Nissan Murano D-Pillar Speaker Size
The Nissan Murano D-Pillar accommodates a 3 inch speaker size in the designated location. Midrange units are the compatible type for audio system replacement in that position. These specifications cover the 2009 to 2017 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2017 | Midrange | 3 |
| 2016 | Midrange | 3 |
| 2015 | Midrange | 3 |
| 2014 | Midrange | 3 |
| 2013 | Midrange | 3 |
| 2012 | Midrange | 3 |
| 2011 | Midrange | 3 |
| 2010 | Midrange | 3 |
| 2009 | 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 D-pillar is the rearmost structural pillar in an SUV body, positioned at the far corners of the cargo or rear passenger area, placing speakers in an elevated and rearward-facing orientation relative to the cabin.
- Mounting at the D-pillar situates speakers at significant distance from front-seat occupants, which affects the spatial imaging and rear soundstage contribution of any driver installed there.
- A 3-inch speaker diameter is a compact form factor, consistent with the constrained enclosure depth and surface area typically available within pillar cavities, where structural reinforcement and trim panels limit available space.
- The small cone area of a 3-inch driver produces limited low-frequency output, as larger cone surface and longer excursion are generally required to move sufficient air for bass reproduction.
- The Nissan Murano D-pillar's specified 3-inch size constrains the compatible driver to one that handles focused mid-frequency content rather than extended low or high-frequency ranges.
- Midrange speakers are designed to reproduce the frequency band approximately between 500 Hz and 5 kHz, which covers the core range of human speech, vocals, and many acoustic instruments.
- A midrange driver at the D-pillar contributes rear ambient fill within the vocal and presence frequencies, supplementing front speakers in the overall cabin soundfield.
- A 3-inch midrange at the D-pillar location operates without the need for deep enclosure volume, as the midrange frequency band requires less air compliance behind the cone compared to woofers of larger sizes.
- Midrange drivers are typically not designed to handle the high-excursion demands of bass reproduction, making the compatibility pairing of midrange with the 3-inch size in a pillar cavity acoustically appropriate.
- The D-pillar position places the speaker toward the ceiling level of the rear cabin, which influences the perceived dispersion pattern and height of the rear acoustic image.
