Mercedes-Benz CLK320 Rear Deck Lid Speaker Size
The Mercedes-Benz CLK320 rear deck lid accommodates a 6.5 inch speaker size and 3.5 inch speakers within the same location. Compatible audio types for the system include midbass and full-range replacement units. These specifications cover the 1998 to 2002 model range.
| Year | Type | Size (inch) |
|---|---|---|
| 2002 | Midbass / Full-Range | 6.5 |
| 2001 | Midbass / Full-Range | 6.5 |
| 2000 | Midbass / Full-Range | 6.5 |
| 2000 | Full-Range | 3.5 |
| 1999 | Midbass / Full-Range | 6.5 |
| 1998 | 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 deck lid of the Mercedes-Benz CLK320 is a horizontal surface positioned at the base of the rear windshield, above the trunk cavity, a placement that radiates sound upward and forward into the cabin.
- A 6.5 inch driver in the rear deck lid position spans a cone area sufficient to move enough air for meaningful low-midrange and midbass reproduction, which reinforces the lower frequencies that travel well across the cabin length.
- The 3.5 inch size listed for the 2000 model year at the rear deck lid location represents a significantly smaller cone area, which limits low-frequency extension and air displacement relative to the 6.5 inch position on the same vehicle.
- A 3.5 inch driver at the rear deck lid is acoustically suited to upper-midrange and high-midrange reproduction, as smaller cone diameters maintain better pistonic motion at elevated frequencies than larger drivers.
- The midbass type is defined by a driver optimized for the frequency range roughly between 80 Hz and 500 Hz, where fundamental tones of bass instruments and lower vocal harmonics reside, making the 6.5 inch midbass placement at the rear deck effective for foundational tonal support.
- A full-range type driver is designed to reproduce a wide frequency band from bass through treble within a single unit, without relying on a crossover network to divide the signal before the driver.
- The 3.5 inch full-range driver in the 2000 Mercedes-Benz CLK320 rear deck lid shares a location with a separate 6.5 inch position, indicating the deck lid accommodates 2 distinct mounting cutouts of different diameters in that model year.
- The rear deck lid position, being a rigid panel over an enclosed trunk space, can exhibit resonance behavior where the trunk cavity acts as a back-loaded enclosure, influencing the low-frequency response of any driver mounted there.
- The 6.5 inch midbass type at the rear deck lid is oriented to handle frequencies that benefit from the acoustic loading of the enclosed trunk volume behind the mounting surface, as sealed enclosures support cone control at lower frequencies.
- Mounting depth clearance at the rear deck lid is constrained by the panel thickness and the space between the deck surface and the trunk interior structures, which affects the acceptable basket depth of any 6.5 inch or 3.5 inch driver installed there.
