Audi A7 Quattro Rear Door Panel Speaker Size
The Audi A7 Quattro rear door panel accommodates a 0.75 inch speaker size and supports 6.5 inch speakers. Compatible types across both sizes include tweeters and midbass / full-range units. These specifications cover 2012 through 2018.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Tweeter | 0.75 |
| 2018 | Midbass / Full-Range | 6.5 |
| 2017 | Tweeter | 0.75 |
| 2017 | Midbass / Full-Range | 6.5 |
| 2016 | Tweeter | 0.75 |
| 2016 | Midbass / Full-Range | 6.5 |
| 2015 | Tweeter | 0.75 |
| 2015 | Midbass / Full-Range | 6.5 |
| 2014 | Tweeter | 0.75 |
| 2014 | Midbass / Full-Range | 6.5 |
| 2013 | Tweeter | 0.75 |
| 2013 | Midbass / Full-Range | 6.5 |
| 2012 | Tweeter | 0.75 |
| 2012 | Midbass / Full-Range | 6.5 |
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. |
| Midbass | A driver tuned for upper bass and lower midrange, roughly from 80 Hz to 500 Hz. It has longer cone travel than a full-range unit, which supports stronger bass in doors and panels. |
| 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 A7 Quattro rear door panel accommodates 2 distinct speaker sizes simultaneously, indicating a multi-driver mounting configuration within the door panel structure.
- Rear door panels in vehicles of the A7 Quattro's class typically feature a lower cavity mount for a larger woofer-range driver and a separate, elevated or angled mount for a smaller high-frequency driver.
- The 6.5 inch position in the Audi A7 Quattro rear door panel is compatible with midbass and full-range types, meaning the physical cutout and depth of the door cavity are dimensioned to accept a driver of that diameter in either configuration.
- A 6.5 inch driver in a midbass role handles roughly 80 Hz to 500 Hz, reinforcing lower midrange and bass content in the rear cabin zone, where the door panel mounting surface couples the cone's output to the door skin and interior trim for low-frequency projection.
- When a 6.5 inch driver occupies a full-range role in the rear door panel, the frequency responsibility extends upward into the midrange, potentially reaching 4 kHz or beyond, depending on the driver's design and the absence of a dedicated tweeter in the same channel path.
- The 0.75 inch tweeter position in the rear door panel is spatially separate from the 6.5 inch location, reflecting the acoustic need to place a high-frequency driver at a height or angle that reduces path-length interference with the larger driver's output.
- A 0.75 inch tweeter reproduces frequencies typically from around 3 kHz to 20 kHz, where wavelengths are short enough that driver size and placement within the rear door panel directly affect stereo imaging and high-frequency dispersion into the rear passenger area.
- The tweeter type at 0.75 inch is highly directional at upper frequencies, so the angle and facing direction of the rear door panel's tweeter mount influence how treble energy reaches rear-seat passengers.
- The rear door panel location places both driver sizes within the lower half of the door structure, which is a common constraint that affects low-frequency boundary reinforcement from the door skin while introducing potential high-frequency blockage from seat backs or armrests for the tweeter.
- The specifications apply consistently across the 2012 through 2018 model years of the Audi A7 Quattro, indicating that the rear door panel dimensions and mounting configurations remained unchanged across all listed years.
