„ „ Design
NHT loudspeakers are designed to deliver refined, musical sound from attractive and affordable packages. Our efforts are
guided by the study of human hearing and are optimized for real-world use. Every NHT speaker undergoes rigorous
testing and quality control at the factory to ensure you years of listening pleasure.
The NHT iW4's custom-designed drive units are mounted in a rigid baffle/bezel assembly designed to minimize the
audible effects of unwanted vibrations and resonance. The baffle is 18mm MDF, the same material used in high quality
box speakers. It is separated from the bezel by absorptive materials designed to prevent the coloration of critical midrange
frequencies caused by wall vibration. The mounting assembly is designed to be intuitive and flexible, making it ideal for
new or existing construction. With high performance sonics and a paintable grille and frame, the iW4 is the perfect
solution for architectural audio and home theater installations.
Caution: The iW4 should be installed by an experienced and licensed custom installation professional. Be sure that the
installer possesses sufficient skill, the proper tools, knowledge of local fire and building codes, and a familiarity with the
structure of the building (especially wall and/or ceiling materials, layouts, electrical and plumbing lines, etc.).
