Description

Product Overview

Bring clearer highs and more detailed sound to your car audio system with the Infinity BeTA BE621 6.5-inch 2-way component speakers. Carbon fiber woofers, 1-inch beryllium dome tweeters, and external crossovers give you separate woofer and tweeter paths for tuning the system to your vehicle.

Key Features & Benefits

  • Carbon fiber woofers: The cones and high-roll rubber surrounds support dynamic bass response while minimizing distortion at high volume.
  • Rigid woofer baskets: Die-cast aluminum construction helps reduce unwanted resonances for cleaner bass and more precise midrange.
  • Beryllium dome tweeters: The 1-inch tweeters extend high-frequency detail up to 40 kHz.
  • External crossovers: Select 2,500 Hz or 3,500 Hz crossover points and adjust tweeter output to suit your system setup.
  • Bi-amp capable: The crossover design supports integration with a multi-amplifier configuration.
  • Included grilles: Two grilles help protect the drivers and complete the installation appearance.
