Neumann SBK 130 A Sound Diffraction Sphere

Enhance Your Microphone’s Directivity and Frequency Response
The Neumann SBK 130 A is a sound diffraction sphere designed to optimize the performance of the KM 183 omnidirectional microphone and other compatible KM series models. By altering the acoustic characteristics of the microphone, this precision-engineered accessory enhances directivity, allowing for improved clarity and detail in field recordings, orchestral performances, and ambient sound capture.

Designed for Professional Studio and Live Applications
This diffusion sphere is an essential tool for engineers and recording professionals looking to achieve a more natural, open sound while maintaining accuracy. Whether you are recording classical ensembles, capturing immersive room ambiance, or working on high-fidelity field recordings, the SBK 130 A refines microphone performance by increasing high-frequency presence and improving spatial imaging.

High-Quality Construction for Optimal Sound Diffraction
Crafted with precision, the Neumann SBK 130 A features a robust and acoustically transparent design that minimizes unwanted reflections while ensuring optimal sound diffusion. Its spherical shape works to modify the pickup pattern, reducing off-axis coloration while maintaining a balanced frequency response. This makes it a valuable addition to any high-end recording setup where nuanced sound reproduction is required.

Achieve a More Focused and Detailed Audio Capture
The SBK 130 A effectively increases the directivity of the KM 183 microphone by manipulating how sound waves interact with the capsule. This results in improved clarity and intelligibility, especially in distant mic placements where greater focus is needed. The enhancement in frequency response ensures a richer, more articulate recording, making it ideal for professional-grade audio capture.

Seamless Integration with KM Series Microphones
Designed specifically for Neumann’s KM 183, the SBK 130 A fits seamlessly with the microphone, providing an effortless upgrade to its performance. Its lightweight design ensures minimal impact on mic placement while delivering significant acoustic benefits. Whether used in studio environments or live sound applications, this diffraction sphere expands the versatility of your Neumann microphone setup.
