About the Alpine SPS-690A
Alpine's S-Series speakers feature rugged looks and tough, ultra-rigid cones that hit hard. The 3-way SPS-690A 6"x9" speaker delivers the bass-rich output you crave with its aluminum-coated polypropylene cone and durable rubber surround.
The titanium-coated polyetherimide (PEI) dome tweeter produces sharp details across a wide dispersion pattern, for excellent "sweet spot" imaging. A pulp cone midrange adds warmth and texture to the output from this well-balanced 6"x9" speaker. Grilles are included.

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.
Pulp Cone Midranges: Each speaker has a 2-3/8" pulp cone midrange.
Titanium-coated PEI Dome Tweeters: Each speaker has a 1/2" titanium-coated PEI 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.
