Toyota Cressida Rear Deck Lid Speaker Size
The Toyota Cressida rear deck lid accommodates a 6.5 inch speaker size and 5x7 inch speakers, with each location supporting the unique speaker requirements across the model's production span. Compatible types for the 6.5 inch units include midbass and full-range, while the 5x7 inch units support full-range audio system configurations. These specifications cover the years 1979 through 1992.
| Year | Type | Size (inch) |
|---|---|---|
| 1992 | Midbass / Full-Range | 6.5 |
| 1991 | Midbass / Full-Range | 6.5 |
| 1990 | Midbass / Full-Range | 6.5 |
| 1981 | Full-Range | 5x7 |
| 1980 | Full-Range | 5x7 |
| 1979 | Full-Range | 5x7 |
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 Toyota Cressida rear deck lid is a flat, horizontal surface positioned at the rear of the cabin, behind the rear seats and above the trunk cavity, a location commonly associated with wide stereo imaging and rear-fill audio coverage.
- Mounting on a rear deck lid typically involves flush or surface-mounted installation within a flat baffle, where the speaker fires upward toward the rear windshield, which acts as a reflective surface that disperses sound forward into the cabin.
- The 6.5 inch round drivers listed for the 1990, 1991, and 1992 Cressida occupy a standardized circular cutout, and the round format concentrates cone excursion symmetrically, which supports controlled low-midrange reproduction in a rear deck environment.
- The 5x7 inch oval format listed for the 1979, 1980, and 1981 Cressida fits an elongated cutout, and the increased surface area of the oval cone relative to a standard round driver allows for greater low-frequency displacement within the same mounting depth constraint.
- A 6.5 inch driver is commonly associated with a frequency range spanning roughly 60 Hz to 5 kHz, making the rear deck position in the 1990-1992 Cressida capable of handling a substantial portion of the audible spectrum from a single mounting location.
- The 5x7 inch oval format, used in the 1979-1981 Cressida rear deck lid, produces directional characteristics that differ from round drivers due to the asymmetric cone shape, which can cause off-axis frequency response variations at higher frequencies.
- Midbass drivers, listed as compatible for the 1990-1992 Toyota Cressida rear deck lid, are designed to reproduce the lower midrange and upper bass frequencies, typically between approximately 80 Hz and 500 Hz, and are generally used as part of a multi-component speaker system rather than as standalone units.
- Full-range drivers, compatible with all model years listed in the specifications, are designed to reproduce the majority of the audible spectrum from a single driver, making the rear deck lid a self-contained source of broad frequency coverage across both the round and oval mounting formats.
- The rear deck lid location places speakers at ear level or above for rear-seat passengers, and the upward-firing orientation combined with the angle of the rear windshield affects how sound is reflected and perceived from front-seat listening positions.
- The 6.5 inch round format accommodates a larger magnet assembly than the 5x7 inch oval in many applications, which influences the driver's sensitivity and transient response characteristics at the rear deck mounting position.
