About the Alpine SPS-5729

Superb sound and sturdy construction! Alpine S-Series speakers deliver high-quality, reliable performance in a durable package. The hybrid pearl-mica injection poly woofer cone is strong and lightweight for extended low-frequency reproduction — it's geared to handle the bass-rich output of Alpine's Bass Engine®-equipped receivers. The I-Drive low distortion circuitry improves the woofer's response, increasing low-end output while limiting distortion. Luminous high frequencies flow from the titanium-coated balanced dome PEI tweeter.

Product Research

Features

Woofers: Each speaker features a hybrid pearl mica injection polypropylene woofer cone. Mica adds strength and heat resistance to polypropylene, resulting in reduced distortion and improved reliability.

Surrounds: For a smoother response and improved durability, the woofers use air-injected rubber surrounds.

Tweeters: Each speaker has a 9/16" PEI and titanium 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.

I-Drive Design: The low distortion magnetic design provides better woofer control and smoother bass and midrange.

Bass Engine Ready: These speakers are Bass Engine Ready, meaning they can be paired with Bass Engine Equipped head units and Bass Engine Ready subwoofers to create a complete sound system that can be totally personalized.

Mounting: The speakers can be mounted in a 5"x7" opening, or, using the supplied adapter rings, the speakers can be mounted in a 6"x8" opening. The Crutchfield database contains the 5"x7" measurements. When mounted in a 6"x8" opening using the adapter rings, the speakers have the following measurements:

  • Depth as top: 1.96"
  • Mounting height: 0.552"
  • Flange height: 0.552"
