Neumann KH 310D
Product Code: KH310D
Neumann KH310D

The KH 310 D three-way active tri-amplified monitor features a Mathematically Modeled Dispersion™ Waveguide (MMD™), flexible acoustical controls, various input options (analog and digital) and an extensive range of mounting hardware. This allows the loudspeaker to be used in diverse acoustical conditions, with any source equipment and in a wide variety of physical locations. The KH 310 represents the latest in acoustic and electronic simulation and measurement technologies to ensure the most accurate sound reproduction possible.The KH 310 D is designed for use as a near-field monitor, as a front loudspeaker in mid-sized multi-channel systems, or as a rear loudspeaker in a larger multi-channel system. It can be used in project, music, broadcast centers, OB vans, and post production studios for tracking, mixing, and mastering.
Product Feature Benefit to the Customer
Powerful alloy fabric dome
Low-distortion high-frequency reproduction
Elliptical Mathematically Modeled Dispersion™ (MMD™) waveguide, with wide horizontal and narrow vertical dispersion
 
Smoother off-axis response,
More forgiving of diverse acoustical environments
Freedom of movement across the mixing console 
Reduces reflections off the mixing console
New in-house simulated drivers
Latest modeling techniques used to minimize non-linear (intermodulation) distortion
Fabric dome, neodymium magnet, midrange driver
Dedicated driver reproduces important midrange frequencies, which is especially important for speech and vocals
Light weight dome has better transient response and less breakup modes than cone designs
High power magnet reduces harmonic and intermodulation distortion
Long throw composite sandwich cone bass driver with Extremely Linear Force Factor™ (ELFF™) and ribbed surround
Damping of break-up modes and low distortion at high sound levels
Linear pistonic motor gives a very low harmonic distortion even at high excursions
Reduced radial break-up modes on the ribbed surround
Two-color + dimmable Neumann logo
