Infiniti FX37 Front Door Panel Speaker Size
The Infiniti FX37 front door panel accommodates a 6.5 inch speaker size. Compatible types for the location include midbass and full-range units. The 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 front door panel location in the 2013 Infiniti FX37 accommodates a 6.5-inch speaker cutout, a diameter that fits within the mid-sized woofer category commonly mounted in door cavities.
- Door panel installations place the speaker within an enclosed or semi-enclosed cavity, which affects low-frequency loading and can influence bass output depending on the internal volume behind the cone.
- A 6.5-inch speaker in a front door panel is positioned at a relatively low height relative to the listening position, which has directional implications for mid and high frequencies given the off-axis angle to the listener's ears.
- The 6.5-inch diameter supports a cone surface area sufficient for reproducing lower midrange and upper bass frequencies, generally spanning from around 60 Hz to several kilohertz depending on the driver's design.
- Midbass is a speaker type purpose-built to handle the frequency band between roughly 80 Hz and 500 Hz, prioritizing cone excursion and motor control over high-frequency extension.
- In a front door panel position, a midbass driver reinforces the lower registers of the stereo image, contributing to the sensation of weight and body in vocals and instruments originating at ear level.
- Full-range is a speaker type designed to reproduce a broad frequency spectrum from bass through treble within a single driver, using cone geometry and sometimes a whizzer cone to extend upper-frequency response.
- When a full-range driver occupies the front door panel of the 2013 Infiniti FX37, the single driver handles the entire audible spectrum assigned to that channel without requiring a dedicated crossover network.
- The front door panel mounting surface is typically a rigid molded structure, and the speaker is usually secured via a mounting ring or direct bolt pattern, with the depth of the door cavity determining the maximum acceptable driver depth.
- Door panel installations expose the rear of the speaker basket to the door's internal cavity, meaning road noise, moisture, and structural resonance from the door skin can all interact with the driver's mechanical components.
