Kia K900 Rear Door Panel Speaker Size
The Kia K900 rear door panel accommodates a 6.5 inch speaker size. Compatible types for the location include midbass and full-range audio units. These specifications cover the 2015 to 2017 model range.
| Year | Type | Size (inch) |
|---|---|---|
| 2017 | Midbass / Full-Range | 6.5 |
| 2016 | Midbass / Full-Range | 6.5 |
| 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 speaker location in the Kia K900 accommodates a 6.5-inch driver across the 2015, 2016, and 2017 model years.
- A 6.5-inch speaker occupies a mid-sized mounting diameter, requiring a door panel cavity deep enough to accommodate the basket depth and magnet assembly without interference from the inner door structure or window regulator components.
- The rear door panel position places speakers within the lower portion of the door, angling sound toward the cabin floor and lower passenger seating area rather than directly at ear level.
- At 6.5 inches, the cone surface area is sufficient to move enough air for meaningful low-midrange output, with a typical usable frequency range spanning roughly 60 Hz to 5 kHz depending on the driver's construction.
- The midbass type is designed to handle the lower portion of the midrange and upper bass frequencies, generally operating between approximately 80 Hz and 500 Hz, reinforcing the weight and body of musical instruments and vocals.
- In a rear door panel position, a midbass driver benefits from the acoustic loading provided by the enclosed door cavity, which can support low-frequency extension without requiring a dedicated enclosure.
- The full-range type is designed to reproduce a wide frequency span from bass through treble within a single driver, making solo operation without crossover components a functional configuration.
- A full-range driver installed in the Kia K900 rear door panel would handle the entire audible output for that channel, relying on the cone's pistonic and breakup behavior to cover both low and high frequencies.
- The 6.5-inch diameter at the rear door panel location means the mounting depth and cut-out diameter must be verified against the specific door panel and inner metal structure of the K900 to ensure physical clearance.
- Rear door panel placement typically results in a longer path length to front passengers compared to front door or dash locations, which has implications for stereo imaging and time alignment in multi-speaker systems.
