Mercedes-Benz E350 Floor Below Center of Dash Speaker Size
The Mercedes-Benz E350 floor below center of dash location accommodates an 8 inch speaker size. Subwoofer units are the compatible replacement types suited for that audio system position. These specifications cover the 2017 to 2025 model years.
| Year | Type | Size (inch) |
|---|---|---|
| 2025 | Subwoofer | 8 |
| 2024 | Subwoofer | 8 |
| 2023 | Subwoofer | 8 |
| 2022 | Subwoofer | 8 |
| 2021 | Subwoofer | 8 |
| 2020 | Subwoofer | 8 |
| 2019 | Subwoofer | 8 |
| 2018 | Subwoofer | 8 |
| 2017 | Subwoofer | 8 |
Speaker Types
| Type | Description |
|---|---|
| Subwoofer | A large driver for the lowest bass notes, typically from about 20 Hz to 120 Hz. It is usually installed in a separate enclosure and works alongside the other speakers. |
Additional Notes
- The floor below center of dash location in the Mercedes-Benz E350 places a speaker at the lowest point of the cabin interior, positioned centrally between the driver and front passenger footwells.
- A floor-mounted position situates the speaker enclosure near a structural surface shared by the firewall and transmission tunnel, which can influence low-frequency boundary reinforcement through proximity to rigid panels.
- The 8 inch diameter across all listed model years indicates a cone surface area suited to reproducing low-frequency content, as larger cone diameters move greater air volume, which is a mechanical requirement for generating bass frequencies.
- An 8 inch driver occupies a moderate footprint within the subwoofer category, falling between compact 6.5 inch units and larger 10 inch or 12 inch alternatives, allowing a balance between physical enclosure depth and low-frequency output in a space-constrained floor location.
- The subwoofer type is defined by its operating range, which typically spans approximately 20 Hz to 200 Hz, handling the lowest frequencies in a multi-speaker system while higher-frequency reproduction is delegated to other drivers in the vehicle.
- Subwoofers are generally non-directional at low frequencies due to the long wavelengths involved, which makes the floor below center of dash a viable placement since human hearing cannot easily localize the source of bass below roughly 80 Hz.
- The Mercedes-Benz E350 floor below center of dash location accepts only subwoofer-type drivers, meaning the opening is not listed as compatible with full-range speakers, coaxial units, or tweeters across any of the covered model years.
- An 8 inch subwoofer in a floor-mounted position benefits from the cabin floor acting as a baffle, with floor and seat surfaces reflecting low-frequency energy back into the listening area rather than allowing rearward radiation to dissipate.
- The depth clearance required by an 8 inch subwoofer is a relevant spatial factor in a floor installation, as the mounting cavity must accommodate both the basket depth of the driver and any required enclosure volume without interference from underfloor components.
- The consistent 8 inch subwoofer specification across the 2017 through 2025 model years indicates dimensional uniformity in the floor below center of dash cavity across all listed generations of the E350.
