Bold Bass. Built to Dominate — This is the FXB121VA

When you crave bass that doesn’t just fill your cabin — but owns it — the FXB121VA answers with brute force and finesse. This 12-inch active subwoofer blends powerful Class D amplification with an acoustically tuned ported enclosure, engineered to shake the silence and elevate every track into a pulse-pounding ride.

  • Relentless Built-In Power: With 300 watts RMS and 600 watts of peak output from an efficient Class D amplifier, the FXB121VA delivers low-end impact that’s clean, commanding, and absolutely uncompromising — even when the volume pushes the limit.
  • Durability Meets Definition: A Black Polypropylene Mica cone backed by a laminated butyl rubber surround ensures detailed, responsive bass — strong enough to handle your hardest drops, yet refined enough to bring out subtle textures and tonal warmth.
  • Ported to Perfection: The trapezoidal enclosure features a precision-tuned bass reflex port, enhancing airflow and boosting sub-bass extension. The result? Deeper, tighter, and more dynamic bass that breathes life into every genre.
  • Smart Control, Clean Integration: With RCA inputs, a 30–150Hz adjustable low-pass filter, and a built-in 25A fuse, the rear control panel gives you everything you need to shape your sound with surgical precision — all while preserving signal clarity.
  • Space-Conscious Powerhouse: At 17.8 x 14.96 x 11.8 inches, the FXB121VA fits comfortably into most trunks without sacrificing acoustic performance — wrapped in rugged black carpet for a stealthy look that complements any setup.
  • Engineered for Maximum Output: A 2-ohm impedance and high 93dB sensitivity ensure this sub plays loud, hits hard, and integrates seamlessly into your existing system — letting your bass do more with less.

For those who demand bass with presence — not just volume — the FXB121VA is more than a subwoofer. It’s a statement. A foundation. A force. Power up, turn it loose, and drive with sound that moves more than air — it moves you.
