Neumann KH 310 A Left

This is truly a great analytical, high-end studio monitor. A beautifully defined sound with superb low end. Listen to this 3-way monitor and be convinced by the masterful combination of the electro acoustics of "Klein + Hummel" and the precision construction and electronics of Neumann. Ow yes, it's a Klundert Favorite!

The Neumann KH 310 A Left offers a very full but neutral sound and can reach frequencies up to 34 Hz at -3 dB. This results in a beautiful low end reproduction. A clear and open mid is due to a high-quality 3-inch midrange driver and there is also a 1-inch driver for the high up to 21000 Hz at -3dB.

This monitor has excellent and extensive acoustic controls that allow you to fully tune the high, mid and low to your space. The built-in tri-amp amplifier module gives an awful lot of power and has special convection cooling thanks to the hefty cooling fins on the back. With an output of 150 + 70 + 70 watts, the woofer, midrange driver and tweeter are given maximum power, creating incredible dynamics.
