Infiniti M56 Center Dash Speaker Size
The Infiniti M56 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. The 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 M56 sits along the vehicle's axis of symmetry, positioning a speaker at the closest fixed point to both front occupants for centered, forward-facing sound projection.
- A speaker mounted at the center dash occupies a shallow, acoustically reflective cavity, which influences how sound interacts with the dashboard surface and the windshield above.
- The 3-inch diameter specified for the Infiniti M56 center dash represents a compact cone area, which limits low-frequency displacement but allows the driver and front passenger to receive tightly focused midband audio from a single central source.
- At 3 inches, the cone excursion required to produce bass frequencies would exceed the physical capability of a driver of that size, making the midrange type the acoustically appropriate match for the center dash position in the M56.
- Midrange speakers are designed to reproduce frequencies approximately between 300 Hz and 5,000 Hz, covering the core intelligibility band where vocals, dialogue, and the fundamental tones of most instruments are concentrated.
- The center dash placement of a midrange driver in the Infiniti M56 aligns the speaker's directional output toward the listening plane of the front occupants, supporting phantom center imaging in a multi-speaker audio system.
- A 3-inch midrange driver at the center dash carries a relatively light moving mass, which contributes to transient accuracy and detail reproduction in the vocal frequency range.
- The center dash position is generally distant from subwoofer enclosures and separated from door-mounted woofers, assigning the midrange driver responsibility for frequencies that neither low-frequency drivers nor tweeters handle optimally.
- Midrange drivers, unlike full-range speakers, are typically crossed over electronically within the head unit or amplifier, meaning the center dash unit in the M56 receives a bandpass signal rather than the full audio spectrum.
- The 3-inch form factor is consistent with the spatial constraints of a center dash pod or grille opening, where dashboard depth and width restrict the use of larger-diameter drivers.
