Memphis PRXP4 4" 2-Way Coaxial Speakers

The Memphis PRXP4 is a pair of 4-inch, 2-way coaxial car speakers designed for compact factory speaker locations. It provides a direct replacement option when an original speaker has failed or no longer delivers clear, balanced sound. Its shallow profile helps address installations where grille clearance is limited.

These speakers are intended for vehicles that use 4-inch speaker positions, subject to confirming the mounting opening and available depth in the vehicle. The PRXP4 uses a point source tweeter arrangement to keep the coaxial assembly low in height. This makes it a practical option for many factory-style installations with retained trim panels or grilles.

A silk dome tweeter handles high-frequency detail, while the graphite-reinforced polypropylene cone is paired with a rubber surround. This combination is designed for controlled cone movement and long-term durability in a vehicle environment. The result is a smooth, warm-leaning character suited to everyday listening.

The integrated 6 dB tweeter crossover directs appropriate high frequencies to the tweeter within the speaker assembly. This built-in design simplifies installation compared with systems that require separate passive crossover boxes. The low-profile point source tweeter is the central engineering feature, helping preserve clearance without adding a separate tweeter location.

With a 4-ohm nominal impedance and 20-watt RMS power handling per speaker, the PRXP4 can be used with compatible factory head units or modestly powered aftermarket amplification. It is best matched to installations that prioritize fitment, clear upper-frequency reproduction, and a compact coaxial design. Verify vehicle-specific fitment, mounting depth, and wiring connections before installation.

Key Features

• 4-Inch Coaxial Design: Combines woofer and tweeter in one compact speaker assembly.
• Point Source Tweeter: Low-profile layout helps preserve factory-grille clearance.
• Silk Dome Tweeter: Supports smooth and detailed high-frequency reproduction.
• Integrated 6 dB Crossover: Directs high frequencies to the tweeter.
• Reinforced Polypropylene Cone: Provides a durable, lightweight woofer diaphragm.
• Rubber Surround: Supports controlled cone travel and durability.

Design & Installation

The PRXP4 uses a graphite-reinforced polypropylene woofer cone, rubber surround, silk dome tweeter, and 8-ounce magnet. Its 2-way coaxial layout places the low-profile point source tweeter at the center of the woofer. The speaker has a 1.75-inch top-mounting depth for compact installation spaces.

Confirm that the vehicle accepts a 4-inch speaker and has at least the required mounting depth before ordering. Match the speakers to a compatible 4-ohm factory or aftermarket audio system and observe the 20-watt RMS rating per speaker when selecting amplification. Use vehicle-appropriate mounting hardware and adapters where required, as fitment varies by vehicle.
