HCC5768CX

The Hifonics HCC5768CX is a pair of 5x7 / 6x8-inch two-way coaxial speakers from the COLOSSUS Classic line, cut to fit both of the common oval openings used in trucks, SUVs, and many domestic sedans. Each speaker handles 65W RMS and 125W peak, the highest ratings in the Classic coaxial range, with 88dB sensitivity.

A 1-inch aluminum dome tweeter at the center of the cone extends the top end and keeps detail present at highway speed. The lightweight blue woven fiber cone reacts quickly through the midrange, and a butyl rubber surround adds real mid-bass output while resisting heat and time. A passive Butterworth crossover at 6kHz with a 12dB slope keeps the transition between elements clean.

A pure copper voice coil on a Kapton former sheds heat, an epoxy-infused natural fiber spider keeps the cone centered under power, and the over-coil cooling system exchanges air across the coil through the spider. A ferrite magnet supplies motor force in a compact package, and an anti-resonant stamped steel basket keeps the frame from adding distortion of its own.

Mounting uses a 5.67in cut-out with an 8.60in x 5.56in outside diameter and 2.13in of depth, shallow enough for most factory door and rear deck positions. Frequency response runs 80Hz to 20kHz. Grilles are not supplied, since these usually mount behind a factory panel. The pair weighs 4.2 lb.
