Infiniti M56 Rear Deck Center Speaker Size
The Infiniti M56 rear deck center location accommodates a 10 inch speaker size, consistent across all available model years. Compatible types for the audio system include subwoofer replacement units. These specifications cover a range from 2011 to 2013.
| Year | Type | Size (inch) |
|---|---|---|
| 2013 | Subwoofer | 10 |
| 2012 | Subwoofer | 10 |
| 2011 | Subwoofer | 10 |
Speaker Types
| Type | Description |
|---|---|
| Subwoofer | A large driver for the lowest bass notes, typically from about 20 Hz to 120 Hz. It is usually installed in a separate enclosure and works alongside the other speakers. |
Additional Notes
- The rear deck center position in the Infiniti M56 accommodates a 10-inch driver across the 2011, 2012, and 2013 model years.
- A 10-inch subwoofer occupies more mounting depth and surface area than smaller drivers, requiring sufficient cavity clearance beneath the rear deck panel to allow proper cone excursion.
- The rear deck center location places the speaker between the passenger cabin and the trunk space, a position that can couple with the trunk volume to reinforce low-frequency output through acoustic loading.
- Subwoofers are dedicated low-frequency transducers, typically reproducing frequencies below 80 to 120 Hz, and are not designed to handle midrange or high-frequency content.
- A 10-inch cone surface area moves a substantial volume of air relative to smaller drivers, which contributes to output capability at bass frequencies in enclosed or semi-enclosed installations.
- The Infiniti M56 rear deck center location is specified exclusively for subwoofer use, meaning the mounting position is acoustically and mechanically suited to a single driver type rather than a full-range or coaxial configuration.
- Rear deck mounting positions are generally oriented to fire upward or rearward into the cabin, and a subwoofer in the center of the rear deck distributes low-frequency energy relatively evenly across the listening area due to the omnidirectional nature of bass frequencies.
- The 10-inch diameter establishes minimum cutout and baffle dimensions that the rear deck structure of the M56 must accommodate, including sufficient baffle width at the center position to maintain structural integrity around the mounting ring.
