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 is a structural column running along the front windshield edge, positioning speakers at ear level near the front occupants.
- A-pillar speaker enclosures are typically shallow and narrow, requiring drivers with compact basket dimensions and minimal mounting depth.
- The 2016 Cadillac ATS A-pillar position accepts a 1-inch driver, a diameter associated with tweeters designed to operate in high-frequency ranges, generally from around 2 kHz up to 20 kHz or beyond.
- A 1-inch tweeter dome radiates high-frequency sound with relatively wide dispersion at upper frequencies, making the A-pillar placement effective for directing treble content toward the listening position.
- Tweeters are transducers engineered to reproduce only high-frequency audio content, relying on crossover networks to block low and midrange frequencies that would otherwise distort or damage the driver.
- The A-pillar location places the tweeter close to the listener's ear height and at a forward angle, which reduces time-alignment discrepancies between the tweeter and other speakers in a front-stage configuration.
- The small physical mass of a 1-inch tweeter diaphragm allows rapid acceleration and deceleration, which is mechanically necessary for accurate reproduction of high-frequency transients.
- Installation in an A-pillar pod typically involves a pre-molded housing integrated into the interior trim, meaning aftermarket replacement drivers must conform to the 1-inch mounting cutout to fit without modification.
