Infiniti EX37 Rear Door Panel Speaker Size
The Infiniti EX37 rear door panel accommodates a 6.5 inch speaker size. Compatible types for the location include midbass and full-range audio 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 rear door panel location in the 2013 Infiniti EX37 accommodates a 6.5-inch speaker, a diameter that fits within a standard door cavity while supporting a cone area large enough to move sufficient air for lower-frequency reproduction.
- Door panel installations are typically surface-mounted or basket-mounted against a flat or contoured panel, with the speaker depth (mounting depth) being a critical dimension to avoid interference with door hardware, window mechanisms, or inner door skin.
- The rear door panel position places speakers in a low and rearward orientation relative to the listening area, which influences the perceived directionality and soundstage contribution of any speaker installed in the location.
- A 6.5-inch driver in a rear door panel produces output primarily in the lower midrange and upper bass frequencies, roughly spanning 60 Hz to 5 kHz depending on the specific driver's design, making the mounting cavity's internal volume and any rear-chamber sealing relevant to low-frequency extension.
- The midbass type, listed as compatible for the 2013 Infiniti EX37 rear door panel, is a driver designed to handle frequencies concentrated in the bass and lower midrange bands, typically crossed over from a separate tweeter or midrange driver handling higher frequencies.
- A midbass driver in the rear door panel position reinforces low-frequency body and warmth in the cabin, as the rear doors are physically distanced from the primary listening position, allowing bass wavelengths-which are largely omnidirectional-to propagate throughout the interior effectively.
- The full-range type, also listed as compatible, covers a broader frequency spectrum within a single driver, spanning bass through treble, which makes the speaker's off-axis high-frequency performance relevant given the low and angled mounting position of a rear door panel.
- The 6.5-inch cone diameter supports the mechanical excursion needed to reproduce midbass frequencies at adequate volume levels, while also maintaining enough pistonic rigidity for the midrange frequencies relevant to full-range operation.
- Mounting depth clearance behind the rear door panel of the EX37 is a fixed spatial constraint that determines whether a given 6.5-inch driver's basket and magnet assembly will physically fit without contacting the door's inner metal structure.
- The rear door panel location is subject to vibrational interference from road noise and door panel resonance, which can affect the acoustic output of both midbass and full-range drivers mounted in the position.
