Infiniti FX50 Dashboard Speaker Size
The Infiniti FX50 dashboard location accommodates a 1 inch speaker size across all model years. Compatible types for the dashboard position include the tweeter. These specifications cover the 2009 to 2013 model range.
| Year | Type | Size (inch) |
|---|---|---|
| 2013 | Tweeter | 1 |
| 2012 | Tweeter | 1 |
| 2011 | Tweeter | 1 |
| 2010 | Tweeter | 1 |
| 2009 | 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 Infiniti FX50 accommodates a 1-inch speaker opening across the 2009 through 2013 model years.
- Dashboard placement positions speakers at or near windshield level, which is a high mounting point relative to the listening position inside the cabin.
- High mounting positions are acoustically significant for high-frequency reproduction because treble frequencies are highly directional and benefit from being aimed toward the listener's ear level.
- A 1-inch driver diameter is characteristic of tweeter-class speakers, which are physically small to allow the diaphragm to move rapidly enough to reproduce high-frequency content.
- Tweeters handle the upper portion of the audible frequency spectrum, generally covering approximately 2,000 Hz and above, where detail, air, and transient information in audio signals reside.
- The Infiniti FX50 dashboard location is specified as compatible exclusively with the tweeter type, meaning the mounting cavity is sized and positioned for high-frequency drivers rather than mid-range or full-range units.
- A 1-inch tweeter in a dashboard position directs high-frequency energy across the width of the front cabin, which contributes to the perceived width and height of the stereo soundstage for front-seat occupants.
- The small physical footprint of a 1-inch driver is consistent with the shallow and space-constrained cavities typical of dashboard speaker locations, where depth and diameter are limited by the instrument panel structure.
- Because tweeters reproduce frequencies with very short wavelengths, minor differences in mounting angle within the dashboard can affect the directional character of the high-frequency output at the listening position.
