Acura ZDX A-Pillar Speaker Size
The Acura ZDX A-Pillar accommodates a 1.5 inch speaker size across all applicable model years. Tweeter units are the compatible speaker type for the location. These specifications cover the 2010 to 2013 model year range.
| Year | Type | Size (inch) |
|---|---|---|
| 2013 | Tweeter | 1.5 |
| 2012 | Tweeter | 1.5 |
| 2011 | Tweeter | 1.5 |
| 2010 | Tweeter | 1.5 |
Speaker Types
| Type | Description |
|---|---|
| Tweeter | A small driver built for high frequencies, typically from about 2,000 Hz to 20,000 Hz. It adds treble detail and clarity and is usually mounted near ear level or aimed at the listener. |
Additional Notes
- The A-pillar location sits at the front corners of the cabin, where the windshield meets the front doors, positioning speakers at ear level and toward the forward soundstage.
- A-pillar mounting places drivers close to the listening position, which reduces the distance sound must travel before reaching occupants seated in the front row.
- The 1.5-inch diameter of the Acura ZDX A-pillar speaker opening reflects a cavity sized specifically for compact high-frequency drivers, as the narrow structural channel of an A-pillar physically limits the diameter of any installed speaker.
- A 1.5-inch driver has a small cone surface area, which limits low-frequency displacement but allows rapid, accurate movement suited to reproducing high-frequency content above approximately 2,000 Hz.
- The tweeter type is a high-frequency transducer designed to handle the upper portion of the audible spectrum, generally covering frequencies from around 2,000 Hz to 20,000 Hz.
- Tweeters reproduce the frequencies associated with upper harmonics, transients, and detail such as consonants in vocals and the attack of stringed instruments.
- The A-pillar position directs tweeter output toward the listening area from a forward angle, which contributes to imaging and the perception of sound source placement across the front of the cabin.
- Because tweeters are highly directional at upper frequencies, placement in the A-pillar allows the driver to aim high-frequency output toward the occupants rather than across or away from them.
- The 1.5-inch tweeter size in the Acura ZDX A-pillar is consistent across all 4 model years covered in the specifications, from 2010 through 2013.
- A 1.5-inch tweeter requires a relatively shallow mounting depth compared to larger driver types, which aligns with the limited depth available within an A-pillar trim panel.
