A titanium-coated PEI dome tweeter produces sharp details across a wide dispersion pattern, for excellent "sweet spot" imaging. The SPS-460A also fits in metric 4"x6" openings. Grilles are not included — factory grilles are appropriate 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.

Titanium-coated PEI Balanced-dome Tweeters: Each speaker has a 7/16" 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.

Mounting: The speakers can be mounted in a metric 4"x6" opening, or, using the supplied adapter rings, the speakers can be mounted in a U.S. standard 4"x6" opening. The Crutchfield database contains the measurements of the speakers using the adapter rings in a U.S. standard 4"x6" opening. When used without the adapter rings in a metric 4"x6" opening, the speakers have the following measurements:

  • Depth as top: 1.754"
  • Mounting height: 0.184"
  • Flange height: 0.029"
  • Depth as bottom: 1.783"
  • Tweeter protrusion: 0.155"
