  • General
  • Feature
  • Specification
ATEÏS GB20T is a refined spherical omni-directional loudspeaker system finished in white, and with a diameter of just 10”. This decorative system has a 20-watt, 8” treated twin-cone loudspeaker, protected with an opaque dust screen. Omnidirectional in design, it exhibits a true 360-degree angle of coverage in the horizontal plain. All ATEÏS loudspeakers have undergone tough testing procedures to ensure that all products can operate at their rated power in compliance with IEC 60268 part 5. In addition, all the fire-rated products have undergone actual fire tests to ensure compliance with BS5839 part 8. The GB20TC is tested in accordance with IEC 60268 part 5 for high quality intelligibility. The lsquo;C’ version complies with BS5839 part 8, and is hence fitted with ceramic terminal and thermal fuse.
