Description

NHT SuperOne — Sealed Two-Ways from the Budget-High-End Era

Compact sealed two-ways from NHT’s celebrated budget-high-end era, with real bass weight and the kind of midrange that made the name.

NHT — Now Hear This

NHT — Now Hear This, out of California — built its reputation on a simple proposition: acoustic-suspension cabinets, carefully integrated drivers, and performance that embarrassed speakers costing several times more. The SuperOne was the model that carried that argument furthest. NHT’s own framing was that it took the miniature SuperZero and gave it an extra octave of bass, by way of a larger woofer in a slightly larger cabinet — with the useful side effects of greater dynamic range, better detail retrieval, and higher playback levels at lower distortion. With response reaching down to 57 Hz, a subwoofer becomes a choice rather than a requirement.

Sealed, Not Ported

The design is sealed, not ported. That matters more than it sounds. A great many compact speakers use a port to manufacture the impression of bass, and pay for it with overhang and a bass line you can hear but not follow. The SuperOne’s acoustic-suspension cabinet gives up a little output in exchange for bass that starts and stops when the recording does — which is why these have always been as satisfying on two-channel music as they are in a home theatre. The absence of a port also means they sit close to a wall, or on a wall, without the boom that would punish a ported design in the same position.

Drivers and Crossover

A 6.5-inch long-throw woofer handles the bottom and midrange, crossed to a 1-inch fluid-cooled soft dome tweeter. Both drivers are video shielded, so these sit safely beside a display of any vintage. The cabinet is a compact, heavily braced box finished in high-gloss black laminate, and it is noticeably dense for its size — the build quality is a substantial part of why the midrange stays clean. Connection is by gold-plated 5-way binding posts, which accept banana plugs, spades or bare wire.

Amplifier Matching

Sensitivity is 86 dB, which is modest, and NHT rated them for 25 to 150 watts per channel. In practice they reward a real amplifier: give them current and they open up considerably. They are not a speaker to run off the smallest receiver in the cupboard.

Radique-Fitted Enhancements

Each cabinet is fitted with Radique Audio High Density Felt pads in our signature Magenta. They protect shelving and furniture surfaces, decouple the cabinet from whatever it sits on, and stop a light speaker creeping forward under sustained bass.

Condition

Cosmetically this pair is graded Very Good, with clean cabinets and drivers throughout. High-gloss black is an unforgiving finish and these have been looked after.

The Line Is Still Alive

Worth knowing the line is still alive. NHT continues to build a SuperOne — the current 2.1, sold as a single rather than a pair. It is not the same speaker: the 2.1 uses a pulp cone woofer, a silk dome tweeter and a revised crossover. What is remarkable is the cabinet, which measures 11.6 by 7.25 by 8.5 inches — precisely the same box as the pair in front of you. Thirty years of competition, and NHT has not found a reason to change the enclosure. That says more about the original design than any specification could.

NHT was founded in Benicia, California, in 1986 by Chris Byrne and engineer Ken Kantor, and the name stands for Now Hear This. We carry NHT bookshelf speakers, towers, centre channels and subwoofers. We've had more than 40 NHT listings so far, covering more than 25 different models. Every used NHT here is inspected, tested and serviced as required, then photographed in-house and covered by our Bumper-to-Bumper Warranty and Perpetual Trade-Back Program.

The NHT models we've sold most often include the Three and SuperOne bookshelf speakers, the SW2 and Ten subwoofers and the 2.9 tower.

The NHT story

Chris Byrne, who had been Pioneer Electronics' vice-president of marketing, and engineer Ken Kantor, whose career had taken in Acoustic Research, Boston Acoustics and NAD, founded NHT in Benicia, California, in 1986. Its speakers were known for front baffles angled at 21 degrees, which NHT called Focused Image Geometry.

Jensen and Rockford. In 1990 NHT was sold to International Jensen, which also owned AR and Advent and let NHT keep its design independence. The four-way 3.3 flagship followed in the early 1990s, Kantor left in 1997 after designing the 2.9 tower, and by 2004 NHT was part of Rockford Corporation.

Today. Secrets of Home Theater calls the Classic Three of the mid-2000s NHT's best-selling model, and the C Series followed it. NHT is still based in Benicia, making acoustic-suspension and in-ceiling speakers. Chris Byrne died in December 2025.

Which NHT is which?

Original Model line (late 1980s to early 1990s): from the Model 1 to the four-way 3.3, with slim baffles angled at 21 degrees.

2.9 tower (by 1997): Ken Kantor's last NHT design, with separate terminals for bi-amplifying its woofers.

Super series: the SuperZero, SuperOne and SuperTwo, often paired with the SW2 subwoofer.

Subwoofers: the SW2 with its MA-1A amplifier, and the Classic Ten and Classic Twelve.

VT home theatre towers: such as the VT-1 and VT-3.

Classic Series (mid-2000s to 2016) and C Series: including the Classic Three.

Buying used NHT: what to check

Stabilizer bars and spikes. NHT towers such as the VT-3 and SuperTwo rely on stabilizer bars or spikes, so check they come with the pair.

Amplifier match. NHT says underpowered amplifiers are the most common cause of speaker damage, so check the tweeters on any pair that ran on a small receiver.

Subwoofer amps. If an MA-1A's front light doesn't come on, an internal fuse may have blown. On a Classic Ten or Twelve, check that the line-voltage setting is 120 V.

Baffle foam. The original angled models have anti-diffraction foam strips on the baffle, so check they are there.

Everything we list is inspected, tested and serviced as required here, and comes with our warranty.
