Kia Forte Rear Door Panel Speaker Size
The Kia Forte rear door panel accommodates a 6.5 inch speaker size and 6.75 inch speakers, with both locations supporting midbass and full-range units. Compatible audio types include midbass and full-range speakers suited for the rear door panel system. These specifications cover a range from 2010 to 2017.
| Year | Type | Size (inch) |
|---|---|---|
| 2017 | Midbass / Full-Range | 6.5 |
| 2016 | Midbass / Full-Range | 6.5 |
| 2015 | Midbass / Full-Range | 6.5 |
| 2014 | Midbass / Full-Range | 6.5 |
| 2013 | Midbass / Full-Range | 6.5 |
| 2012 | Midbass / Full-Range | 6.5 |
| 2011 | Midbass / Full-Range | 6.75 |
| 2011 | Midbass / Full-Range | 6.5 |
| 2010 | 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 Kia Forte positions speakers within the lower portion of the door cavity, placing the driver at a distance from the listening position and at a low angle relative to seated occupants.
- Door panel mounting situates speakers behind a grille or perforated panel surface, which affects high-frequency dispersion and makes full-range performance more dependent on the speaker's off-axis response characteristics.
- The 6.5 inch diameter is the specified size across the 2010 through 2017 model years for the rear door panel location, with a cone area suited to reproducing low-midrange and bass frequencies with adequate displacement.
- A 6.5 inch driver in a door cavity benefits from the enclosure-like volume behind the panel, which reinforces low-frequency output, particularly in the 60 Hz to 250 Hz range where midbass energy is concentrated.
- The 2011 Kia Forte rear door panel lists both 6.75 inch and 6.5 inch as compatible sizes, indicating a fitment variation within that model year where the mounting cutout may accommodate either diameter.
- The 6.75 inch diameter listed for the 2011 model year is marginally larger than 6.5 inch, with a slightly greater cone area that can contribute to modestly increased low-frequency displacement under equivalent power input.
- Midbass speakers are designed to handle the frequency band roughly between 80 Hz and 500 Hz, focusing on the lower midrange and upper bass region rather than extending into treble frequencies.
- In a rear door panel location, a midbass driver reinforces the low-end body of vocals and instruments, a role that aligns with the rear position's contribution to spatial fullness in a cabin environment.
- Full-range speakers are designed to reproduce a wide portion of the audible spectrum from bass through treble within a single driver, relying on cone geometry and surround materials to manage frequency response across that span.
- When a full-range driver is mounted in the rear door panel position, the low-angle placement and panel obstruction tend to limit the effectiveness of high-frequency reproduction, which is inherently directional above approximately 2 kHz.
- The door panel mounting depth available in the Forte's rear door is a physical constraint that determines which speaker basket profiles are mechanically compatible with the 6.5 inch or 6.75 inch cutout dimensions.
