About the Alpine SPS-170A
Alpine's S-Series speakers feature rugged looks and tough, ultra-rigid cones. The SPS-170A 6-1/2" speaker pumps out heavy bass output with its aluminum-coated polypropylene cone and durable rubber surround.
A titanium-coated PEI dome tweeter produces sharp details across a wide dispersion pattern, for excellent "sweet spot" imaging. You can swivel the titanium-coated PEI balanced dome tweeter up to 15° to fine tune high-frequency focus.

These speakers r the best speakers i ever owned. These speakers sound like infinity sound but with a lower price tag. The highs sound clear and low sound good too.

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.
