Additional Notes
- The D-pillar is the rearmost structural pillar in a multi-row SUV, positioned at the far back of the passenger cabin behind the third-row seating area.
- Speaker enclosures mounted in the D-pillar are typically shallow and space-constrained, as the pillar must also serve structural and trim functions within the vehicle body.
- The Dodge Durango D-pillar accepts a 2.5 inch driver across all listed model years, a diameter consistent with the limited mounting depth and surface area available in a rear pillar cavity.
- A 2.5 inch cone diameter limits low-frequency excursion, making a full-range or bass-reproducing role physically impractical at the D-pillar location.
- The compact diameter of a 2.5 inch driver produces a relatively narrow sound dispersion pattern at higher midrange frequencies, which affects how evenly audio reaches passengers in the third row.
- Midrange drivers are designed to reproduce the frequency band roughly between 300 Hz and 5,000 Hz, covering the core of vocal intelligibility and many instrument fundamentals.
- In a rear-pillar location, a midrange driver reinforces audio presence for rear-cabin occupants who are positioned at greater distance from front-mounted speakers.
- Because the D-pillar sits at ear level or slightly above for third-row passengers, a midrange driver at the Dodge Durango D-pillar location operates within a relatively direct acoustic path to those seated nearby.
- Midrange drivers are not designed to handle the low-frequency demands that woofers or subwoofers address, nor the high-frequency extension of tweeters, so the D-pillar in the Durango functions as a mid-band fill position rather than a full-range source.
- The consistent 2.5 inch midrange specification across all listed model years indicates a uniform mounting cutout and depth at the D-pillar position throughout the covered production range.
