Neumann KH 310 L Active, Tri-Amplified Three-Way Midfield Studio Monitor, 1?€? / 3?€? / 8.25?€? Left

With its specially designed midrange driver, the compact KH 310 is particularly suited for precise work with speech, vocals, guitars and other instruments that have a midrange emphasis. Its closed design enables a very fast transient response. The associated low harmonic distortion guarantees a neutral reference sound to meet the highest standards.
