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.Was this helpful?
