Buick Reatta Rear Speaker Size
The Buick Reatta rear location accommodates a 6.5 inch speaker size. Compatible types for the rear include midbass and full-range speakers. These specifications cover the years 1990 to 1991.
| Year | Type | Size (inch) |
|---|---|---|
| 1991 | Midbass / Full-Range | 6.5 |
| 1990 | 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 rear speaker location in the Buick Reatta accommodates a 6.5 inch driver across the 1990 and 1991 model years.
- A 6.5 inch speaker occupies a mid-sized mounting footprint, requiring a rear cavity or panel opening with sufficient depth and diameter to seat the basket and magnet assembly without contact interference from surrounding structure.
- The 6.5 inch diameter places the cone surface area in a range suited to reproducing frequencies from the upper bass region through the lower midrange, roughly 60 Hz to 5 kHz depending on driver design.
- At the rear of the Buick Reatta's cabin, a 6.5 inch driver operates at a distance from the primary listening position, which affects the time-alignment relationship between front and rear sound sources.
- Midbass is a speaker type designed to handle the frequency band between bass and midrange, typically covering approximately 80 Hz to 500 Hz, reinforcing low-frequency body and punch without attempting to reproduce the full audio spectrum.
- A midbass driver installed in the rear location of the Reatta would concentrate energy in the lower portion of the 6.5 inch driver's capable range, supporting foundation frequencies rather than vocal or high-frequency content.
- Full-range is a speaker type engineered to reproduce a wide portion of the audible spectrum from a single driver, covering bass, midrange, and partial high-frequency content within one unit.
- A full-range driver in the rear position of the Reatta would distribute sound across a broader frequency span, allowing the rear location to contribute to midrange and upper-frequency reproduction in addition to bass.
- The 6.5 inch format is compatible with both midbass and full-range types in the Reatta's rear location, indicating the mounting dimensions support either a dedicated low-frequency driver or a wider-spectrum unit within the same physical opening.
