NHT Bookshelf Speaker Folheto

NHT, since its inception, has held to the belief that what makes a speaker high-end is real,

but what makes it expensive is not. No matter what model is right for you, be assured

it was designed with one goal... to recreate in your home the performance the artist

intended, without editorializing. After all, it is the music that matters. Enjoy.

acoustic suspension

now hear this...

NHT bookshelf speakers are acoustic suspension

designs that use nature’s perfect spring force…

air… to control the cone motion instead of a heavy,

unpredictable mechanical suspension. It takes a

little more development time and amplifier power

to do an acoustic suspension design justice, but the

greatly decreased distortion, deeper bass response,

and increased detail are well worth it.

form follows function

While the Classic series of products are certainly beautiful,

their shape is all about the business of making great sound.

The graceful cabinets place every driver into a consistent,

predictable acoustical environment. For example, variable

radius edges on the cabinet sides randomize diffraction

from the midrange and tweeter drivers, aiding the

speakers’ dispersion of midrange and high frequency sounds,

while careful placement of the Four’s built-in subwoofer

guarantees tremendous deep bass response in almost any

room.

Our cabinets are made with MDF, a board manufactured

primarily of wood residues from the production of lumber

and plywood with a low percentage of virgin tree wood.

We finish them with 7 coats of hand-finished polyurethane

applied in a “solid particle” method that’s safe for the

environment. This finish is then sealed with 2 coats of

automotive grade clear-coat to protect the finish for years.

By avoiding exotic wood veneers, and using materials such

as MDF in the construction of our cabinets, we’re not

sacrificing scarce natural resources to make acoustically

sound, furniture grade cabinets.

smarter parts

By using two low distortion drivers mounted

close together on a single plate, we are able to

produce a speaker with a larger listening area,

lower distortion, and higher power handling than
previous 2-way designs.

All of the 5.25” and 6.5” woofers in the Classic

line feature frames made from BMC (Bulk Molding

Compound). Usually a designer has to choose

between inexpensive, mechanically sound materials

such as ABS plastic and stamped steel, or expensive

materials such as cast aluminum or magnesium

that are ideal acoustically and mechanically. BMC

gives us the best of both worlds: a cost effective

material that is immensely stiff, and easily shaped

into acoustically ideal shapes.

A subwoofer is the most difficult speaker in your

system to find a home for. Subwoofers are often

placed where they look best in the room, not

where they sound best. Placement in a corner

can make the bass boom while moving it away

from the walls can rob your system of the deepest

bass. With NHT’s exclusive Boundary EQ control

placement and performance can finally coexist.

a better center

While small, 2-way three-driver center speakers

are very popular, this design is really more about

creating a low profile speaker than one that’s

suited for center channel use. A traditional

center’s frequency response changes hugely

as the listener moves away from the cabinet’s

center. This dramatic dip in the critical midrange

is clearly visible in Figure 2. NHT’s 3-way design,

detailed in Figure 3 below, eliminates this huge

dip, ensuring that every seat in your home
theater is the best seat in the house.

Fig 1. The advantage of acoustic suspension

design is clearly demonstrated in the “impulse

response” test where a speaker is sent a

momentary pulse and then observing the

resulting “ringing”.

the listener moves farther off-axis.

response over a much wider listening area.
