Overview

Our take on the Alpine SPS-1629S

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.

The woofer cone on the SPS-1629S 6-1/2" speaker adds hefty bass hits to the 3/8" tweeter's sparkling highs. An air-injected rubber surround resists harsh environmental conditions. 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 3/8" 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.
