ZS4CX 2-Pack

Two full pairs of Hifonics Zeus ZS4CX 4-inch coaxial speakers bring four matched drivers into one order, totaling 700 watts of peak handling across the set for covering front and rear 4-inch locations together. Each speaker uses a Neo-Mylar soft dome tweeter for clear, impact-resistant highs and an Alpha-Cellulose cone that stays light for quick midrange response while remaining rigid enough for deeper bass. A moisture-resistant rubber surround adds mid-bass impact and resists the humidity that builds up inside a door panel over time. A pure copper voice coil on a Kapton former builds a strong magnetic field while shedding heat, and braided tinsel leads stay flexible during sustained high-power playback. The passive Butterworth crossover handles the split between tweeter and woofer without extra hardware, and the anti-resonant stamped steel basket keeps the frame rigid so output stays clean at higher volumes instead of flexing. Rated for 30 watts RMS and 175 watts peak per speaker, these coaxials handle factory power easily and have room to grow with an amplifier later. They install behind a panel or dash since they ship without grills, and spade connectors keep wiring simple. Two matched pairs mean front and rear channels finally sound the same instead of an old factory speaker paired against a new one.
