October 4, 2017


Oklahoma City, OK, Oct 4, 2017 — DD Audio announces the expansion of their E Class Speaker line with the release of the EX4 Coaxial. The EX Coaxial Series now consists of a 6.5″, 6″x9″, 5″x7″, 5.25″, and 4″ options. There will also be a 2.75″ option released later this year.

The EX4 has a shallow mounting depth (1.85″) and includes a 4″x6″ adapter plate allowing it to easily drop into both 4″ and 4″x6″ factory locations. This makes the EX4 a very versatile speaker able to be used in everything from late model GM pickup trucks to newer BMWs.
