The world’s most advanced audio system, Sphere Immersive Sound, will debut at Radio City with the 2025 Christmas Spectacular Starring the Radio City Rockettes.

Sphere Immersive Sound uses next-generation 3D audio beamforming and wave field synthesis technology to transform how audio is delivered. The result is controlled, consistent, and crystal-clear audio for audiences – whether you’re in the front row of the orchestra or the back of the third mezzanine, the audio experience, including the volume, is the same. Consistent audio levels from point of origin to destination provides each audience member with an exceptional listening experience – it’s headphone-quality sound without the headphones. With more than 7,000 individually amplified loudspeaker drivers, this technology will substantially improve the audience experience at Radio City, and provide artists and engineers with greater programming control and flexibility – including the ability to spatialize audio, sending different sounds to distinct points in the theater. 

As the first event to utilize Radio City’s new Sphere Immersive Sound system, the Christmas Spectacular continues to push the boundaries of theatrical technology. Through Sphere Immersive Sound, guests will experience the Christmas Spectacular with a new clarity and purity of sound, fully enveloping the audience in holiday joy. The use of Sphere Immersive Sound for the Christmas Spectacular is the most recent example of the technological innovations that the production has embraced – from holographic imagery to projection mapping to flying Frost Fairy drones.
