The AT-09 is a passive fullrange speaker for fixed installations. It impresses with its high performance capacity, compact dimensions and directed dispersion characteristic.
In addition to outstanding technical features, the models of the Arc series are generally characterized by their attractive design.

Main features

  • 2 × 6.5" / 1" compression driver on rotatable CD horn, electronic high frequency protection
  • Nominal power rating: 200 watts at 8 ohms
  • Dispersion: 90 ° × 40 ° (H × V)
  • SPL max.: 125 dB
  • Dual connection panel: Speakon and 4-pole connector (inside, with cable outlet)
  • High-quality wooden enclosure (multiplex birch)
  • Available in RAL Classic, NCS or Pantone colors on request
  • Optionally available with weatherproof PU coating
  • Various mounting options
  • In order to ensure performance and operational safety, Fohhn system amplifiers including the correct speaker preset are required.
