Memphis Audio PRX57

The Memphis Audio PRX57 is a pair of 5-by-7-inch two-way Power Reference coaxial car speakers. A PEI dome tweeter, graphite-reinforced polypropylene cone and butyl rubber surround form the integrated speaker assembly. The multi-direction pivot tweeter provides adjustable orientation during setup, while an integrated 6 dB crossover handles the tweeter signal.

Memphis lists 40 watts RMS and 80 watts peak power handling, 88 dB sensitivity and a 2.125-inch mounting depth. The speakers have a 4-ohm impedance. Grilles are not included. Verify the mounting opening, screw pattern, rear clearance and wiring for your vehicle before installation. Allow room for the tweeter beneath factory trim and confirm whether vehicle-specific brackets or adapters are required. Match the source unit or amplifier to the speaker specifications.
