Description

Product Overview

The Massive Audio FC6X 6.5" coaxial speakers bring integrated midrange and treble into one compact speaker. A woven fiber paper cone, 20mm silk-diaphragm tweeter and built-in 6dB crossover shape the package for car audio installations.

Key Features & Benefits

  • Woven fiber cone: Its low-mass construction supports fast response and accurate midrange.
  • Silk-dome tweeter: The 20mm tweeter uses ferro fluid and provides high-frequency response with off-axis extension.
  • Integrated crossover: The built-in 6dB crossover combines the speaker’s high- and low-frequency drivers in one unit.
  • Durable construction: A powder-coated, heavy-gauge steel basket and Butyl rubber surround are designed for mobile environments.
  • Customizable grilles: Two-piece paintable metal grilles let you coordinate the speaker finish with your vehicle interior.
  • Isolated leads: Fully isolated tinsel leads help preserve stereo imaging.
