  • Powerful alloy fabric dome provides low-distortion high frequency sound reproduction
  • Elliptical Mathematically Modeled Dispersion (MMD) waveguide, with wide horizontal and narrow vertical dispersion provides smoother off-axis response for more forgiving and diverse acoustic environments and reduced reflections off the mixing console
  • New in-house simulated drivers is used to latest modeling techniques to minimize non-linear (inter-modulation) distortion
  • Fabric dome, neodymium magnet, midrange driver is used to dedicated midrange driver to reproduce important midrange frequencies, which is especially important for speech and vocals with a faster transient response and less breakup modes than cone designs
  • Long throw composite sandwich cone bass driver with Extremely Linear Force Factor (ELFF) & ribbed surround provides damping of break-up modes & low distortion at high sound levels. It gives a low harmonic distortion even at high excursions with reduced radial break-up modes on the ribbed surround

The Neumann KH 310 D Left Active Studio Monitor with Digital Input and Delay 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

ISO 10534-1:1996, Acoustics – Determination of sound absorption coefficient and impedance in impedance tubes – Part 1: Method using standing wave ratio

Specifies a method for the determination of the sound absorption coefficient, reflection factor, surface impedance or admittance of materials and objects. The values are determined by evaluation of the standing wave pattern of a plane wave in a tube, which is generated by the superposition of an incident sinusiodal plane wave with the plane wave reflected from the test object.
