Our take on the NHT SuperPower

by Ralph Graves

Build a sweet-sounding desktop audio system

Want to make your smartphone, tablet, or laptop the center of a great stereo system? You don't need super powers to do it. Just start with two NHT SuperPower speakers. Each high-performance speaker has its own amplifier built in, so there's no need for a receiver. Add an NHT PVC PC passive volume control (sold separately), and you have a compact desktop audio system that delivers rich, accurate NHT sound.

NHT SuperPower

Combine two SuperPower speakers with a NHT PVC PC volume control for a simple, great-sounding system

Plenty of audio "muscle" underneath that handsome exterior

The SuperPower houses a 1" silk dome tweeter and 4-1/2" woofer inside its strong, well-braced cabinet. Like all of our favorite NHT speakers over the years, this one uses a sealed, "acoustic suspension" enclosure for tight, musical bass and articulate midrange. And with 90 watts of clean, cool-running amplification, the SuperPower has no problem delivering accurate sound you'll enjoy even when you're across the room.

Optional stands reduce desktop vibrations and position your speakers for better listening.

You can use the provided rubber pads to reduce vibrations on your desktop. Or pick up a pair of optional NHT DeskStands to raise your speakers and position them at the optimal listening angle. Looking for serious low end? Add NHT's perfectly matched Super 8 powered subwoofer for deep, hard-hitting bass that will make your music sound bigger and fuller.

Overview: The NHT SuperPower is a powerful self-amplified, mini-speaker. The compact powered speaker features a 2-way speaker design and has it's own internal, 90-watt amplifier. The NHT SuperPower can be connected directly to computers, smartphones, tablets, Apple devices (iPod/iPhone/iPad), video game consoles, and TV's; or practically any audio source which features an headphone or audio output. 

90-Watt Class D Amplifier: The NHT SuperPower employs a built-in 90-watt Class D amplifier. This 90-watt  digital amplifier is extremely energy efficient, converting over 90% of the incoming electricity to pure, low-distortion output power.

Two-Way Speaker Design: The SuperPower uses a two-way speaker design with  a 4.5" treated-paper cone woofer and 1" silk dome, ferro-fluid cooled tweeter mounted in a compact sealed enclosure for lifelike vocals and excellent imaging.

Acoustic Suspension Enclosure: The sealed, or "acoustic suspension" designed enclosure is very important to the SuperPower's performance. In an acoustic suspension design, the air trapped inside the enclosure acts as a spring to control the woofer cone's motion which helps keep distortion low and allows the small SuperPower to produce the sort of deep bass and dynamics usually associated with much larger speakers. The speaker enclosure is internally braced for added rigidity.

Optional Desktop Stand: NHT's optional Desktop Stand (228DSKSTND, sold separately) will open up the midrange vocals and make the soundfield larger and more realistic.


Power Switch: The NHT SuperPower features only one control. There is a power switch located on the back of the speaker which turns the powered speaker On/Off.

Add-On Passive Volume Control: The NHT passive volume control (228PVCPC, sold separately) will make things sound better and puts a knob handy for volume control.


Analog RCA Output: The NHT SuperPower speaker is fitted with a single RCA line-level input to connect your external audio source that features a headphone or audio output. A 39" stereo minijack to stereo RCA cable is provided.

Detachable AC Power Cord: The NHT SuperPower operates off of standard household AC current (100-120V; 60Hz/1.2A) using the supplied 6' detachable AC power cord.

Super 8 Subwoofer (sold separately): The NHT Super 8 subwoofer (228SUPER8, sold separately) can be added to the SuperPower speaker system to fill a bigger space or to add bigger bass and dynamics. The SuperPower does not feature a subwoofer output; your add-on subwoofer will need to connect to either the NHT passive volume control (sold separately) or your audio source.
