Infiniti M37 Center Dash Speaker Size
The Infiniti M37 center dash location accommodates a 3 inch speaker size across all listed model years. Midrange units represent the compatible audio system replacement types for the center dash. These specifications cover the years 2011 to 2013.
| Year | Type | Size (inch) |
|---|---|---|
| 2013 | Midrange | 3 |
| 2012 | Midrange | 3 |
| 2011 | Midrange | 3 |
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 M37 sits at the top of the dashboard, positioned along the vehicle's central axis to serve as a phantom center channel for front-stage audio imaging.
- A 3-inch driver in the center dash of the Infiniti M37 occupies a shallow, confined cavity typical of upper dashboard placements, where depth and width constraints limit cone excursion and low-frequency extension.
- The center dash mounting position places the speaker at or near ear level for front occupants, which favors the reproduction of frequencies where human speech intelligibility is concentrated.
- A 3-inch cone diameter produces a relatively small radiating surface area, which corresponds to reduced air displacement and a natural acoustic roll-off in the lower frequency registers below approximately 200 Hz.
- The compact diameter of a 3-inch driver supports controlled directivity at mid frequencies, meaning the sound projection remains relatively focused along the listening axis rather than dispersing widely across the cabin.
- Midrange drivers are acoustically designed to reproduce frequencies roughly between 300 Hz and 5 kHz, a band that encompasses fundamental vocal tones, instrument body resonance, and a significant portion of speech formants.
- In a center dash position, a midrange driver functions to anchor vocal and dialogue content to the front-center of the soundstage, a role that depends on precise frequency reproduction rather than high output levels.
- The Infiniti M37 center dash location accommodates a 3-inch midrange driver across the 2011, 2012, and 2013 model years, indicating a consistent enclosure and mounting geometry across all 3 listed model years.
- Midrange drivers in center dash applications typically operate within a crossover network, receiving signal only within their designated passband and excluding the low bass frequencies that a small cone in a shallow dash cavity cannot accurately reproduce.
- The 3-inch form factor in a center dash location is associated with lower moving mass, which supports faster transient response and accurate reproduction of percussive mid-frequency content such as consonant sounds in vocal tracks.
