Compatible speaker types across these locations include tweeters, midrange, midbass, full-range, and woofer. The specifications cover a range of years from 2000 to 2009.

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. |
| 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. |
| 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. |
| Woofer | A larger driver for low frequencies, typically from about 40 Hz up to 1,000 Hz. It delivers most of the bass and lower midrange in a door or panel speaker system. |
| 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 front door panel location in the Audi TT positions speakers within the interior door cavity, where the mounting surface faces the cabin laterally, directing sound toward the occupants from the lower side of the listening plane.
- Door panel installations are subject to dimensional constraints from the door's inner structure, including the window mechanism, door card thickness, and available cutout diameter, all of which determine which speaker sizes can be accommodated at each position.
- The 6.5 inch size appears across all model years in the specifications and is suited to the front door panel location because door cavities generally support the cone excursion and basket depth required for mid-to-low frequency reproduction in that diameter range, typically covering approximately 80 Hz to 5 kHz.
- As a midbass driver in the front door panel, a 6.5 inch speaker handles the lower midrange and upper bass frequencies that benefit from the door's proximity to the floor and its coupling with the door cavity as a partial acoustic enclosure.
- When a 6.5 inch speaker is used as a full-range driver in the front door panel, a single cone is responsible for the entire audible spectrum at that location, relying on the door mounting surface for structural support across the full excursion range.
- The 3.5 inch size listed for 2008 and 2009 operates as a midrange driver, covering the vocal and presence frequencies - roughly 300 Hz to 5 kHz - where the smaller cone mass allows faster transient response than a larger woofer cone at the same location.
- The 8 inch woofer listed for 2008 and 2009 in the Audi TT front door panel requires a larger cutout and greater mounting depth than the other sizes at that location, and at that diameter a woofer reproduces low-frequency content typically below 200 Hz, using the door cavity as a partial baffle to support bass output.
- The 2 inch tweeter listed for model years 2000 through 2006 occupies a secondary mounting point within the front door panel, separate from the larger 6.5 inch cutout, as tweeters require only minimal enclosure depth due to their small, rigid dome or cone diaphragm.
- A 2 inch tweeter in the front door panel reproduces high frequencies generally above 3 kHz to 5 kHz, where the directional nature of high-frequency sound makes the lateral, ear-level positioning of the door panel relevant to imaging and dispersion in the cabin.
- The front door panel placement of a tweeter at the 2 inch size means high-frequency sound originates from a position closer to seat height than a dash-mounted tweeter, which affects the vertical angle of incidence relative to the listening position.
- The coexistence of a 2 inch tweeter and a 6.5 inch midbass or full-range driver within the same front door panel indicates 2 distinct mounting locations on the door card, each sized to their respective diameter cutouts.
- For the 2008 and 2009 model years, the front door panel accommodates 3 distinct speaker sizes - 3.5 inch, 6.5 inch, and 8 inch - indicating 3 separate mounting positions within the door structure at those model years.
