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 Audi S6 rear door panel accommodates a 2-speaker configuration across most model years, pairing a small tweeter with a mid-sized woofer within the same door panel cavity.
- Rear door panel locations impose physical depth and baffle width constraints, and the 6.5 inch midbass/full-range driver fits within a mounting cutout typical of mid-sized door cavities found in full-size sedans and wagons.
- The 5.25 inch midbass/full-range driver, specified for 2002 and 2003 model years, occupies a smaller mounting diameter than the 6.5 inch counterpart, indicating a reduced rear door baffle opening in those earlier production variants.
- A 6.5 inch driver in a rear door panel position radiates low-to-mid frequencies into the cabin from a laterally angled surface, reinforcing bass and lower midrange energy toward the rear seating area.
- The 5.25 inch midbass/full-range driver reproduces a frequency range similar to the 6.5 inch but with reduced low-frequency extension and lower maximum output due to the smaller cone surface area, which is consistent with the tighter door panel space in the 2002 and 2003 S6.
- The 0.75 inch tweeter, listed for 2013 through 2018 and also for 2002 and 2003 model years, handles high-frequency reproduction typically above 3,500 Hz to 5,000 Hz, where short wavelengths demand a small, light diaphragm for accurate transient response.
- The 1 inch tweeter, specified for 2007 through 2011 model years, has a marginally larger diaphragm than the 0.75 inch unit, which can affect the crossover point and the upper frequency limit before beaming occurs at high frequencies.
- Tweeters mounted within rear door panels project high-frequency content toward the interior at a low height relative to ear level, which influences the perceived stereo imaging and soundstage width for rear-seat passengers.
- The Audi S6 rear door panel tweeter opening distinguishes between 0.75 inch and 1 inch mounting formats across different generation ranges, meaning a tweeter specified for 2007-2011 models is not dimensionally interchangeable with the 2013-2018 S6 rear door panel without a mounting adapter.
- The 1995 S6 rear door panel specification lists only the 6.5 inch midbass/full-range driver, with no tweeter position included in the rear door panel data.
- Door panel speaker locations are subject to acoustic loading from the internal door cavity volume, and the 6.5 inch driver benefits from that enclosed rear volume, which can extend perceived bass response compared to an open-back mounting configuration.
- Full-range drivers in the rear door panel position cover a wide frequency span from low bass through upper midrange, while the co-located tweeter extends reproduction above the point where cone break-up or roll-off limits the larger driver's high-frequency accuracy.
