Dual 8-inch 2-way, 90° x 60° (rotatable)



  • Contemporary style, weather-resistant enclosure and components - ideal for a wide range of applications.
  • Dual 8-inch, 2-way system - in a lightweight, multipurpose enclosure featuring a heavy duty, powder coated aluminum grill.
  • Versatile mounting options - The included yoke mount bracket can be used for mounting and aiming the system in vertical or horizontal orientations. Provision for optional Omni-mount™ bracket is built in.
  • Advanced Directivity™ rotatable waveguide - (90° × 60°) enables the loudspeaker to deliver accurately focused sound, regardless of the enclosure's mounted orientation.
  • Low impedance and transformer versions - Standard 8 ohm system is selectable for passive or bi-amp operation while the AD-S282HT transformer version provides taps for both 70V and 100V distributed system use.
