Neumann KH 310 A G

EXPANDED MIDRANGE PRECISION – DRY BASS SOUND
The KH 310 is designed with a midrange driver ideal for precise work with speech, vocals, guitars, and other midrange-emphasized instruments. Its closed design enables a fast transient response, while low harmonic distortion guarantees a neutral reference sound to meet the highest standards.

The KH 310 is a three-way, tri-amplified monitor featuring thermally protected Class AB amplifiers (210 W and two times 90 W). The Mathematically Modeled Dispersion™ (MMD™) waveguide delivers sound waves with superior accuracy. Drivers are modeled using Neumann’s in-house developed software, reducing non-linear distortion. The controlled dispersion characteristics optimize reproduction in various room configurations with adaptable acoustical control settings.
