Infiniti G37 Center Dash Speaker Size
The Infiniti G37 center dash location accommodates a 4 inch speaker size across all model years. Midrange units represent the compatible speaker type for the audio system. The specifications cover a range from 2008 to 2013.
| Year | Type | Size (inch) |
|---|---|---|
| 2013 | Midrange | 4 |
| 2012 | Midrange | 4 |
| 2011 | Midrange | 4 |
| 2010 | Midrange | 4 |
| 2009 | Midrange | 4 |
| 2008 | Midrange | 4 |
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 center dash location in the Infiniti G37 sits along the central axis of the dashboard, positioning the speaker equidistant from the left and right seating positions to serve the full width of the cabin.
- A center dash mounting position places the speaker at or near ear level for front passengers, which is acoustically significant for frequencies that are highly directional and perceptible to localization by the human ear.
- The 4-inch diameter specified for the Infiniti G37 center dash reflects the spatial constraints typical of a center dash cavity, where depth and width are limited by dashboard structure, HVAC components, and instrument cluster housing.
- A 4-inch driver operates within a relatively compact cone area, which limits low-frequency excursion but supports accurate reproduction in the midrange band without requiring significant enclosure depth behind the mounting surface.
- Midrange speakers are designed to handle frequencies approximately between 500 Hz and 5,000 Hz, the range that contains the core of human speech, vocals, and a large portion of musical instrument fundamentals and harmonics.
- The midrange type specified for the Infiniti G37 center dash is a dedicated full-excursion driver built without the crossover divisions of a tweeter or woofer, intended to reproduce the middle portion of the audio spectrum with clarity and minimal distortion.
- The center dash placement reinforces the midrange driver's role in imaging, as centering the primary vocal and instrumental frequencies at the front of the cabin creates a focused soundstage for front-seat listeners.
- A 4-inch midrange at the center dash location complements speakers at the door or rear deck positions by handling frequencies that smaller tweeters cannot reproduce at sufficient volume and that larger woofers reproduce with less precision and directionality.
- The consistent 4-inch midrange specification across the 2008 through 2013 model years indicates a stable mounting cavity dimension throughout the G37 generation, with no change in the physical cutout or depth requirements across those years.
