Innovative Technology You Can Afford

  • Finally, a 6"x8" that fits Fords and Mazdas!

  • Exclusive Rotating Elliptical Lens focuses the tweeter's high frequency response directly to your listening position for pinpoint imaging and clear detail, even from off-axis factory speaker locations:
    • Under the REL is a 3/4" Soft Dome Tweeter for high power handling and smooth response.
    • Anti-Diffraction Tweeter Post, shaped like a funnel to minimize distorting driver "bounce back."
    • Durable Poly/Mica cone.
    • Butyl Rubber Surround beats the most extreme conditions.
    • Multi-hole mounting pattern and low profile for easy installation in virtually any location.
    • Powder-coated, anti-corrosion, reinforced steel basket and grille.

    EX3 Series Full Range Coaxial Car Speakers are the ideal combination of high technology, high performance, drop-in flexibility and price.

    Replace your factory speakers with EX3 speakers with a minimum of cutting, knuckle-banging and dash-destruction.

    Designed to boost the performance of your stock head unit (so you don't have to blow extra money on electronics) with more efficient power handling and the unique REL sound-tailoring technology. That's why EX3 Series Coaxials deliver better imaging, more balance and greater clarity.
