Scion iM Rear Door Panel Speaker Size
The Scion iM rear door panel accommodates a 6.5 inch speaker size. Compatible types for the location include midbass and full-range audio system units. These specifications cover the 2016 model year.
| Year | Type | Size (inch) |
|---|---|---|
| 2016 | 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 2016 Scion iM accommodates a 6.5-inch speaker mounting configuration.
- Door panel speaker locations are typically recessed within a molded cavity in the inner door skin, with mounting depth and baffle clearance determined by the door's internal structure and window mechanism.
- A 6.5-inch driver in a rear door panel position operates within a partially enclosed air volume formed by the door cavity, which influences low-frequency loading and overall output characteristics.
- The 6.5-inch diameter is a mid-sized cone format that balances low-frequency extension with midrange reproduction, making rear door placement acoustically relevant for filling the cabin's lower frequency field.
- Midbass drivers in the 6.5-inch format at the rear door panel are optimized to handle frequencies roughly between 80 Hz and 500 Hz, contributing foundational low-midrange energy to the listening environment.
- Full-range drivers in the 6.5-inch format at the rear door panel reproduce a broader frequency spectrum - typically from the upper bass range through the midrange and into the lower treble - without requiring a dedicated crossover network.
- The rear door panel position places the speaker at a lower height relative to the listener's ear level, which affects the directional perception of midrange and upper frequencies produced by full-range configurations.
- The Scion iM rear door panel's compatibility with both midbass and full-range types at 6.5 inches indicates the mounting cutout and depth clearance are shared across both driver configurations.
- In a rear door installation, midbass drivers are often crossed over at the high end to a separate tweeter mounted elsewhere in the cabin, as the rear door position at lower height is less suited for high-frequency dispersion toward seated listeners.
- Full-range drivers at the rear door panel position handle treble frequencies with reduced directional effectiveness compared to a higher or angled mounting point, due to the low placement and the listener's seated ear height.
