Product Research

Features

Aluminum-coated Polypropylene Woofer Cones: Each speaker features an aluminum-coated polypropylene woofer. Aluminum adds strength and heat resistance to polypropylene, resulting in reduced distortion and improved reliability.

Air-injected Rubber Surrounds: For a smoother response and improved durability, the woofers use air-injected rubber surrounds.

Titanium-coated PEI Balanced-dome Tweeters: Each speaker has a 9/16" titanium-coated PEI balanced-dome tweeter. PEI (Polyetherimide) is a polymer that offers high resistance against harsh environmental extremes, superior rigidity, and sonic purity. When combined with titanium, the result is a tweeter that delivers crisp, clear highs. The tweeters are adjustable and may be swiveled 15 degrees for optimum imaging.

Adapter Rings: The supplied adapter rings allow the speakers to be installed in a standard 6-1/2" opening or an oversized GM/Chrysler 6-1/2" opening. The adapter rings have tabs that must be broken off when the speakers are mounted in a standard 6-1/2" opening.
