Scion iA Dashboard Speaker Size
The Scion iA dashboard accommodates a 1 inch speaker size. Compatible types for the location include tweeter units. These specifications cover the 2016 model year.
| Year | Type | Size (inch) |
|---|---|---|
| 2016 | Tweeter | 1 |
Speaker Types
| Type | Description |
|---|---|
| Tweeter | A small driver built for high frequencies, typically from about 2,000 Hz to 20,000 Hz. It adds treble detail and clarity and is usually mounted near ear level or aimed at the listener. |
Additional Notes
- The dashboard location in the Scion iA positions speakers at the forward edge of the cabin, near the base of the windshield, placing sound sources close to ear level for front-seat occupants.
- A dashboard mounting surface is typically shallow in depth, which favors compact speaker designs with minimal rear clearance requirements.
- The 1-inch diameter specified for the 2016 Scion iA dashboard is consistent with the tight spatial constraints found in dashboard cavities, where larger driver frames would conflict with the underlying structural and HVAC components.
- A 1-inch driver in a dashboard position covers the high-frequency range, generally from around 2,000 Hz to 20,000 Hz, which includes the upper harmonics, consonants in speech, and fine transient detail in audio reproduction.
- The tweeter type listed as compatible with the 2016 Scion iA dashboard is a dedicated high-frequency transducer, designed with a small, lightweight diaphragm that moves rapidly to reproduce short, fast sound waves without the mass-related distortion that would affect a larger driver at those frequencies.
- Tweeters in a dashboard position benefit from the forward-facing placement, as high-frequency sound is highly directional and loses presence when aimed away from the listener.
- The proximity of a dashboard tweeter to the windshield glass can introduce acoustic reflection, where high-frequency waves bounce off the glass surface and interact with the direct sound reaching the listener.
- A 1-inch tweeter crossing over from a woofer or midrange driver in another location handles only the uppermost frequency band, so the dashboard enclosure does not need to support low-frequency excursion or significant air volume behind the driver.
