Powered 3-way Studio Monitor 800W with 10" Woofer, 3" MF Driver and 1" Tweeter
The KH 420 represents the result of using the latest techniques in acoustical, electronic and mechanical design to bring a new benchmark in audio reproduction quality. 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.
The KH 420 can be used free-standing or flush mounted into a wall, and, in multichannel systems, can be mixed freely with other loudspeakers in the range.
Caractéristiques
Computer mechanically modeled three-way cabinet design using Low resonance Integral Molding (LRIM) materials
New in-house simulated magnetically shielded drivers
For safe use near magnetic storage media
Robust against accidental physical damage
Light weight dome has better transient response and less breakup modes than cone designs
High power magnet reduces harmonic and intermodulation distortion
Reduced air noise and improved rocking modes
No coloration from organ pipe resonance
More forgiving of diverse acoustical environments
Freedom of movement across the mixing console
Reduces reflections off the mixing console
Dimmable for low lighting level conditions or behind the screen applications
Repeatable acoustical settings after moving loudspeakers
Dual supply improves transient response
Mechanically compatible with O 410, KH 870 and O 870
Easy advanced planning for installations
