NHT SuperOne 6.5″ 2-Way Sealed Bookshelf Speakers — Gloss Black

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.
