Audi RS3 Front Door Panel Speaker Size
The Audi RS3 front door panel accommodates a 3.5 inch speaker size and 6.5 inch speakers within the same location. Compatible audio types for the front door panel include midrange and midbass or full-range system units. These specifications cover the 2017 to 2018 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2018 | Midrange | 3.5 |
| 2018 | Midbass / Full-Range | 6.5 |
| 2017 | Midrange | 3.5 |
| 2017 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| 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. |
| 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 front door panel location in the Audi RS3 accommodates 2 distinct speaker sizes simultaneously, indicating a multi-driver configuration within the same door cavity.
- A 3.5 inch driver mounted in the front door panel occupies a smaller, typically shallower cutout, which in a door environment often corresponds to a tweeter pod or mid-dedicated bracket positioned in the upper portion of the panel for improved high-frequency dispersion toward the listening plane.
- The 3.5 inch position in the Audi RS3 front door panel is designated for midrange drivers, meaning the location handles frequencies roughly between 300 Hz and 5 kHz, the range responsible for vocals, upper harmonics, and instrument body definition.
- Midrange drivers at 3.5 inches have a relatively compact cone area, which limits low-frequency extension but supports controlled directivity across the vocal frequency band when mounted at door panel height.
- The 6.5 inch position in the Audi RS3 front door panel supports either midbass or full-range driver types, placing a larger cone within the lower section of the door where enclosure depth and panel rigidity are typically greater.
- A 6.5 inch midbass driver in a front door panel primarily covers frequencies from approximately 60 Hz to 500 Hz, handling the lower-mid and upper-bass content that contributes to perceived warmth and punch in the soundstage.
- A 6.5 inch full-range driver covers a wider frequency band than a dedicated midbass unit, extending into the midrange and sometimes the lower treble, which makes speaker placement within the door panel more acoustically significant due to off-axis coloration at higher frequencies.
- The door panel as a mounting surface introduces cavity resonance behind the driver, particularly relevant for the 6.5 inch position where the enclosed door volume behind the cone can affect bass response and efficiency.
- The 2017 and 2018 Audi RS3 front door panels share identical size and type specifications across both years, indicating consistent cavity dimensions and mounting geometry between those model years.
- In a front door panel installation, the physical separation between the 3.5 inch midrange and the 6.5 inch woofer-range driver creates a spatial crossover condition, where the acoustic output of each driver originates from slightly different positions along the door surface.
