The E Series 4 inch Coaxial is perfect for the listener who wants to instantly take their system from factory to fantabulous. This 2-way set is designed for efficiency with features that deliver outstanding sound and value. Included in the box is a 4 inch to 4×6 inch adapter plate allowing the EX4 to mount perfectly into factory 4×6 inch locations.


The EX4’s woofer features an injection molded poly cone, rubber surround, and rigid steel frame. For reduced inductance, extended high-frequency roll off, and increased efficiency the voice coils features a double slit former and the motor utilizes a copper pole cap. The soft parts are driven with a high flux 11 Oz ferrite magnet motor.


The 20 mm high-grade neodymium driven mylar dome tweeter is able to easily and cleanly reproduce the upper-frequency range needed to bring out the subtle details in your music.
