Scion iA Rear Door Panel Speaker Size
The Scion iA 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 places speakers within the lower portion of the door structure, where the speaker fires into the cabin from a position near seat level.
- At seat level, rear door speakers typically interact with interior surfaces at close range, influencing how low- and mid-frequency energy disperses throughout the cabin.
- A 6.5-inch driver in the rear door panel of the Scion iA occupies a mid-sized mounting footprint, requiring a cutout and depth clearance consistent with standard aftermarket and OEM 6.5-inch configurations.
- The 6.5-inch diameter supports cone surface area sufficient to move air for lower midrange and upper bass frequencies, generally covering a range from approximately 60 Hz to 5 kHz depending on driver design.
- In a rear door panel position, a 6.5-inch driver benefits from the door cavity acting as an enclosure, which can reinforce bass output without a separate sealed or ported box.
- The midbass type is a driver designed to handle frequencies in the lower midrange and upper bass bands, typically between roughly 80 Hz and 500 Hz, without extending fully into high-frequency reproduction.
- A midbass driver installed in the rear door panel of the 2016 Scion iA would operate as part of a multi-speaker system, relying on a separate tweeter to cover upper frequencies the midbass driver does not reproduce.
- The full-range type is a single driver designed to reproduce a wide frequency spectrum, from bass through treble, without requiring a separate high-frequency driver in the same location.
- A full-range driver in the rear door panel position handles the entire audible output for that zone from a single cone, which is a characteristic of the full-range type rather than a function of the installation location alone.
- Door panel speaker locations are subject to depth restrictions imposed by window regulator mechanisms, door hardware, and the panel skin, all of which constrain the mounting depth available for the installed driver.
