Description

Infinity BeTA BE621 6.5" 2-Way Component Speakers are a high-resolution component system built for serious car-audio enthusiasts, combining aerospace-inspired BeTA design with carbon fiber woofers and a 1" beryllium dome tweeter to extend detail up to 40 kHz.

  • 6-1/2" component system with two woofers, two tweeters, and two crossovers: Separate woofer and tweeter paths improve imaging and stage depth versus a standard coaxial setup.
  • Carbon fiber woofer cone with high-roll rubber surround: Minimizes distortion at high volume and supports dynamic bass response with durability in the cabin environment.
  • Die-cast aluminum woofer basket: Adds rigidity to reduce unwanted resonances, translating into cleaner bass and more precise midrange.
  • 1" beryllium dome tweeter: Delivers extended high-frequency detail with strong damping for clear, uncolored highs up to 40 kHz.
  • External crossover, bi-amp capable, with selectable crossover points (2,500 Hz or 3,500 Hz) and adjustable output: Lets you tailor the separation between woofer and tweeter and optimize for your amplifier configuration.
  • Power handling: up to 100 W RMS (200 W peak): You can pair with capable amplification to achieve substantial dynamic range without over-stressing the drivers.
  • Frequency response: 60 Hz – 40,000 Hz: Wide range supports solid bass presence and detailed highs for a more natural overall response.
  • Sensitivity: 91 dB at 2.83V: Indicates relatively efficient output, aiding loudness with moderate amplifier power.
  • Woofer mounting depth: 2-7/8": Compatibility metric for fitment behind common door panels and mounting depths.
  • Grilles included: Protects the drivers and maintains a clean install aesthetic.
  • Warranty: 3 years

These BE621 BeTA components are designed to integrate with a multi-amplifier setup to maximize imaging, detail, and dynamic range in a premium car audio system. The combination of carbon fiber woofer cones, a rigid basket, and a high-frequency BeTA tweeter delivers precise, uncolored detail across the spectrum, while external crossovers and three-position tweeter output selectability offer practical tuning for varied vehicle acoustics. The package includes everything needed for installation and long-term reliability.
