Mazda Protege5 Rear Door Panel Speaker Size
The Mazda Protege5 rear door panel accommodates a 6.5 inch speaker size. Compatible types for the location include midbass and full-range units. These specifications cover the 2002 to 2003 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2003 | Midbass / Full-Range | 6.5 |
| 2002 | 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 door panel location on the Mazda Protege5 accommodates a 6.5 inch speaker opening across the 2002 and 2003 model years.
- A 6.5 inch driver mounted in a door panel sits at roughly seat-level height, which positions the sound source low relative to the listener's ears and influences the perceived stereo imaging from the rear of the cabin.
- Door panel cavities introduce reflective and resonant surfaces behind the cone, meaning the acoustic environment around a 6.5 inch driver in the Mazda Protege5 rear door is influenced by the door's internal volume and any factory damping material present.
- The 6.5 inch diameter is a mid-size format that supports a cone area large enough to move sufficient air for lower midrange and upper bass reproduction while remaining physically compact enough for typical door panel recesses.
- A midbass driver in the rear door panel role handles the lower midrange and upper bass frequency band, generally covering roughly 80 Hz to 500 Hz, reinforcing body and warmth in the overall cabin sound.
- A full-range driver in the rear door panel position handles a wider frequency span than a midbass unit, extending into the upper midrange and lower treble, which reduces the dependency on additional tweeters at the rear of the cabin.
- The rear door panel location on the Protege5 places the speaker firing inward toward the cabin occupants, with the door's sheet metal and trim acting as the baffle structure that supports the driver's surround and basket.
- Midbass drivers are typically designed with stiffer suspensions and lower resonant frequencies compared to full-range drivers of the same diameter, making the cone excursion characteristics and mounting depth relevant considerations for the rear door cavity.
- Full-range drivers of the 6.5 inch format used in a rear door position are often designed with a whizzer cone or extended dust cap to maintain treble dispersion across the cabin without a dedicated tweeter.
- The rear door panel mounting depth available in the Mazda Protege5 for a 6.5 inch driver determines whether shallow-mount or standard-mount versions of either compatible type can be installed without obstruction from window regulator hardware inside the door.
