Acura TSX Front Door Panel Speaker Size
The Acura TSX front door panel accommodates 1 inch and 6.5 inch speaker size units. Compatible types across the audio system include tweeters and midbass or full-range replacement speakers. These specifications cover the 2004 to 2014 model chart range.
| Year | Type | Size (inch) |

| 2014 | Tweeter | 1 |
| 2014 | Midbass / Full-Range | 6.5 |
| 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 | Midbass / Full-Range | 6.5 |
| 2007 | Midbass / Full-Range | 6.5 |
| 2006 | Midbass / Full-Range | 6.5 |
| 2005 | Midbass / Full-Range | 6.5 |
| 2004 | 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 Acura TSX front door panel accommodates 2 distinct speaker sizes across the listed model years: a 6.5 inch position and a 1 inch position.
- The 6.5 inch mounting location in the front door panel is sized to accept either a midbass or full-range driver, with the door cavity providing the enclosure volume and low-frequency boundary reinforcement typical of door-mounted woofer positions.
- A 6.5 inch driver in a front door location handles the lower-midrange and upper bass frequencies, generally covering the range from approximately 60 Hz to 4 kHz depending on crossover configuration, which corresponds to the primary energy range of vocals, guitars, and bass instruments.
- The midbass type in a 6.5 inch front door position is designed to reproduce bass and lower-midrange frequencies with reduced excursion distortion at higher output levels, operating most effectively when crossed over to a dedicated high-frequency driver above a set frequency point.
- A full-range driver at the 6.5 inch front door position is designed to reproduce a wide frequency band without requiring a separate tweeter, though high-frequency dispersion from a larger cone is inherently narrower than from a dedicated 1 inch tweeter.
- The 1 inch tweeter position in the Acura TSX front door panel is listed as compatible across the 2009 through 2014 model years, indicating a dedicated high-frequency mounting location introduced with or before the 2009 model year in the door panel.
- A 1 inch tweeter driver reproduces high frequencies typically from around 2 kHz to 20 kHz, and the small diaphragm diameter allows for wide dispersion of high-frequency sound energy across the cabin interior from a front door mounting point.
- Placement of a 1 inch tweeter within the front door panel positions the high-frequency source at a lower height than an A-pillar or dash location, which affects the perceived soundstage height and the angle of high-frequency incidence relative to seated occupants.
- The front door panel location places the primary 6.5 inch driver close to the listener's lower body level, which means low-frequency output benefits from proximity to the floor and door boundary surfaces, reinforcing bass response through acoustic loading.
- Door panel installations expose drivers to environmental factors including moisture from window seals and mechanical vibration from the door structure, both of which are relevant to the durability ratings of replacement drivers chosen for the 6.5 inch position.
- The simultaneous presence of both a 1 inch and a 6.5 inch position in the same front door panel from 2009 onward indicates a 2-way speaker arrangement within a single door, where the frequency spectrum is divided between the 2 drivers.
