Infiniti QX60 Rear Door Panel Speaker Size
The Infiniti QX60 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 rear door panel location in the Infiniti QX60 positions speakers within the lower portion of the door cavity, where the driver and mounting surface sit at roughly seat-level height relative to passengers.
- Door panel installations typically involve a sealed or semi-sealed cavity behind the speaker basket, with the door's internal structure acting as an enclosure that influences low-frequency output and overall acoustic loading.
- A 6.5 inch driver occupies one of the most common mid-size speaker diameters, with a cone area large enough to move sufficient air for reproducing bass and lower midrange frequencies without requiring the larger enclosure volume that woofers demand.
- In a rear door panel context, a 6.5 inch speaker operates across a frequency range that typically spans from roughly 60 Hz up through several kilohertz, making cone rigidity and surround compliance critical factors for performance at both ends of that range.
- The Infiniti QX60 rear door panel mounting location accepts speakers compatible with the midbass type, which is a driver designed to handle the lower midrange and upper bass frequencies, generally between approximately 80 Hz and 500 Hz.
- Midbass drivers in a rear door position reinforce the low-frequency foundation of audio reproduction in the rear cabin, supplementing any subwoofer or front-stage output directed toward rear-seat passengers.
- The full-range type listed as compatible for the Infiniti QX60 rear door panel describes a single driver intended to reproduce the broadest possible frequency spectrum independently, spanning bass through treble without relying on a crossover network or additional drivers.
- Full-range drivers in rear door panels handle the complete audio signal for that zone, making cone material and spider compliance significant factors in how evenly the driver performs across frequency extremes.
- Door panel speaker cutouts in vehicles of the QX60's class are generally circular with a bolt-circle diameter and mounting depth that must be matched to avoid contact between the speaker magnet assembly and interior door hardware or window mechanisms.
- Mounting depth is a particularly relevant dimension for rear door panel installations because the window regulator and glass channel occupy the inner door cavity, limiting how far a speaker basket and magnet can extend rearward from the mounting surface.
