  • It is not possible to connect further speakers (center or rear) to the system.

    The Harman Kardon Radiance 2400 is a 2.1 sound system. With it's unique sound characteristics and sound dispersion, it can fill a large room with high quality sound. 
  • It is possible to connect a turntable to the AUX input of the Radiance 2400. Depending on the turntables output specifications, a phono-preamplifier will in most cases be necessary to connect in-between.

  • 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.
