Audi RS4 Rear Door Panel Speaker Size
The Audi RS4 rear door panel accommodates a 6.5 inch speaker size. Compatible types for the location include midbass and full-range units. These specifications cover the 2007 to 2008 model range.
| Year | Type | Size (inch) |
|---|---|---|
| 2008 | Midbass / Full-Range | 6.5 |
| 2007 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| 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 rear door panel location in the Audi RS4 accommodates a 6.5 inch speaker across both listed model years.
- A 6.5 inch driver in a rear door panel occupies a mid-sized mounting cavity, typically requiring a cutout depth and diameter that suits standard door card configurations without significant baffle modification.
- Door panel installations position the speaker within the lower portion of the door, meaning the driver fires into the cabin at or below seat level, which influences the directional projection of sound toward the listening area.
- The 6.5 inch cone diameter produces sufficient surface area to move air effectively in the lower midrange and upper bass frequencies, generally covering a range from approximately 60 Hz to 5 kHz depending on the driver's construction.
- A midbass driver in the rear door panel of the Audi RS4 is dedicated to reproducing the lower midrange and upper bass frequencies, typically operating in a crossover system where a separate tweeter handles high frequencies.
- A full-range driver in the rear door panel handles the entire audible spectrum from a single cone, including bass, midrange, and treble, making crossover pairing optional rather than required.
- The rear door panel location places the speaker within an enclosed door cavity, and the internal volume of the door structure functions as an enclosure that affects the low-frequency response and resonance behavior of the installed driver.
- At 6.5 inches, the driver size in the Audi RS4 rear door panel is large enough to deliver meaningful midbass output without requiring a dedicated subwoofer to reinforce that frequency region in a full-range configuration.
