SPS-400 - Alpine Type-S 4" 2-way car speakers

Description:

Alpine combines outstanding materials with superior construction to create their Type-S Series speakers. Upgrade your factory speakers with these Alpines, and they'll fill your vehicle with high-fidelity sound at a reasonable cost.

The SPS-400 4" speakers use strong, lightweight polypropylene-mica woofers to handle the lower frequencies. Air-injected rubber surrounds keep cone movement under tight control, eliminating distortion and enhancing bass. Stamped steel frames provide rugged support for these speakers, and their low profile allows them to fit in more factory locations.
