Focal

Our take on the Focal Access 30 A1

Focal Access subs emphasize faithful delivery of your music's fundamental frequencies. They feature all-weather woven glass-fiber cones with butyl rubber surrounds for outstanding strength, durability, and musical accuracy. Tough 4-layer voice coils with self-regulated cooling ensure reliable power handling.

The Access 30 A1 12" sub handles up to 250 watts RMS, and features a massive magnet for powerful, reliable output. Focal designs this 4-ohm sub to work best in ported enclosures for dynamic response that brings out the full impact of your music's low end. The included gasket provides a clean look to your installation and eliminates air leaks from your enclosure which can lead to unwanted distortion.

Highlights:

  • 12" 4-ohm subwoofer
  • woven fiberglass cone with butyl rubber surround
  • non-resonant ABS/fiberglass basket

  • peak power handling: 500 watts

The type of bass you get from your component subwoofer doesn't depend on the woofer alone. You'll need a strong, tightly constructed enclosure for optimum subwoofer performance.
