Honda CRX Rear Door Panel Speaker Size
The Honda CRX 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 1988 to 1989 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 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 rear door panel location in the Honda CRX accommodates speakers mounted within the door structure, where the panel surface and internal cavity depth determine the maximum basket diameter and magnet clearance available for installation.
- A 6.5 inch speaker in a door panel position is subject to the physical constraints of the door's inner skin, vapor barrier, and available mounting depth, all of which affect the cone's ability to move freely without obstruction.
- The 6.5 inch diameter is a mid-size driver format that reproduces frequencies roughly between 60 Hz and 5 kHz, a range suited to the door panel location where lower-midrange and upper-bass content benefits from the natural baffle effect of the door structure itself.
- In a door-mounted position, a 6.5 inch cone has sufficient surface area to move air at lower frequencies while remaining small enough to maintain controlled dispersion at mid frequencies, which is relevant given the lateral listening angle typical of door placements relative to seated occupants.
- Midbass drivers, as listed for the 1988 and 1989 Honda CRX rear door panel, are designed with stiffer suspensions and motor systems optimized for the 80 Hz to 500 Hz range, prioritizing cone control over extended high-frequency response.
- Full-range drivers listed for the same location are built to reproduce a wider frequency band within a single driver, typically handling bass, midrange, and limited treble without requiring additional components in the same mounting position.
- The rear door panel placement positions the speaker low in the vehicle interior, which affects the directional projection of mid and upper frequencies toward the listening area and influences how much of the high-frequency output reaches occupants at ear level.
- Door panel cavities often introduce acoustic resonances due to the metal enclosure formed by the door shell, which can interact with the low-frequency output of a 6.5 inch driver operating in midbass or full-range capacity.
- The compatibility of both midbass and full-range types with the same 6.5 inch mounting cutout in the Honda CRX rear door panel indicates the location shares a common physical opening size across both driver categories listed in the specifications.
