Infiniti FX50 Cargo Area Speaker Size
The Infiniti FX50 cargo area accommodates a 5.25 inch speaker size across all listed model years. Compatible speaker types for the location include midbass and full-range units. The specifications cover a range of years from 2009 to 2013.
| Year | Type | Size (inch) |
|---|---|---|
| 2013 | Midbass / Full-Range | 5.25 |
| 2012 | Midbass / Full-Range | 5.25 |
| 2011 | Midbass / Full-Range | 5.25 |
| 2010 | Midbass / Full-Range | 5.25 |
| 2009 | Midbass / Full-Range | 5.25 |
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 cargo area of the Infiniti FX50 accommodates a 5.25 inch speaker across all listed model years from 2009 through 2013.
- A 5.25 inch driver occupies a mid-sized mounting footprint, requiring a cutout diameter and mounting depth that fall between compact 4 inch units and larger 6.5 inch woofers, making physical fitment in a cargo panel a moderately space-conscious installation.
- Cargo area speaker locations are typically positioned low in the vehicle, near the rear load floor or side trim panels, which places the driver at a distance from front listeners and at an angle that affects rear soundstage contribution.
- At a 5.25 inch cone diameter, a speaker produces meaningful output in the upper bass and lower midrange frequencies, roughly covering the 80 Hz to 5,000 Hz range depending on the driver's specific design.
- The midbass type listed as compatible for the Infiniti FX50 cargo area is a driver optimized for the lower portion of the midrange and the upper bass region, handling frequencies where punch and body in vocals and instruments are most prominent.
- A midbass driver in a cargo location reinforces rear low-midrange output, which can support the overall bass presence perceived from the listening position in the front cabin.
- The full-range type listed as compatible is a single driver designed to reproduce a broad span of frequencies on its own, typically from low bass through high treble, often incorporating a whizzer cone or similar mechanism to extend high-frequency output.
- A 5.25 inch full-range driver installed in the cargo area of the FX50 would handle the entire audio spectrum from a single mounting point, without requiring a separate tweeter or woofer at that location.
- The cargo area mounting environment tends to be acoustically isolated from the main cabin by rear seat structures, which influences how sound from a 5.25 inch driver at that location reaches passengers seated forward.
- Both compatible types share the same 5.25 inch mounting requirement, meaning the physical installation space in the FX50 cargo area does not change between a midbass or full-range driver selection.
