Infiniti QX80 Rear Door Panel Speaker Size
The Infiniti QX80 rear door panel accommodates a 6.5 inch speaker size across all listed model years. Compatible types for the location include midbass and full-range audio system units. These specifications cover the 2014 to 2017 model year replacement chart 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 Infiniti QX80 rear door panel speaker location is a panel-mounted position integrated into the interior door trim, placing the driver within the rear passenger zone of the cabin.
- Door panel mounting orients the speaker baffle toward the interior seating area, with the cone firing inward across the cabin floor and lower seating level rather than downward or upward.
- A 6.5-inch driver occupies a mid-sized mounting cutout, typically requiring a mounting depth and diameter that fits within the door panel cavity without interference from window mechanisms or door hardware.
- The 6.5-inch cone diameter produces sufficient radiating surface area to move the air volume necessary for mid and upper-bass frequencies, covering roughly 80 Hz to 5 kHz depending on driver design.
- At the rear door panel location, a 6.5-inch driver operates at a distance from front-seated occupants, meaning low-frequency output from the driver contributes to the overall bass foundation perceived throughout the rear seating area.
- The Infiniti QX80 rear door panel compatibility with midbass drivers indicates the mounting location supports drivers tuned specifically to reinforce bass and upper-bass frequencies, typically operating between approximately 80 Hz and 500 Hz.
- A midbass driver uses a stiffer suspension and voice coil optimized for cone excursion in lower frequency ranges, making the type acoustically suited to supplement subwoofer output and anchor the lower portion of the audio spectrum in the rear cabin.
- Full-range driver compatibility at the rear door panel position means a single driver can reproduce a wide frequency span across bass, midrange, and treble without requiring a dedicated crossover network.
- Full-range drivers intended for a 6.5-inch format typically employ a whizzer cone or a highly controlled surround to extend high-frequency dispersion, compensating for the natural high-frequency beaming tendency of larger cone diameters.
- Door panel placement positions the 6.5-inch driver at approximately seat-height for rear passengers, creating a relatively direct acoustic path to rear occupant ear level compared to floor or kick panel locations.
