About the Alpine SPS-57C2

Alpine's Type-S speakers combine outstanding materials and construction with an attractive price. Their efficient design provides powerful sound even when system power is low — yet beefy internal parts ensure they can handle it when you crank the volume.
Alpine Authorized Online Dealer

Alpine's Type-S speakers combine outstanding materials and construction with an attractive price. Their efficient design provides powerful sound even when system power is low — yet beefy internal parts ensure they can handle it when you crank the volume.

But powerful output doesn't count for much if you don't like what you're hearing. The SPS-57C2 5"x7" speakers are bound to please your ears — pivoting silk dome tweeters direct clear highs to your ears without a hint of harshness. The aluminum-coated woofer cones move freely in the air-injected rubber surrounds for full, strong, and accurate bass response. Grilles are not included — factory grilles are suitable for most installations.

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.

Silk Dome Tweeters: Each speaker uses a 1" silk dome tweeter for smooth high frequencies. The tweeters are adjustable and will pivot approximately 15° to optimize imaging.

Mounting Rings: Without any adapter, the speakers fit a standard 5"x7" top mount opening. One of the supplied adapter rings allows the speakers to be installed in a standard 6"x8" opening and many special Ford openings. The other adapter rings allow bottom mounting.
