Hertz DCX 690.3 - Pair of 6x9 coaxial speakers, 3-way 180w grids

Article Code: DCX 690.3

A true 3-way coaxial capable of reproducing a wide frequency spectrum.

DCX 690.3 car coaxials use an oversized magnetic assembly, TPU (thermoplastic polyurethane) surround,

a 60 mm diameter midrange and a PEI dome tweeter.

The result is linearity, wide dispersion and extra-ordinary efficiency not found in traditional coaxial components.

An engaging, emotional sound, even at high SPL levels
