Acura Integra Rear Door Panel Speaker Size
The Acura Integra rear door panel accommodates a 6.5 inch speaker size across all listed model years. Compatible types for the location include midbass and full-range audio system units. These specifications cover the 2023 to 2025 range of model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2025 | Midbass / Full-Range | 6.5 |
| 2024 | Midbass / Full-Range | 6.5 |
| 2023 | 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 Acura Integra accepts a 6.5-inch speaker across the 2023, 2024, and 2025 model years.
- A 6.5-inch speaker occupies a mid-sized mounting footprint, typically requiring a cutout diameter in the range of approximately 5.5 to 6 inches with a standard basket depth that must clear the inner door cavity and any window regulator hardware behind the panel.
- Door panel locations are generally surface-mounted against the interior trim, meaning the speaker frame seats flush against the mounting surface with the cone projecting inward toward the cabin rather than into open air.
- The rear door position places the speaker low and to the side of seated occupants, an orientation that influences how low-frequency energy propagates into the cabin compared to dash or rear deck placements.
- A 6.5-inch cone area is large enough to move sufficient air for meaningful low-midrange and upper-bass reproduction, with the driver's excursion capability being a primary factor in how deep the bass extension reaches at that diameter.
- Midbass is one of the 2 compatible types listed for the Acura Integra rear door panel location; in acoustic terms, a midbass driver is optimized to handle frequencies roughly from the upper bass range through the lower midrange, typically around 80 Hz to 500 Hz, without attempting to reproduce high-frequency content.
- Because a midbass driver at the rear door panel concentrates energy in the lower portion of the frequency spectrum, crossover filtering is a standard requirement when pairing a midbass unit with separate tweeters or midrange drivers elsewhere in the vehicle.
- Full-range is the other compatible type listed for the rear door panel; a full-range driver is designed to reproduce a wider span of frequencies from bass through treble within a single cone, often incorporating a small whizzer cone or other mechanism to extend high-frequency dispersion.
- At the rear door panel position, a full-range driver's high-frequency output is subject to directional limitations since the driver faces laterally rather than toward the listening position at ear level, which affects treble perceived by front-seated occupants.
- The 6.5-inch format is a broadly standardized size in automotive audio, and the Acura Integra rear door panel's use of 6.5-inch compatibility indicates the mounting ring diameter and depth clearance in the door conform to the dimensional envelope associated with that speaker class.
