Our take on the NHT Classic Absolute Zero

by Kristen Schaub

Why choose bookshelf speakers?

Bookshelf speakers may be small in size, but they can deliver surprisingly big sound. Some ultra-compact models even fit on a desktop. Most are right at home in tight spaces like shelves, so they're usually good choices for your home theater's rear channels. For the best performance, try placing bookshelf speakers on solid speaker stands to help the sound really "open up." If you want full bass impact, add a powered subwoofer and enjoy punchy sound that's as deeply satisfying as that of floor-standing speakers.

Sexy little satellite speaker

NHT's Classic Absolute Zero satellite speaker is a star performer, giving you exceptional sound in a compact, stylishly curved satellite-sized enclosure. You'll hear wonderfully open midrange and crystal-clear highs that extend across a broad seating area, complemented by tight, punchy bass. The Classic Absolute Zero is a great choice for high-end stereo systems, or for home theater surround sound systems. It works best in small- to medium-sized rooms where space is limited, but your desire for high-performance sound is not. Just be sure to give this little gem plenty of good, clean amplification, and it'll reward you with surprisingly big, richly detailed sound.

Solid design keeps sound-muddying vibrations at bay

grille off shot

The Classic Absolute Zero uses a long-throw 5-1/4" polypropylene woofer set in a carefully computer-modeled acoustic suspension (sealed) enclosure. Its vibration-damping design provides plenty of strength to let the woofer rock out without adding any unwanted resonance to your movie and music soundtracks. The sophisticated 1" aluminum dome tweeter is set in a tiny bezel that allows the tweeter and woofer to be placed very close together. The result is exceptionally even on- and off-axis response, so everyone on your couch can enjoy the clear, sparkling sound.

Classic looks for a Classic system

This speaker features a beautiful, curvaceous cabinet made of very dense, rigid MDF. Its finish consists of ten layers of high-gloss paint, hand-polished between each coat for lasting beauty. Place the Classic Absolute Zero on your entertainment cabinet, or mount it to your wall using optional wall-mount brackets. It's perfectly matched to the rest of the Classic line, so you can create a high-end audio system to meet your needs. Use two to five Classic Absolute Zeros with NHT's B-10d powered subwoofer for a stunning sub/sat system. And don't forget to check out the Classic Absolute Center center channel speaker to get engaging dialogue and special effects on movie night.

Driver Technology

Broad Soundstage: The NHT Classic Absolute Zero bookshelf loudspeaker offers a tight, deep bass performance & an open, natural midrange with crystal-clear highs from a broad seating area. 

2-Way Design: The NHT Classic Absolute Zero bookshelf loudspeaker employs a 2-way speaker design with a single 1" aluminum dome tweeter and one 5.25" polypropylene woofer.

  • 1" Aluminum Dome Tweeter: The Classic Absolute Zero uses a very sophisticated 1" ferro-fluid cooled, anodized aluminum dome tweeter in a tiny bezel that features a very small, yet powerful neodymium magnet. This small bezel allows us to position the tweeter and midrange/woofer driver as close together as possible to get very even on and off axis response.
  • 5.25" Polypropylene Woofer: It uses a long-throw 5.25" polypropylene cone midrange/woofer. The woofer frame was designed entirely in-house by NHT using F.E.A. (Finite Element Analysis), and is made using a proprietary BMC (bulk moulding compound) frame, which has the high strength and low resonance of a much more expensive cast magnesium alloy frame.

Acoustical Waveguide: The Classic Absolute Zero's tweeter utilizes an acoustical waveguide to deliver, more even high frequency response, no matter what part of the room you're in.

"Wonder Bar": The Wonder Bar is a cooling/mounting bar assembly for the tweeter. It secures the tweeter from the back of the cabinet, while  cooling the tweeter, and provides another cabinet brace. The Wonder Bar is a solid aluminum bar about 5.5" x 0.75". This design allows NHT to tuck the tweeter tightly between the mid-range drivers which provides great horizontal dispersion, excellent articulation, and high power handling.

Crossover Network: The Classic Absolute Zero uses a sophisticated 3rd order crossover that was developed using computer (and human ear) aided design to carefully split the frequencies between the midrange/woofer and tweeter at just the right spot (3.0 kHz / 18 dB).

Voice Matched: The Classic Absolute Zero mates with every speaker in the NHT Classic or Absolute speaker line-up. Most typically for a satellite/subwoofer system, the Absolute Zero will be mated to the NHT Classic B-10d subwoofer (228B10D, sold separately). If you are considering building a home theater system, match the Absolute Zero with the Absolute Centeror the Classic TwoC center channel speaker (both sold separately). The Classic Absolute Zero also makes a great surround speaker for the NHT Absolute Towers (sold separately).

Enclosure Design

Acoustic Suspension: The NHT Classic Absolute Zero features an Acoustic suspension design (sealed enclosure with no ports or holes in the cabinet). The Classic Absolute Zero uses the air that is trapped in the cabinet to control and damp the woofer cone motion. The benefits of an acoustic suspension cabinet design include -

  • tight, accurate bass
  • smooth, natural midrange
  • low distortion
  • high power handling
  • smooth bass rolloff (an important benefit when blending speakers with a powered subwoofer seamlessly)

MDF Cabinet: The Classic Absolute Zero's cabinet is very robust, and uses MDF for all surfaces, and dual internal braces. The cabinet is (computer controlled) CNC-milled from 25mm MDF (for the front baffle) and 12mm MDF (for the sides and internal bracing) for rigidity and resonance control.

Curved Side-Panels: The cabinet's curved side panels help to randomize internal standing waves, which improves overall sound quality.

High-Gloss Black Finish: A hand-painted finish with 2 primer coats, 7 color coats, and 2 clear coats producing a beautiful piano quality high-gloss, black or white finish.

Detachable Grille: The speaker comes with a removable cloth grille with a rigid plastic frame.

Connections

5-Way Binding Posts: The bookshelf loudspeaker is equipped with one pair of sturdy nickel-plated 5-way binding posts to ensure a secure connection to many types of speaker cables and connectors. The binding post terminals will accept banana plugs (dual/single), pin-connectors, spade-connectors, and bare wire (up to 10AWG).

Color-Coded: The 5-way binding post terminals are color-coded so you can easily indentify positive (red) and negative (black).

Mounting Options

Applications: The Classic Absolute Zero is a great choice for stereo, distributed audio, and home theater systems.

Placement: The NHT Classic Absolute Zero can be placed on stands, on shelves, or hung on the wall. Given the high performance of this model, NHT recommends placement on either stands or on a shelf at close to ear level and equal distance from your listening position to achieve maximum fidelity.

Feet Rails: If you decide to place the speaker on a stand or shelf, the included feet rails must be attached to the bottom of the speaker (hardware included).

Wall Mounting: The optional PinPoint heavy duty side-grip wall-mounting bracket (121AM40B, sold separately) can be used to wall mount the speakers.
