Oklahoma City, OK, Oct 4, 2017 -- DD Audio announces the expansion of its E Class Speaker line with the release of the EX4 coaxial. The EX Coaxial Series now consists of a 6.5”, 6”x 9”, 5”x 7”, 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”x 6” 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.

The EX line drivers were designed with the purpose of providing a low cost solution for upgrading OEM or subpar aftermarket audio systems, while still performing up to the sound quality standards DD Audio is know for.

EX4 Coaxial features include:

• 4”x6” Adapter Plate
• Marine Grade
• Injection molded poly cones
• Rubber surrounds
• Rigid steel frames
• Double slit voice coil formers
• Copper shorting caps
• High energy ferrite magnet motors
• 20 mm neo driven, mylar dome tweeters
