Key Features & Benefits

  • Three-way design: A midrange and tweeter join the main speaker for a more complete, balanced presentation.
  • Light, rigid cone: The vacuum polypropylene cone supports cleaner midbass with reduced cone flex during dynamic playback.
  • Rubber surround: The flexible edge tolerates road vibrations and helps maintain accurate cone movement.
  • Integrated tweeter crossover: It directs the appropriate high-frequency signal to the tweeter, helping keep highs clear at higher listening levels.
  • Finished installation: Grilles and mounting hardware are included for a clean appearance and driver protection.

Why Choose This Product?

The R165X3 pair brings a three-way design and Rockford Fosgate sound to a factory-speaker replacement project. Its stamped steel basket resists deformation under cabin vibrations, while the included grilles help give the installation a neat, finished look.

With a 52 Hz lower frequency limit, the speakers provide usable low end for everyday listening. Their stated power handling and sensitivity also give you concrete figures to compare when planning a system.
