Overview: The NHT Super 8 powered subwoofer is great for use with any
high-quality compact speaker that's bass shy, and is a perfect match for the NHT
SuperZero satellite speakers (228SZ20B, sold separately). The NHT Super 8 powered subwoofer delivers high-end deep bass performance and is great
for both home theater & stereo music. Adding a powered subwoofer to your home
theater or home stereo system offers plenty of benefits -
- takes the deep bass load off of your main speakers, so they play louder
with lower distortion
- helps your amplifier by handling the deep bass (your amp
handles just the midrange and high frequencies)
- blends seamlessly with your main speakers and disappears
DSP (Digital Signal Processing )Engine: The integrated DSP engine dynamically controls the powered subwoofer's
amplifier power, equalization, and filter functions. As a result, the Super 8
plays louder, deeper, with more control. The DSP's built-in limiter and
compressor even protects the woofer from being over-driven.
110 Watt Amp: The NHT Super 8 powered subwoofer employs a built-in
BASH amplifier rated at 110 watts, 4-ohms, 0.5% THD.
Note: Always provide adequate space for ventilation of the
subwoofer amplifier. Do not place the powered subwoofer directly against a
wall, curtains, or any other surface.
8" Woofer: The NHT Super 8 powered subwoofer houses a heavy-duty,
long-throw, pulp-cone 8" woofer that has been custom designed by NHT
specifically for the Super 8's closed box, acoustic suspension design. The
loaded woofer fires forward into the room (not down-firing).
Sealed Enclosure: The NHT Super
8 powered subwoofer features a sealed enclosure. It has no holes or ports that
can interact with its surroundings making it ok to put it wherever it fits in
your space, instead of the other way around. An instead of boomy, sloppy bass -
you get deep, accurate, natural sounding bass.
Gloss Black Finish: The Super 8 powered subwoofer comes beautifully
wrapped in the signature NHT gloss black finish.
Mounting Feet: The NHT Super 8 comes with four aluminum spiked feet
for carpeted flooring. There are also four aluminum floor protectors included,
in case you have hardwood or tile flooring. The feet are adjustable to combat
against uneven floors.
Subwoofer Volume Control: The NHT Super 8's volume control
(min/max) matches the
powered subwoofer's volume to the your satellite speaker's output.
EQ Switch: A Unique EQ switch tunes the powered subwoofer for your
choice of Movie or Music. The Movie setting augments soundtracks and special
effects, while offering higher output. The Music setting will provide lower,
more balanced bass response.
Crossover: The NHT Super 8 incorporates a variable low-pass crossover
(60-150Hz). The crossover is active for the powered subwoofer's stereo
line-level and speaker level inputs. It does not function with the LFE input
(you will need to use the low-pass crossover built into your A/V receiver).
Phase Control: A phase control (0/180-degrees) integrates the Super
8's output with your satellite speakers for a more blended, smoother sound.
Auto On/Off: The NHT Super 8 will automatically turn-on when it senses
an audio signal through its line-level or speaker-level terminals. The powered
subwoofer will then turn itself off when there is no sound present for
approximately 20 minutes. Or, you can leave the powered subwoofer always on.
USB Wireless Adapter (optional): There is a USB (type-A) connection
for use with a future NHT wireless audio adaptor (sold separately).
LFE/Stereo Input: The Super 8 has an LFE/RCA input for connection to
your receiver's sub out, and stereo RCA inputs for your receiver's line-level
- LFE/Subwoofer Input: The most common connection for A/V receivers
today is to run a single audio cable from the receiver's Subwoofer or LFE
output to the powered subwoofer's LFE/RCA input. The LFE input bypasses the
powered subwoofer's crossover control and uses the built-in crossover
settings in your receiver.
- Stereo RCA Input: Some older A/V or stereo receiver only offer
preamp outputs. In this case, connect a pair of audio cables from the
left/right preamp outputs on the receiver to the two stereo RCA inputs on
back of the powered subwoofer. With this connection, you will use the
powered subwoofer's integrated crossover controls.
Speaker-Level Inputs/Outputs: There are speaker-level inputs with a
high-pass (bass removed) speaker level outputs to connect your satellite
speakers, if your receiver lacks LFE/Stereo RCA Inputs. Simply connect a pair of
stereo speaker wires from the receiver to the speaker-level input terminals on
the powered subwoofer. Then connect a second stereo pair of speakers wires from
the powered subwoofer to each satellite speaker. With this configuration, you
will use the powered subwoofer's integrated crossover controls. Not only will
the crossover prevent high-frequencies from reaching the powered subwoofer, it
will prevent low-frequencies from reaching your connected satellite speaker to
prevent unwanted distortion.
Universal Power Supply: The Super 8 uses a super-efficient, universal
power supply (100v to 240v) to deliver full output anywhere in the world.
