Infiniti G37 Rear Side Panel Speaker Size
The Infiniti G37 rear side panel accommodates a 3.5 inch speaker size across all listed model years. Midrange units are the compatible speaker type for the location. The specifications cover a range of years from 2008 to 2013.
| Year | Type | Size (inch) |
|---|---|---|
| 2013 | Midrange | 3.5 |
| 2012 | Midrange | 3.5 |
| 2011 | Midrange | 3.5 |
| 2010 | Midrange | 3.5 |
| 2009 | Midrange | 3.5 |
| 2008 | Midrange | 3.5 |
Speaker Types
| Type | Description |
|---|---|
| Midrange | A driver for the middle of the audible range, typically from about 300 Hz to 5,000 Hz, where vocals and most instruments sit. It is often paired with a tweeter and a woofer. |
Additional Notes
- The rear side panel location in the Infiniti G37 is a laterally mounted position within the cabin's rear quarter, typically recessed into the interior trim panel behind the rear passenger seating area.
- A 3.5-inch driver occupies a compact mounting footprint, which suits the limited depth and surface area commonly available within a rear side panel cavity.
- The shallow mounting depth typical of rear side panel locations constrains the available excursion space for a driver, making a small-diameter cone like a 3.5-inch unit a practical fit for that enclosure geometry.
- In the Infiniti G37 rear side panel, the 3.5-inch cone diameter limits low-frequency extension, as smaller diaphragms move less air volume and are better suited to upper-spectrum reproduction than to bass frequencies.
- A midrange driver is designed to reproduce frequencies roughly between 300 Hz and 5,000 Hz, covering the band most critical to vocal intelligibility and instrumental presence in an audio system.
- Placement in the rear side panel positions a midrange driver at a lateral angle relative to front passengers, which affects the directional arrival of midrange frequencies from the rear of the cabin.
- Midrange drivers are typically not crossed over to handle deep bass or high treble content, functioning instead as a band-specific transducer within a multi-driver system.
- The 3.5-inch form factor in a midrange application at the Infiniti G37 rear side panel aligns with a role of filling spatial gaps in midband coverage rather than anchoring low-end or high-frequency reproduction.
- Across all model years listed, 2008 through 2013, the mounting cutout diameter and compatible driver type remain consistent, indicating a fixed cavity specification for the rear side panel throughout the G37's production run in those years.
- The rear side panel location is distinct from rear deck or door placements in that side panel drivers typically face inward toward the cabin rather than upward or outward, affecting the dispersion pattern of mid-frequency sound waves within the vehicle interior.
