The Mazda RX-8 rear location accommodates a 6x8 inch speaker size and 6x9 inch speakers, covering the unique size variations across the model's production range. Full-range units represent the compatible audio system types for the rear installation. These specifications cover the 2009 to 2011 model years.
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 speaker location in the Mazda RX-8 accommodates oval speaker formats, with specifications showing either 6x8 inch or 6x9 inch mounting dimensions depending on the model year.
Oval speaker cutouts in rear deck or rear panel positions are typically governed by the structural geometry of the vehicle's body, which explains why two distinct oval sizes appear across the RX-8's production run.
The 6x8 inch format listed for the 2010 Mazda RX-8 rear position has a slightly smaller cone area than the 6x9 inch format, which affects the volume of air the driver can displace and consequently the lower frequency extension the speaker can produce in that location.
The 6x9 inch format, present across the 2009, 2010, and 2011 model years, offers a larger radiating surface than the 6x8 inch format, allowing for greater low-frequency output from the rear of the cabin.
Rear deck or rear panel placements, such as those found in the RX-8, typically allow oval speakers to take advantage of trunk or cargo cavity coupling, which can reinforce bass reproduction from full-range drivers.
Full-range speakers, the only compatible type listed across all rows, are single drivers designed to reproduce a wide portion of the audible frequency spectrum, from low-frequency bass through midrange and into the upper treble frequencies.
A full-range driver in a rear location handles low, mid, and high frequencies without requiring a dedicated crossover network or supplementary tweeter, making the single-driver configuration self-contained at the mounting point.
The rear position in the RX-8 is spatially separated from the front listening area, and full-range drivers placed there contribute to ambient and diffuse soundfield qualities by reproducing the full spectrum from behind the occupants.
The 2010 model year is the only year in the specifications with 2 distinct rear speaker size entries, indicating that 6x8 inch and 6x9 inch mounting configurations both appear as valid rear fitments for that year.
