Memphis PRX46

The PRX46 is a 4″×6″ 2‑way coaxial speaker from Memphis Audio’s Power Reference (PRX) line. It’s designed to upgrade factory audio systems with balanced sound and a compact footprint. The woofer uses a graphite-reinforced polypropylene cone for strength and lightness, while the PEI dome tweeter is pivot‑mounted to allow for better imaging. With a polyurethane surround and integrated 6 dB crossover, it delivers warm, clear sound suited for OEM-style installations.
