Subaru Impreza Rear Speaker Size
The Subaru Impreza rear location accommodates a 6.5 inch speaker size. Compatible types for the rear include midbass and full-range audio system units. These specifications cover the 2017 model year.
| Year | Type | Size (inch) |
|---|---|---|
| 2017 | 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 speaker location in the 2017 Subaru Impreza accommodates a 6.5-inch driver, a diameter that fits within a mid-sized mounting cavity typically found in rear door panels or rear deck positions.
- A 6.5-inch speaker requires a sufficient mounting depth behind the baffle surface, meaning the rear installation point must have adequate clearance behind the panel to avoid contact with structural elements or window mechanisms.
- The 6.5-inch diameter produces a cone area large enough to move meaningful air volume at lower frequencies, making rear placement effective for filling the cabin with mid and upper-bass energy.
- Midbass drivers in a 6.5-inch format at the rear position handle the frequency range roughly between 80 Hz and 500 Hz, reinforcing the lower-midrange and upper-bass content that contributes to perceived warmth and body in the listening environment.
- A midbass driver is designed without a tweeter element, concentrating its mechanical and acoustic behavior on low-to-mid frequencies, which suits rear placement where high-frequency directionality is less critical than bass support.
- Full-range drivers cover a broader spectrum than dedicated midbass units, typically extending from around 60 Hz up to 20 kHz, allowing a single cone or coaxial assembly to reproduce multiple frequency bands from the rear location.
- Full-range speakers installed at the rear often use a secondary tweeter element mounted coaxially or on a separate pole, enabling high-frequency reproduction without requiring a dedicated tweeter installation at that location.
- The 2017 Subaru Impreza rear speaker position, as a 6.5-inch cutout, sets the maximum outer frame diameter a replacement driver can measure before the mounting flange exceeds the factory opening.
- Mounting depth is a separate spatial constraint from diameter; a 6.5-inch driver with an unusually deep basket may not clear the interior structure behind the rear panel even when the diameter fits the cutout.
- The compatibility of both midbass and full-range types with the 6.5-inch rear opening indicates the factory mounting configuration accepts either a dedicated low-mid driver or a multi-way driver assembly within the same physical space.
