Audi TT Quattro Center Dash Speaker Size
The Audi TT Quattro center dash accommodates a 4 inch speaker size and 2 inch speakers, depending on the model year. Compatible audio types include midrange units and tweeters, each corresponding to the respective size. These specifications cover a range of years from 2000 to 2018.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Midrange | 4 |
| 2017 | Midrange | 4 |
| 2016 | Midrange | 4 |
| 2015 | Midrange | 4 |
| 2006 | Tweeter | 2 |
| 2005 | Tweeter | 2 |
| 2004 | Tweeter | 2 |
| 2003 | Tweeter | 2 |
| 2002 | Tweeter | 2 |
| 2001 | Tweeter | 2 |
| 2000 | Tweeter | 2 |
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 TT Quattro places a speaker at the top-center of the instrument panel, a position that sits near the windshield and at ear level for front occupants, which influences both dispersion angle and high-frequency reflection behavior.
- A center dash mounting position is generally shallow in depth and constrained in diameter, requiring speakers with compact enclosure profiles and limited excursion demands.
- The 4-inch driver size specified for 2015 through 2018 model years occupies more cone area than smaller dash-mounted units, allowing greater acoustic output and extended low-midrange reproduction within the center dash cavity.
- Midrange drivers are designed to reproduce frequencies roughly between 300 Hz and 5,000 Hz, covering the vocal and instrument presence range that contributes heavily to perceived audio clarity at the listening position.
- A 4-inch midrange in the center dash position of the Audi TT Quattro is oriented toward the front seating area, placing midrange frequencies along a direct path toward the listener without strong reflective interference from side panels or doors.
- The 2-inch driver size specified for model years 2000 through 2006 reflects a smaller mounting cutout and shallower rear clearance in the center dash, consistent with the physical constraints of that generation's instrument panel construction.
- Tweeter drivers are engineered to reproduce high frequencies, typically from around 2,000 Hz to 20,000 Hz, where wavelengths are short enough that even small cone diameters can radiate sound efficiently.
- The Audi TT Quattro center dash location for 2000 through 2006 uses a 2-inch tweeter, a size whose narrow dispersion at high frequencies is well-suited to a center-mounted position that projects directly toward the listening zone.
- At 2 inches, the tweeter cone has a high resonant frequency threshold, meaning the driver is acoustically unsuited to reproduce midrange content without distortion, which aligns with the exclusive tweeter-type designation in the specifications for those years.
- The center dash position sits away from door-panel vibration sources and structural flex points, which is acoustically relevant for tweeter and midrange drivers that are sensitive to unwanted mechanical resonance.
