Infiniti FX37 Rear Door Panel Speaker Size
The Infiniti FX37 rear door panel accommodates a 6.5 inch speaker size. Compatible types for the location include midbass and full-range audio units. These specifications cover the 2013 model year.
| Year | Type | Size (inch) |
|---|---|---|
| 2013 | 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 2013 Infiniti FX37 accommodates a 6.5-inch speaker, a diameter that positions the driver within the mid-size woofer class.
- A 6.5-inch driver in a door panel operates within an enclosure formed by the door cavity itself, where the internal volume and any deadening material affect low-frequency output and resonance behavior.
- Door panel installations place the speaker in a baffle that is angled toward the cabin floor and lower seating area, which influences the dispersion pattern and how sound reaches the listening position.
- At 6.5 inches, a driver in the rear door panel of the Infiniti FX37 rear door panel is physically suited to reproduce frequencies roughly spanning from the upper bass region through the lower midrange, generally from around 60 Hz to 5 kHz depending on cone material and surround design.
- A midbass driver, as one of the compatible types for the 2013 Infiniti FX37 rear door, is designed to focus on the bass and lower midrange frequencies, typically operating in a crossover system where higher frequencies are handled by a separate tweeter.
- Full-range drivers, the second compatible type listed, are constructed to reproduce a wider frequency spectrum from a single cone, making them a functional replacement in door locations without an active crossover network.
- The rear door panel position places the speaker at a lower height in the cabin relative to the front stage, a characteristic that affects the perceived soundstage and stereo imaging for rear-seat passengers.
- Door panel mounting subjects the speaker to vibrations transmitted through the vehicle body structure, making the mechanical rigidity of the driver's basket and cone material relevant to long-term performance in the 2013 FX37 rear door application.
- A 6.5-inch midbass driver in a rear door relies on the door cavity as a passive enclosure, and the acoustic properties of that cavity, including volume and sealing, influence the driver's effective low-frequency extension.
- Full-range compatibility at 6.5 inches in the rear door panel indicates the mounting depth and cutout dimensions of the location can accept drivers designed with wider frequency response cones, which are typically built with a dust cap and surround geometry optimized for extended high-frequency reach.
