This level of precision ensures exceptional stereo imaging and balance for critical recording applications.
The Mini K87’s specially tuned K67/K87 style capsule is supported by a custom circuit, designed to enhance and complement its performance. This results in a smooth, neutral response with a full low frequency presence, making it an excellent choice for professional and home studio environments alike.
