Audi 80 Rear Deck Lid Speaker Size
The Audi 80 rear deck lid accommodates a 6.5 inch speaker size across all listed model years. Compatible speaker types for the location include midbass and full-range units. These specifications cover a range of years from 1988 to 1992.
| Year | Type | Size (inch) |
|---|---|---|
| 1992 | Midbass / Full-Range | 6.5 |
| 1991 | Midbass / Full-Range | 6.5 |
| 1990 | Midbass / Full-Range | 6.5 |
| 1989 | Midbass / Full-Range | 6.5 |
| 1988 | Midbass / Full-Range | 6.5 |
Speaker Types
| Type | Description |
|---|---|
| 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 80 rear deck lid is a horizontal surface positioned at the base of the rear window, spanning the width of the cabin above the trunk compartment.
- Speakers mounted in a rear deck lid position fire upward toward the headliner and rear glass, which influences sound reflection and cabin dispersion characteristics.
- The 6.5 inch driver diameter specified for the Audi 80 rear deck lid represents a mid-sized woofer format capable of producing bass and lower midrange frequencies with a reasonably wide cone area for low-frequency displacement.
- A 6.5 inch driver in a rear deck location benefits from the enclosed or semi-enclosed trunk cavity behind the mounting surface, which can act as an acoustic chamber contributing to low-frequency reproduction.
- The midbass type compatible with the Audi 80 rear deck lid (Audi 80 + 6.5 inch + rear deck) is a driver optimized for the frequency range roughly between 80 Hz and 500 Hz, reinforcing bass punch and lower vocal body without extending into high-frequency territory.
- Midbass drivers are typically designed with stiffer cone materials and stronger motor assemblies to handle the mechanical demands of low-frequency excursion in a baffle-mounted rear deck configuration.
- The full-range type compatible with the rear deck lid spans a broader frequency band, generally from around 60 Hz up to 20 kHz, covering bass, midrange, and treble reproduction from a single driver.
- Full-range drivers in a rear deck position distribute sound across the entire audible spectrum from behind and below the rear passengers, which affects the perceived front-to-rear soundstage balance within the cabin.
- The rear deck lid mounting plane in the Audi 80 is largely flat and horizontal, requiring a driver depth shallow enough to avoid contact with the trunk space or structural bracing beneath the panel.
- A 6.5 inch cutout in a rear deck lid typically requires a mounting depth consideration, as the cone assembly and magnet structure of the driver must clear any internal obstructions below the deck surface.
