Subaru WRX Rear Door Panel Speaker Size
The Subaru WRX 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 2015 model year.
| Year | Type | Size (inch) |
|---|---|---|
| 2015 | 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 2015 Subaru WRX accommodates a 6.5-inch speaker cutout.
- A 6.5-inch driver in a door panel position operates within a cavity bounded by the door's inner and outer metal skins, which affects the available acoustic space behind the cone.
- Rear door panel mounting typically involves a flat or slightly angled baffle surface integrated into the door's inner trim structure, with depth clearance constrained by the door's internal hardware, window mechanisms, and wiring.
- The 6.5-inch diameter is a mid-size format that covers a frequency range roughly spanning 60 Hz to 5 kHz, making rear door placement relevant to lower midrange and upper bass reproduction within the cabin.
- A midbass driver in the rear door panel of the 2015 Subaru WRX focuses on reproducing frequencies in the 80 Hz to 500 Hz range, a range associated with the body and warmth of instruments and vocals, using cone excursion and mass to handle the mechanical demands of lower frequencies.
- Full-range drivers compatible with the rear door panel of the 2015 Subaru WRX are designed to reproduce a wide frequency band from bass through high-frequency content using a single cone, sometimes supplemented by a small integrated tweeter or whizzer cone to extend treble output.
- Rear door panel placement positions the speaker toward the lower half of the listening environment inside the cabin, which influences the directionality of higher-frequency content produced by full-range drivers, as treble is more directional and attenuates more readily off-axis compared to bass frequencies.
- Midbass drivers are typically built with stiffer suspensions and heavier cones relative to full-range designs, which affects the mechanical tolerances required for the mounting depth available in the rear door panel of the 2015 Subaru WRX.
- The rear door panel location places the speaker in proximity to road noise sources such as the wheel well and door seals, a factor relevant to the frequency ranges handled by both midbass and full-range driver types at 6.5 inches.
