Memphis PRX27 2.75" 2-Way Coaxial Car Speakers

The Memphis PRX27 is a pair of compact 2.75-inch car speakers designed for replacing small factory speakers in compatible dash or other OEM locations. Their compact format addresses vehicles that use uncommon small speaker openings where larger aftermarket speakers will not fit. They are intended for car, truck, SUV, and van applications.

Each PRX27 speaker is rated for 15 watts RMS and 30 watts peak power at 4 ohms. With an 85 dB sensitivity rating and a 221-12,000 Hz frequency response, these speakers are suited to modest-power factory-radio or appropriately matched amplified systems. Their small drivers are focused on upper-bass, midrange, and high-frequency support rather than deep bass production.

The speakers use a paper cone and foam surround, combining low moving mass with a straightforward factory-replacement design. A PEI dome tweeter with a pivot mounting arrangement is listed for the Power Reference design. This 2-way configuration helps add detail and presence in small speaker locations.

The PRX27 belongs to Memphis Audio's Power Reference series and is sold as a pair. It can be used to replace worn or blown small OEM speakers when the vehicle's opening, mounting pattern, and available depth are compatible. Verify the factory wiring arrangement and impedance requirements before installation, especially in vehicles with factory amplification.

With a 2-5/8-inch cutout requirement and a listed top-mount depth of 1-3/8 inch, the PRX27 is designed for shallow small-speaker locations. Factory grilles may be reused where applicable because separate grilles are not included. Mounting hardware and wire caps are listed among the included accessories.

Key Features

• Compact 2.75-Inch Size: Fits compatible small factory speaker locations.
• 2-Way Coaxial Design: Combines a small driver and tweeter.

• Paper Cone: Provides a lightweight driver diaphragm.
• Foam Surround: Supports controlled cone movement.
• 4-Ohm Impedance: Works with compatible car audio outputs.

Design & Installation

The PRX27 uses a black finish with a paper cone and foam surround. Memphis documentation for the Power Reference design also identifies a polyurethane surround, PEI dome tweeter, and pivot tweeter mount; confirm the physical configuration of the supplied speakers before planning a custom installation. No illumination, damping kit, or separate speaker grilles are included.

Confirm that the vehicle accepts a 2.75-inch speaker, a 2-5/8-inch cutout, and the required mounting depth before ordering. The pair includes mounting screws, mounting clips, and wire caps, but no external crossovers are included. Use the existing factory grille only when clearance and fitment are appropriate, and avoid overpowering the 15-watt RMS rating per speaker.
