production runs. Compatible types for the 1 inch units include tweeters, while the 3 inch units support full-range speakers. These specifications cover the years 2007 through 2018.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Tweeter | 1 |
| 2017 | Tweeter | 1 |
| 2016 | Tweeter | 1 |
| 2015 | Tweeter | 1 |
| 2014 | Tweeter | 1 |
| 2013 | Tweeter | 1 |
| 2009 | Full-Range | 3 |
| 2008 | Full-Range | 3 |
| 2007 | Full-Range | 3 |
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. |
| Full-Range | A single driver that reproduces bass through treble without a separate crossover network. It is the simplest replacement option and is common in factory audio systems. |
Additional Notes
- The Audi S8 dashboard speaker location accommodates 2 distinct sizes across the listed model years: 1 inch and 3 inch.
- Dashboard installations are typically shallow-mount positions with limited depth clearance, placing acoustic output near the windshield and forward of the listening position, which shapes the perceived soundstage directionality toward the front of the cabin.
- The 1-inch diameter is a standard tweeter form factor, suited to the spatial constraints of dashboard cavities where larger driver frames would not fit within the available cutout dimensions.
- Tweeters reproduce high-frequency content, generally from around 2,000 Hz upward, and placement in the dashboard of the Audi S8 positions high-frequency output at approximately ear level for front-seat occupants, supporting a coherent front soundstage.
- At 1 inch, the tweeter diaphragm is small enough to maintain controlled high-frequency dispersion, which is relevant in a dashboard location where the driver sits in close proximity to the speaker.
- The 3-inch full-range driver occupies the dashboard position in the 2007, 2008, and 2009 Audi S8 model years, a size that can operate across a wider frequency band within a compact mounting footprint.
- Full-range drivers are designed to reproduce low, mid, and high frequencies from a single cone, making the 3-inch unit in the S8 dashboard responsible for the entire audible spectrum at that location rather than a divided crossover role.
- A 3-inch cone driver in a dashboard position operates with limited low-frequency extension due to the small cone area and the typically shallow enclosure volume available behind dashboard panels, which constrains bass output at that location.
- The transition from 3-inch full-range drivers in 2007-2009 to 1-inch tweeters in 2013-2018 reflects a change in the acoustic role assigned to the Audi S8 dashboard location across those model generations.
- The 1-inch tweeter in the 2013-2018 dashboard position of the Audi S8 operates as a high-frequency-only component, indicating a multi-speaker system configuration where other locations in the vehicle handle mid and low frequencies.
