Suzuki SX4 Rear Door Panel Speaker Size
The Suzuki SX4 rear door panel accommodates 1 inch speakers and a 6.5 inch speaker size. Compatible types include tweeters and midbass or full-range audio units. These specifications cover the 2007 to 2013 model range.
| Year | Type | Size (inch) |
|---|---|---|
| 2013 | Tweeter | 1 |
| 2013 | Midbass / Full-Range | 6.5 |
| 2012 | Tweeter | 1 |
| 2012 | Midbass / Full-Range | 6.5 |
| 2011 | Tweeter | 1 |
| 2011 | Midbass / Full-Range | 6.5 |
| 2010 | Tweeter | 1 |
| 2010 | Midbass / Full-Range | 6.5 |
| 2009 | Tweeter | 1 |
| 2009 | Midbass / Full-Range | 6.5 |
| 2008 | Tweeter | 1 |
| 2008 | Midbass / Full-Range | 6.5 |
| 2007 | Tweeter | 1 |
| 2007 | Midbass / Full-Range | 6.5 |
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. |
| Midbass | A driver tuned for upper bass and lower midrange, roughly from 80 Hz to 500 Hz. It has longer cone travel than a full-range unit, which supports stronger bass in doors and panels. |
| Full-Range | A single driver that reproduces bass through treble without a separate crossover network. It is the simplest replacement option and is common in factory audio systems. |
Additional Notes
- The Suzuki SX4 rear door panel is a mounted location within the vehicle's rear passenger doors, positioning speakers within the lower lateral sections of the cabin.
- Door panel installations place speakers closer to floor level than dash or pillar locations, which affects the upward projection angle of sound toward rear seat occupants.
- The 6.5 inch diameter specification accommodates a woofer cone surface area sufficient to move enough air for reproducing midbass and lower midrange frequencies, which require larger diaphragm excursion than high-frequency reproduction.
- In a rear door panel location, a 6.5 inch driver operating in midbass or full-range capacity handles the lower and mid frequencies that contribute to the body and warmth perceived by rear seat passengers.
- A full-range 6.5 inch driver is designed to reproduce a broad frequency spectrum from low bass through upper midrange, making the single driver responsible for the majority of audible sound output at the rear door position.
- A midbass 6.5 inch driver is optimized for the lower midrange and upper bass bands, typically operating most effectively between approximately 80 Hz and 500 Hz, and is intended to work alongside a separate high-frequency driver at the same location.
- The 1 inch tweeter specification is consistent with a dome or similar compact high-frequency driver, which reproduces treble frequencies generally above 2,000 Hz where the 6.5 inch driver's high-frequency output diminishes.
- Tweeters at 1 inch in diameter have a small diaphragm mass, which allows rapid pistonic movement necessary for accurate reproduction of upper harmonics and high-frequency transients in rear cabin audio.
- The presence of both a 1 inch tweeter and a 6.5 inch midbass or full-range driver within the same rear door panel location indicates the mounting space accommodates 2 discrete driver cutouts or a coaxial arrangement within the door panel structure.
- Rear door panel speaker positions in vehicles like the Suzuki SX4 are subject to acoustic boundary effects from the door's internal cavity, which can influence bass response and standing wave behavior of the 6.5 inch driver.
- The Suzuki SX4 rear door panel accepts a 1 inch tweeter across all listed model years, meaning any compatible tweeter replacement must conform to the physical mounting constraints of the factory 1 inch opening in that panel.
- High-frequency dispersion from a 1 inch tweeter mounted at door panel height projects sound at a relatively low angle relative to seated rear passengers, which influences the perceived stereo imaging in the rear cabin zone.
