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.\u003cbr\u003eThe KH 420 has been designed for use as a mid-field or main monitor. It is particularly well-suited for use in music, broadcast, and post production studios for tracking, mixing, and mastering. 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.\u003cbr\u003e\n\u003cp\u003e\u003cbr\u003e \u003c\/p\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp\u003e\u003cstrong\u003eAcoustics\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp\u003e−3 dB free field frequency response\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e26 Hz - 22 kHz, ± 3 dB\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp\u003ePass band free field frequency response\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e28 Hz - 20 kHz, ± 2 dB\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp\u003eSelf generated noise level at 10 cm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e\u0026lt; 20 dB(A)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp\u003eTotal harmonic distortion \u0026lt; 0.5 % at 95 dB SPL at 1 m\u003c\/p\u003e\n\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e\u0026gt; 120 Hz\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003cp\u003eMax.

General Description

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 has been designed for use as a mid-field or main monitor. It is particularly well-suited for use in music, broadcast, and post production studios for tracking, mixing, and mastering. 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.
