„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.).

Further enhancing its appeal, the NHT IW4 employs high-quality crossover components to ensure that the transition between the woofer and tweeter is smooth, minimizing phase issues.
