Memphis PRXP3 3.5" 2-Way Coaxial Speakers

The Memphis PRXP3 is a compact 3.5-inch 2-way coaxial speaker designed as a direct sound-quality upgrade for many factory speaker locations. Its shallow profile helps address installations where space behind the factory grille is limited. This model is intended for listeners replacing small OEM speakers in dash, door, or other factory positions.

With 15 watts RMS and 30 watts peak power handling per speaker, the PRXP3 is suited to lower-power factory radios and modest aftermarket amplification. Its 87 dB sensitivity supports practical output from systems that do not use a high-power external amplifier. Match the speaker to a compatible 4-ohm audio channel and stay within its continuous power rating.

The speaker uses a low-profile point source tweeter to keep the coaxial assembly compact under factory grilles. A silk dome tweeter handles upper-frequency detail, while the integrated 6 dB tweeter crossover directs appropriate frequencies to the tweeter. This arrangement avoids the need for a separate external crossover for the tweeter section.

A graphite-reinforced polypropylene woofer cone and rubber surround form the foundation of the PRXP3 design. These materials are selected for everyday automotive use and controlled cone movement. The result is a straightforward full-range replacement speaker with a smooth, balanced presentation for small factory locations.

The PRXP3 can be used as part of a factory-radio refresh or alongside larger replacement speakers elsewhere in the vehicle. Its 1.5-inch mounting depth and low-profile tweeter are useful where grille clearance is a concern. Confirm the available mounting depth, cutout size, wiring connection, and vehicle-specific fitment before installation.

Key Features

• 3.5-Inch 2-Way Design: Combines woofer and tweeter performance in one compact coaxial speaker.
• Point Source Tweeter: Low-profile tweeter design helps preserve clearance beneath factory grilles.
• Silk Dome Tweeter: Supports detailed high-frequency reproduction in a compact installation.
• Integrated 6 dB Crossover: Directs high frequencies to the tweeter without a separate crossover box.
• Graphite-Reinforced Polypropylene Cone: Provides a durable woofer cone for everyday vehicle use.
• Rubber Surround: Helps support controlled cone movement and long-term durability.

Design & Installation

The PRXP3 uses a graphite-reinforced polypropylene cone, rubber surround, 7-ounce magnet, and low-profile point source tweeter. Its compact frame measures approximately 3.421 inches wide by 3.421 inches long. Grilles are not included.

Check for a 3.187-inch mounting cutout and at least 1.5 inches of top-mount depth before ordering. The speaker is rated at 4 ohms and 15 watts RMS per speaker, so it should be connected to a compatible factory-radio or amplifier channel. Vehicle-specific brackets, wiring adapters, or mounting hardware may be needed depending on the application.
