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 vertical structural column in an SUV body, positioning speakers at the furthest point from the front seats and closest to third-row or cargo-area occupants.
- Mounting at the D-pillar places drivers within a narrow, enclosed panel section, which constrains the available speaker diameter and depth relative to locations like door panels or rear decks.
- A 3.5-inch driver operates across a frequency range generally spanning from approximately 150 Hz to 5,000 Hz, covering upper bass through lower treble detail, though its primary acoustic contribution falls in the midrange band.
- The compact diameter of a 3.5-inch cone limits low-frequency displacement, meaning the driver cannot move sufficient air volume to reproduce deep bass effectively at the D-pillar position.
- The Honda Pilot D-pillar mounting location, combined with a 3.5-inch midrange driver, is acoustically suited to delivering vocal and instrumental clarity to rear cabin zones rather than full-range reproduction.
- Midrange speakers are designed to reproduce the frequency band where human speech and the fundamental tones of most acoustic instruments are concentrated, generally between 300 Hz and 5,000 Hz.
- At a rearward pillar location, a midrange driver contributes to fill and ambient soundstage for rear passengers, supplementing lower frequencies typically handled by dedicated woofers positioned elsewhere in the vehicle.
- The 3.5-inch form factor in a pillar mount typically requires a shallow mounting depth to clear internal pillar bracing and trim panels, making cone excursion and power handling more limited than equivalent drivers in door or deck locations.
- Midrange drivers at a D-pillar position radiate sound into the rear cabin at angles influenced by the pillar's geometry, which in an SUV typically aims dispersion inward toward seating rows rather than directly rearward.
