Audi R8 Center Dash Speaker Size
The Audi R8 center dash location accommodates 0.75 inch speakers, 3.5 inch units, and a 3 inch speaker size across the model's production range. Compatible audio types for these positions include tweeter, full-range, and midrange system units. These specifications cover the 2008 to 2018 model years, with a gap in the 2013 and 2016 replacement data.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Tweeter | 0.75 |
| 2018 | Full-Range | 3.5 |
| 2017 | Tweeter | 0.75 |
| 2017 | Full-Range | 3.5 |
| 2015 | Midrange | 3 |
| 2014 | Midrange | 3 |
| 2012 | Midrange | 3 |
| 2011 | Midrange | 3 |
| 2010 | Midrange | 3 |
| 2009 | Midrange | 3 |
| 2008 | Midrange | 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. |
| Midrange | A driver for the middle of the audible range, typically from about 300 Hz to 5,000 Hz, where vocals and most instruments sit. It is often paired with a tweeter and a woofer. |
| 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 center dash location in the Audi R8 sits along the central axis of the dashboard, positioned to project sound toward the listening area between the driver and passenger seats.
- A center dash mounting position typically involves shallow depth constraints, as the dashboard structure limits the available airspace behind the speaker baffle.
- 3-inch midrange drivers occupy the center dash position across the 2008, 2009, 2010, 2011, 2012, 2015 model years of the Audi R8.
- Midrange speakers handle the frequency band roughly between 300 Hz and 5 kHz, covering the core of vocal and instrumental reproduction, which is acoustically significant for a centrally placed speaker in a two-seat cabin.
- A 3-inch cone diameter limits low-frequency extension due to reduced radiating surface area, making the driver dependent on larger woofers elsewhere in the system to cover bass frequencies.
- The 2017 and 2018 Audi R8 center dash accommodates 2 speaker sizes simultaneously: a 0.75-inch tweeter and a 3.5-inch full-range driver.
- The 0.75-inch tweeter reproduces high frequencies, generally from around 3 kHz and above, and at that diameter, the small diaphragm supports wide horizontal dispersion at high frequencies, which affects how treble energy spreads across the cabin from the center dash position.
- Full-range drivers are designed to reproduce a broad frequency spectrum without the need for crossover filtering, though a 3.5-inch full-range unit in the center dash position would have physical limitations in reproducing deep bass.
- The 3.5-inch full-range driver present in 2017 and 2018 specifications is larger than the 3-inch midrange driver used in earlier model years, indicating a dimensional change in the center dash speaker opening between those generations.
- The center dash location places speakers near the windshield base, where reflective surfaces can influence the acoustic behavior of higher-frequency drivers such as tweeters and full-range units.
