Honda CR-Z Rear Side Panel Speaker Size
The Honda CR-Z rear side panel accommodates a 6.5 inch speaker size across all listed model years. Compatible speaker types for the location include midbass and full-range units. The specifications cover a range of years from 2011 to 2016.
| Year | Type | Size (inch) |
|---|---|---|
| 2016 | Midbass / Full-Range | 6.5 |
| 2015 | Midbass / Full-Range | 6.5 |
| 2014 | Midbass / Full-Range | 6.5 |
| 2013 | Midbass / Full-Range | 6.5 |
| 2012 | Midbass / Full-Range | 6.5 |
| 2011 | 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 side panel location in the Honda CR-Z positions speakers within the lateral interior walls toward the rear of the cabin, a placement that affects soundstage width and the distribution of audio energy across the passenger compartment.
- A 6.5 inch driver occupies a mid-sized cone area, producing sufficient diaphragm surface to move air effectively in the lower and middle portions of the audible frequency spectrum, roughly from around 60 Hz up through several kilohertz depending on crossover configuration.
- The rear side panel mounting orientation typically places the driver firing inward toward the cabin rather than upward or rearward, which influences how direct and reflected sound reach the listening position.
- A 6.5 inch speaker in a side panel enclosure interacts with the panel cavity behind it, meaning the volume of air behind the cone affects bass extension and cone control at lower frequencies.
- The midbass type is designed to handle the lower-midrange and upper-bass frequency bands, generally covering roughly 80 Hz to 500 Hz, where kick drum, bass guitar fundamentals, and lower vocal harmonics reside.
- A midbass driver at the rear side panel location contributes low-frequency body and warmth to the overall system, reinforcing the bass content produced by dedicated subwoofers or the lower roll-off of front speakers.
- The full-range type is engineered to reproduce a broad portion of the audible spectrum from bass through treble using a single cone, making Honda CR-Z rear side panel full-range drivers capable of operating without a dedicated crossover network.
- Full-range speakers in the rear side panel position reproduce mid and high frequencies from a lateral rear source, which places treble content at an angle and distance from front-seat listeners that differs from a dash or door-mounted tweeter.
- The 6.5 inch diameter is a standard automotive speaker size, and the circular cutout dimension and mounting depth requirements associated with 6.5 inch drivers must align with the rear side panel cavity depth available in the CR-Z's body structure.
- The rear side panel location is structurally distinct from door locations in that the mounting surface is fixed rather than moveable, which eliminates variables caused by door sealing but also means the acoustic chamber behind the driver is determined entirely by the panel void.
