The Memphis Audio PRXP4 is a pair of 4-inch, 2-way coaxial car speakers from the Power Reference series, engineered for direct factory replacement and tight OEM installations. It features a low-profile "Point Source" tweeter design that sits flush to avoid interfering with factory speaker grilles.
Product Description & Design
-
Low-Profile Point Source Tweeter. The silk dome tweeter is recessed within the woofer structure rather than protruding outward. This allows the speaker to fit cleanly behind tight factory dash or door grilles without modification.
-
Audio Profile & Materials. A graphite-reinforced polypropylene cone paired with a durable rubber surround delivers warm, balanced midrange and controlled cone movement. The silk dome tweeter produces smooth, natural high frequencies.
-
System Integration. With a 20-watt RMS power rating and a 4-ohm impedance, the PRXP4 works efficiently whether powered by a factory head unit or an aftermarket amplifier. An integrated 6dB crossover separates frequencies between the woofer and tweeter for accurate sound reproduction.
