Our take on the NHT iW4

by Marshall Chase

25 years of audio know-how in every architectural series speaker

NHT is renowned for their excellent-sounding speakers. Even their name invites you to "Now Hear This". The iW4 packs a top-notch three-way speaker system into a discreet package to weave a tapestry of sound filled with rich detail. You get a 3/4" tweeter, a 2" midrange, along with dual 5-1/4" long-throw woofers. This combination puts you right in the sweetspot of dynamics and depth, whether you're listening to choice music selections or enjoying your favorite movie sound tracks.

Outside-the-box thinking

The iW4 drivers are mounted in a low-resonance wooden frame baffle. It's like having an in-wall bookshelf speaker. Moisture resistant materials and tight gasket covers let you install these speakers in any room in the house, including kitchen and bath, with confidence. The spring-loaded mounting cams help ensure that the iW3s will install firmly without coming loose or cracking the surrounding drywall over time, so you can expect years of fine performance. Just prepare the opening in your wall and run UL-rated wiring from your receiver and you can secure this flush-mount speaker with a few turns of a screwdriver. And you can paint the white matte grilles to match any dècor.

An iW4B pre-construction bracket is included and recommended for installing the iW4 in a home with new construction.

Features

Overview: The NHT iW4 in-wall loudspeaker is designed to deliver refined, musical, bookshelf speaker-like sound from and attractive, unobtrusive in-wall speaker. The iW4 in-wall loudspeaker offers extreme detail, excellent bass, wide dynamics, and high output. The NHT iW4 is useful in almost any distributed sound application, from home music, home theater, office, or commercial installations. It is suitable for the highest performance home theaters, high-end stereo systems, dens, dining rooms, master bedrooms, where high-quality sound is desired.

3-Way Design: The NHT iW4 uses two 5.25" long-throw polypropylene woofers, a 2" aluminum dome midrange, and a .75" aluminum dome tweeter. The midrange has its own internal chamber reducing comb filtering and improving detail. The advantage of a dual-woofer 3-way design is low distortion and wide dispersion, changing the sweet "spot" to a sweet "room" for listening

Acoustical Waveguide: The iW4's tweeter & midrange utilize an acoustical waveguide to deliver, more even high frequency response, no matter what part of the room you're in.

Crossover Network: The in-wall loudspeaker features a 3-way crossover network.

  • low pass & high pass at 750Hz (18dB/oct)
  • high pass & low pass at 5kHz (18dB/oct)

Non-Resonance Baffle: 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.

Spring Post Terminals: The in-wall speaker features gold-plated, spring-post terminals which will maintain contact with the speaker wire over the life of the installation.

Note: 16-AWG, 2-conductor in-wall speaker wire is recommended for runs of 10 feet or less, with heavier gauge cable used for longer runs.

Installation

Flexible Mounting System: The mounting assembly is designed to be intuitive and flexible, making it ideal for new or existing construction. The iW4 in-wall speaker's included mounting bracket allows for retrofit and pre-construction installation. Mounting hardware (screws, wings) is supplied.

Note: The NHT iW4B pre-construction in-wall bracket (228IWB4) is included with the NHT IW4 in-wall speaker, or sold separately if intended to be used to frame out the in-wall speaker location prior to sheetrock application.

Horizontal/Vertical Mounting: The iW4 in-wall speaker can be mounted in the wall either horizontally or vertically.

Cut-Out Template: A convenient template for the in-wall speaker's cutout is included to make installation location and retrofit cutting easier.

Paintable: The iW4 is painted with a neutral white primer and may be painted to match your wall decor with typical latex paints. When painting, the grille and speaker frame is painted separately. A convenient paint shield is included to protect the drive units in the speaker frame.

Note: Do not attempt to paint the black baffle surface (which houses the drivers). Its black finish prevents the speaker's black drivers from being visible once the grille is attached.
