Infiniti QX60 Front Door Panel Speaker Size
The Infiniti QX60 front door panel accommodates a 6.5 inch speaker size across all listed model years. Compatible types for the location include midbass and full-range units. These specifications cover the 2014 to 2017 model range.
| Year | Type | Size (inch) |
|---|---|---|
| 2017 | Midbass / Full-Range | 6.5 |
| 2016 | Midbass / Full-Range | 6.5 |
| 2015 | Midbass / Full-Range | 6.5 |
| 2014 | 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 front door panel location in the Infiniti QX60 positions speakers within the lower portion of the door, mounted against the interior door panel skin, which places the driver at roughly seat-level height relative to the listening position.
- Door panel mounting subjects speakers to a semi-enclosed rear cavity formed by the door's inner metal shell, which acts as an acoustic chamber influencing bass reinforcement and low-frequency output.
- A 6.5 inch speaker occupies a mid-sized mounting cutout, requiring a compatible depth clearance between the door panel surface and the inner door metal to avoid contact with window mechanisms or structural bracing.
- At 6.5 inches, the cone diameter produces sufficient surface area to move the air volume needed for lower midrange and upper bass frequencies, typically spanning roughly 60 Hz to 5 kHz depending on driver construction.
- The front door panel location places the speaker firing inward and upward toward the cabin occupants, making horizontal dispersion a relevant acoustic factor for stereo imaging at the front stage.
- A midbass driver in the Infiniti QX60 front door panel is designed specifically to reproduce the lower midrange and upper bass bands, typically operating within a crossover system where higher frequencies are handled by a separate tweeter.
- A full-range driver handles a broader frequency span without requiring an active crossover, allowing operation from bass through treble within a single driver, which suits installations without a dedicated tweeter at this location.
- The 6.5 inch format in a door panel environment benefits from the door cavity's natural low-frequency loading, which can extend perceived bass response compared to the same driver mounted in free air.
- Midbass drivers used at the front door panel position contribute the foundational lower-frequency energy of the front soundstage, particularly the weight and body of vocals and lower instrumentation.
- The front door panel location in the QX60 keeps the speaker at a distance from the listener's ear level, which affects time alignment and phase coherence relative to any separately mounted high-frequency driver in the vehicle.
