Frequency Response Analysis
The capsule is optimized for the vocal range between 50 Hz and 13 kHz. Low frequencies feature a gentle roll-off that prevents muddiness while retaining warmth. The midrange is smooth and stable, ensuring clear vocal body and intelligibility. A presence boost around 6–7 kHz enhances clarity, articulation, and projection in live environments, while higher frequencies gradually roll off for a warm, non-harsh tone. This tuning closely follows the tonal approach of the Shure SM58 but offers a slightly brighter presence region, making it suitable for affordable large-scale deployment without compromising vocal quality.
