Audi S4 Center Dash Speaker Size
The Audi S4 center dash location accommodates a 1 inch speaker size, as well as 2.5 and 3 inch units across the model's production span. Compatible speaker types for the center dash include tweeter and midrange replacement units suited for the audio system. These specifications cover a range of years from 2002 to 2018.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Tweeter | 1 |
| 2018 | Midrange | 2.5 |
| 2016 | Midrange | 2.5 |
| 2015 | Midrange | 2.5 |
| 2014 | Midrange | 2.5 |
| 2013 | Midrange | 2.5 |
| 2012 | Midrange | 2.5 |
| 2011 | Midrange | 2.5 |
| 2010 | Midrange | 2.5 |
| 2009 | Midrange | 3 |
| 2008 | Midrange | 3 |
| 2007 | Midrange | 3 |
| 2006 | Midrange | 3 |
| 2005 | Midrange | 3 |
| 2004 | Midrange | 3 |
| 2002 | 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. |
Additional Notes
- The center dash location in the Audi S4 sits at the uppermost central point of the instrument panel, positioning speakers to project sound toward the windshield and into the cabin from a forward, elevated angle relative to seated occupants.
- A center dash mounting position typically involves shallow depth constraints and limited behind-panel volume, which influences the physical size of speakers that can be accommodated without modification.
- The 2.5 inch midrange drivers specified for the Audi S4 center dash occupy a compact diameter suited to the restricted cavity depth common in dashboard installations while still reproducing the mid-frequency band.
- The 3 inch midrange drivers listed for the 2004 through 2009 model years indicate a slightly larger mounting cutout and baffle area was present in the center dash of those earlier Audi S4 generations.
- Midrange speakers handle the frequency band roughly between 300 Hz and 5,000 Hz, which encompasses vocals, instruments, and much of the harmonic content critical to perceived clarity in a listening environment.
- Placement of a midrange driver in the center dash positions the primary vocal and harmonic reproduction at a central point between left and right channels, which is associated with reinforcing phantom center imaging in stereo playback.
- The 1 inch tweeter listed alongside the 2.5 inch midrange for the 2018 Audi S4 center dash indicates a dual-driver configuration at that location for that model year, requiring a more complex mounting arrangement within the same general dash area.
- Tweeters in the 1 inch diameter range reproduce high frequencies, generally from around 2,000 Hz up to 20,000 Hz or beyond, where directional dispersion narrows and placement relative to the listener's ear level has a more pronounced effect on perceived high-frequency presence.
- Mounting a 1 inch tweeter in the center dash of the 2018 Audi S4 places high-frequency reproduction at a central, forward position, which influences the stereo imaging of upper harmonics, transients, and consonant detail from a single shared source point.
- The transition from 3 inch to 2.5 inch midrange sizing beginning with the 2010 model year reflects a change in the physical dimensions of the center dash mounting location between the earlier and later Audi S4 generations covered by these specifications.
- A 2.5 inch midrange cone surface area is smaller than a 3 inch cone, which affects the volume of air the driver displaces and can influence the lower boundary of the frequency range the driver reproduces effectively at that location.
- The center dash location directs sound toward the front of the cabin from a position that is equidistant from left and right seating positions, making speaker placement there well suited to anchoring center-channel or centrally blended audio content.
