Neumann KH 420 overview

  • 1Description

The KH 420 from Neumann is a three-way active monitor designed for use as a mid-field or main monitor, and can be used free-standing or flush mounted into a wall. It is particularly well-suited for use in music, broadcast, and post production studios for tracking, mixing and mastering, and in multi-channel systems can be mixed freely with other loudspeakers in the range.

In-house computer optimized drivers, a waveguide featuring Mathematically Modeled Dispersion (MMD), flexible acoustical controls, various input options and an extensive mounting hardware range allow the KH 420 to be used in diverse acoustical conditions, with any source equipment, and in a wide variety of physical locations.

    Neumann KH 420 reviews

    KH 420 - 3-Way Active Studio Monitor is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Neumann KH420, KH310 The large KH420 as well as its junior brother, the KH310, create a remarkably clean sound. They are scientifically designed by real audio engineers in Germany and offer the recording engineer or producer an extremely accurate sound. (What else would you expect from Neumann?) They are tri-amped speakers with very sharp digital 24db/octave crossovers The electronics (3 channels per speaker) are built in. All the speakers need is a line level, balanced input, such as you can easily get from the likes of a Grace m920 or M905, or just board out. The KH420's are designed for normal listening at a distance of 5 to 10 feet. The smaller KH310's do just as well sonically but they are intended to be closer to the listener's ears, say 3-5 ft. as they would be sitting on a console's meter section. The commenter has a pair of EACH of the speakers, so he knows first hand what he is describing. They are simply the very, very finest speaker systems I have heard in over 50 years of critical listening. They are pure gold. They are just super delicious to hear. Toss your hifi speakers out the window and upgrade to these very professional speaker systems. They are worth every penny, and you will never regret buying them. Just be certain you have an extremely clean signal to feed to them. Any sonic defects in source material will instantly be revealed. Not for the faint of heart!
