The CT Sounds BIO-5X7-COX is a pair of 5x7-inch 2-way coaxial car speakers. They are full-range speakers that can replace factory speakers. They can run from a factory head unit, an aftermarket head unit, or a multichannel amplifier.
Each speaker pairs a 13mm silk-dome tweeter with a black vacuum polypropylene woofer cone. The surround is nitrile butadiene rubber, and the basket is stamped steel. The voice coil is a 1-inch KSV CCAW coil.
Steel plate terminals connect the speakers, with a larger terminal for positive and a smaller one for negative. CT Sounds speaker grilles, wire and screws are included.
