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.

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.
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.

These speakers were bought to replace my factory speakers in my Monte Carlo while still using the factory amp. These speakers sound excellant. Sound is very clear and accurate. Great highs and midrange. I would highly reccomend. John
