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 7/16" 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.
