  • Developed for HARMAN Professional Solutions, this technology ensures every listener in the room enjoys the same exhilarating sound experience via precisely-tuned beam-forming components. HARMAN’s revolutionary technology uniquely unites 24 precisely calibrated 1.25” transducers in each of the elegant Radiance speakers to deliver the same superior sound coverage from corner to corner. 
  • Harman Kardon Radiance 2400 uses patented Constant Beamwidth Technology (CBT) with 24 drivers to create an all-new listening experience. Typical loudspeakers have very narrow sound dispersion in the mid-range and high frequencies, making a very narrow sweet spot for one listener. On the other hand, CBT delivers room-filling sound dispersion and a resulting wide sweet spot, so everyone in the room has great listening experience. The use of CBT allowed us to reduce the cabinet size dramatically. This resulted in a very sleek loudspeaker that does not compromise on sound but looks even better when compared to bulky wooden floor-standing speakers in combination with large AV components.
  • Close and restart the Google Home app, or restart your phone. Start the Google Home app again, and the speaker should now appear.
