Peugeot 308 Rear Door Panel Speaker Size

Additional Notes

• The Peugeot 308 rear door panel is a flush-mounted location integrated into the interior trim of the rear passenger doors, positioning speakers within the lower-to-mid section of the door cavity.
• Door panel installations place speakers inside an enclosed cavity, where the door structure itself acts as an enclosure, influencing bass response and cone loading for any driver mounted there.
• A 6.5 inch driver occupies a mounting cutout of approximately 5.5 to 5.75 inches in baffle diameter, requiring sufficient door panel depth and structural clearance behind the cone to avoid physical contact with internal door components.
• The 6.5 inch size in a rear door panel location produces lower midrange and midbass frequencies effectively, typically covering a range from around 60 Hz up to 5 kHz, making the door cavity a functional enclosure for reinforcing body and warmth in the audio reproduction.
• Midbass drivers in the 6.5 inch format are optimized for handling the 80 Hz to 500 Hz range with greater cone excursion capability, which suits the acoustic demands of a rear door location where low-frequency reinforcement is a primary contribution to the overall sound stage.
• Full-range drivers of the same 6.5 inch format are designed to reproduce a wider frequency span from bass through upper midrange within a single driver, relying on cone geometry and surround compliance to extend response beyond the typical midbass ceiling.
• The Peugeot 308 rear door panel, in model years 2022 through 2025, accommodates a 1 inch tweeter position alongside the 6.5 inch driver, indicating the presence of a dedicated high-frequency mounting point within the same door panel assembly.
• A 1 inch tweeter handles high-frequency reproduction, typically from around 2 kHz to 20 kHz, and in a door panel context the placement height and angle of the tweeter mount significantly affect stereo imaging and high-frequency dispersion toward rear passengers.
• Tweeters of the 1 inch dome variety have a wide dispersion pattern at lower treble frequencies, narrowing at higher frequencies, which interacts with the reflective and absorptive surfaces within the rear door and cabin trim panels.
• The rear door panel location places speakers at a lower height relative to ear level for seated rear passengers, which can affect the perceived directionality of midrange frequencies produced by the 6.5 inch driver, as midrange becomes increasingly directional above approximately 1 kHz.
• The coexistence of a 6.5 inch and a 1 inch position within the rear door panel from 2022 onward indicates a two-way speaker arrangement is supported in that location, where crossover filtering would typically divide frequency duties between the midbass and tweeter drivers.
• From 2007 through 2021, the rear door panel specifications list only the 6.5 inch position, indicating a single driver mounting location per rear door during those model years.
