Infiniti Q70L Rear Door Panel Speaker Size
The Infiniti Q70L rear door panel accommodates a 6.5 inch speaker size and 6x9 inch speakers, supporting both unique sizes across the model's production span. Compatible speaker types include midbass and full-range units. These specifications cover the 2015 to 2017 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2017 | Midbass / Full-Range | 6.5 |
| 2016 | Midbass / Full-Range | 6.5 |
| 2015 | Full-Range | 6x9 |
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 places speakers within an enclosure formed by the door's internal cavity, where the speaker fires inward toward the cabin passenger area at rear seating positions.
- A 6.5 inch driver in the rear door panel occupies a mid-sized mounting diameter, requiring a cutout and depth clearance compatible with the door's inner structure while remaining manageable within the limited depth typical of door cavities.
- A 6x9 inch driver presents a larger, oval footprint that demands a wider and longer cutout than a 6.5 inch round driver, meaning the 2015 Infiniti Q70L rear door panel carries a mounting recess dimensioned specifically to accommodate the elongated 6x9 inch frame.
- The 6x9 inch format's greater cone surface area relative to a 6.5 inch driver allows for higher displacement, which is relevant to reproducing lower frequencies at the rear door panel position.
- A midbass driver is designed to handle the frequency range roughly between 80 Hz and 500 Hz, concentrating on lower midrange and upper bass reproduction without extending into high-frequency content.
- In the rear door panel location, a midbass driver would typically function as part of a multi-component system, where a separate tweeter handles high frequencies that the midbass driver does not reproduce.
- A full-range driver is designed to reproduce a wide frequency span, from bass through treble, within a single driver unit, making it capable of standalone operation at the rear door panel without requiring an additional tweeter.
- The 6.5 inch drivers listed for 2016 and 2017 are compatible with both midbass and full-range types, meaning the rear door panel mounting location in those model years accommodates either a component or coaxial installation approach.
- The 2015 model year rear door panel is listed exclusively with the full-range type in the 6x9 inch size, indicating the mounting configuration for that year is paired only with speakers designed for broadband frequency reproduction.
- Rear door panel speakers generally exhibit a wider, more diffuse dispersion pattern compared to front-stage speakers, as the rear door position angles sound energy toward the center of the cabin rather than directly toward listeners.
