Memphis PRX46 4x6" 2-Way Coaxial Speakers

The Memphis PRX46 is a pair of 4x6-inch, 2-way coaxial car speakers designed for replacing or upgrading compatible factory speaker locations. Its compact format helps address the limited space often found in dash, door, or rear-deck 4x6-inch applications. Each speaker combines a woofer and tweeter in one assembly for straightforward full-range speaker replacement.

With 30 watts RMS and 60 watts peak handling per speaker, the PRX46 is suited to modest-power car audio systems. Its 4-ohm impedance supports use with compatible factory or aftermarket audio equipment. The 86 dB sensitivity rating and 125 Hz to 20 kHz frequency response define its published operating specifications.

The speaker uses a polypropylene woofer cone with a polyurethane surround. This material combination is intended to provide a durable moving assembly for midrange and upper-bass reproduction. A PEI dome tweeter handles higher-frequency content within the coaxial design.

A multi-direction pivot tweeter system lets the installer aim the tweeter during installation. This can be useful when the speaker location is off-axis from the listening position. The integrated 6 dB tweeter crossover is designed to direct appropriate frequencies to the tweeter.

The PRX46 is part of the Memphis Audio Power Reference speaker line and can be used as a focused factory-speaker replacement or as one part of a broader vehicle audio upgrade. Its 2.125-inch mounting depth should be checked against the available depth behind the intended mounting surface. Installation hardware and short speaker leads are included, while grilles are not included.

Key Features

• 4x6-Inch Coaxial Format: Combines woofer and tweeter in a compact speaker assembly.
• 30W RMS Per Speaker: Supports compatible moderate-power factory or aftermarket systems.
• Pivoting PEI Dome Tweeter: Allows high-frequency output to be aimed during installation.
• Polypropylene Woofer Cone: Provides a durable cone material for full-range playback.
• Polyurethane Surround: Supports controlled cone movement and durability.
• Integrated 6 dB Crossover: Routes high-frequency content to the tweeter.

Design & Installation

The PRX46 uses a black-on-black M-Cone appearance, a polypropylene woofer cone, polyurethane surround, PEI dome tweeter, and an 11-ounce magnet. Its 2-way coaxial layout places the tweeter within the woofer assembly, reducing the need for separately mounted external tweeters. Grilles are not included.

Confirm the vehicle's 4x6-inch speaker opening, mounting pattern, and available 2.125-inch mounting depth before ordering. The package includes two speakers, two 12-inch speaker leads, eight 1-inch screws, eight speed clips, and a user manual. For amplified systems, match the amplifier setup appropriately to the speakers' 4-ohm impedance and 30-watt RMS-per-speaker rating.
