Definitive Technology SuperCube Powered Sub: The Definitive Technology SuperCube 4000 is a
compact, high-quality powered subwoofer intended for use in a music or home
theater system. The SuperCube 4000 powered subwoofer allows for easy, seamless
integration into almost any two-channel or multichannel speaker system;
delivering true, accurate, & extremely deep bass in any room. The Definitive Technology SuperCube
4000 features a 1200-watt digital amplifier, 56-bit DSP, 8" woofer with dual
8" passive radiators, & an included wireless remote control. The SuperCube 4000 is finished in a piano-gloss black lacquer finish with a black
non-removable cloth grille.
Digital Tracking Amplifier: The Definitive Technology SuperCube 4000
features a 1200-watt (RMS) digital tracking amplifier that is optimized for real
world power demands to deliver low distortion & high output. As well as
producing high continuous power to cleanly reproduce sustained bass (down to 16
Hz), this all-new Definitive Technology digital amp has a high crest factor to
deliver considerably higher power during short, transient peaks such as bass
drum kicks & on-screen artillery blasts. You'll enjoy high volume, high impact,
& low distortion bass from your favorite action/adventure films & TV shows
without sacrificing the smooth response & quick precision needed for music.
Note: As well
as being powerful, the new Definitive Technology digital amp is
environment-friendly. The amplifier goes into idle mode after less than 30
minutes of no audio signal. When in idle mode the amp draws a mere 1/2 Watt
or less of current, meeting international standards for low energy
56-Bit Digital Signal Processor (DSP):
Definitive Technology SuperCube 4000 has an integrated 56-bit Digital Signal
Processor (DSP) that extends & improves the bass response. Multiband digital
protection systems tightly monitor & control the woofer system to prevent
distortion & woofer damage at ultra-high volume levels with a minimum of audible
artifacts. In contrast to simpler one-band compression/limiting circuits used in
competing subwoofer amp designs, the Definitive Technology SuperCube 4000
features a Multiband Dynamic Range Optimizer (M-DRO) that divides the frequency
range into multiple bands. If the DSP detects an overdrive condition in the
upper bass range, it applies just the right amount of compression & to prevent
distortion to just that range without compressing the low bass, thereby vastly
reducing the audible compression artifacts. As a result, the SuperCube 4000's
bass is always tight, highly detailed, & distortion free.
Definition Drivers: The powerful, high-definition drivers used in the new
SuperCubes were specifically engineered for their task: to deliver rock-solid
low distortion bass, reaching down to the lowest frequencies (16-200Hz), with an
outstanding quality of superior transient response ("tightness"). The special
ultra-stiff cones are joined to specially formulated surrounds & long-throw
voice coils & spiders. The incredibly rigid cast aluminum baskets are engineered
to hold the massive magnet structures & large voice coils in absolute alignment.
The high temperature voice coils are made of aluminum wound with triple
insulated ultra-pure copper wire & baked in epoxy for superior power handling &
Passive Radiator Design: The SuperCube 4000 features an 8" subwoofer
driver pressure coupled to two 8" Ultra Low Bass Radiators. The total piston
area is greater than a 12-inch diameter woofer but with far greater speed,
musicality, & control than a single large diameter woofer could ever deliver.
Non-Resonant Cabinet: The
cabinet of a loudspeaker plays a large part in its sonic performance. Resonance
& vibration can add unwanted distortion as well as drain away important
acoustical energy from the system. Definitive's subwoofer enclosures have been
specifically engineered to be totally inert & vibration free, to ensure you of
absolutely pure sonic reproduction. The front and rear panels are nearly 2"
thick & the cabinet incorporates multiple internal braces to ensure total
solidity. The SuperCube 4000 is finished in piano-gloss black lacquer finish.
Ultra-Compact Design: The SuperCube 4000 measures only
11.0625" (w) x
11.875" (h) x 12.5" (d). Measurements
include rubber-feet & cables.
Interchangeable Feet: The SuperCube 4000 comes with 4 rubber-feet
& 4 spiked-feet for safe & secure placement of the powered subwoofer on
your carpet or hardwood floors. The spiked feet add approximately 0.125" of height to the
Placement: There are some general guidelines that you should use when
locating the powered subwoofer.
- For best results, place the subwoofer on the same side of the room as
your front speakers.
- For maximum output, the subwoofer should be placed in a corner or
against the wall, leaving approximately 2" to 4" clearance between the
powered subwoofer and the wall(s).
- Corner placement will increase the powered subwoofer's output.
- An acoustic effect called "standing waves" or "room modes" may cause
uneven bass at various locations throughout the room. This phenomenon is a
function of the dimensions of the room and not due to the design of the
Protection Circuit: To prevent accidental damage to the subwoofer from
overdriving the system, the SuperCube 4000 features an internal overload
protection circuit, which will turn the subwoofer off or down when overdriven or
overheated & will then resume normal operation after a few minutes.
Subwoofer Controls: A complete array of controls allow the
SuperCube 4000 to be perfectly integrated with any stereo or multi-channel audio
system, and tuned for optimum performance in any room.
Front-Panel LCD: A front-panel LCD alphanumeric character display
(red) indicates control settings automatically & turns off when not in use. The
front-panel LCD indicates Volume level, Crossover frequency, Phase, EQ mode, &
Remote Control: In addition to the SuperCube 4000's rear-panel
controls, the powered subwoofer comes with an IR remote control for wireless
operation. The remote includes Power, Volume, Crossover, Phase, EQ, Night Mode,
Mute, & Display controls.
Note: The remote operates off of a single 3V lithium battery
Volume Control: The SuperCube 4000 features a rear-mounted
volume control (0-40). This control is used to raise or lower the output level of the
subwoofer in relation to the other speaker in your system.
Note: There is also a mute button on the remote control to zero
the volume level quickly.
Variable Low-Pass Crossover: The Definitive Technology
powered subwoofer features a continuous variable low-pass filter control on the
back-panel. This filter is continuously variable between 40 and 150 Hz. It
"rolls-off" (24dB/oct) the high-frequency response of your subwoofer so only
low-frequencies below the desired setting will be heard. This low-pass filter
control is used to obtain the optimum transition between the subwoofer and your
Variable Phase Alignment: The powered subwoofer features a
rear-panel push-button phase control (0/90/180/270-degrees). This
control is used to perfectly blend the output of your subwoofer with your main
speakers to compensate for any possible problems due to placement constraints.
EQ: You can toggle between 4 specific preset equalization settings to
suit your music/movie soundtrack or preference.
- EQ1: Maximizes deepest octave bass response at the sacrifice of
maximum volume level (good choice for pipe organ & symphonic recordings).
This setting should not be used a high volume levels.
- EQ2: Raises relative level of mid-bass frequencies (good choice
for hip-hop & rock music, or movie soundtracks with weak bass).
- EQ3: Raises the level of mid- & ultra-low bass frequencies (a
great setting for movies when not played at ultra-high volume levels).
- EQ4: The best setting to use when achieving maximum volume levels
with minimal distortion is more important than reproducing the lowest
Night Mode: Night Mode applies dynamic range compression to the woofer
so that the loudest bass in a movie doesn't get loud enough to wake the parents,
kids, or spouse at night.
Auto Turn-On Circuit: The powered subwoofer has a special
power circuit which automatically turns the powered subwoofer on when a signal
is fed to the loudspeaker and turns it off when there is no signal present, so
it does not require an on-off switch.
LED Indicator: The red LED on the back panel of the powered
subwoofer will light up when a signal is sensed and the amplifier turns on. It
will automatically turn off with the powered subwoofer, a little while after the
signal is discontinued.
Line-Level & Speaker Level Connections: The Definitive
Technology SuperCube 4000 powered subwoofer has a complete range of inputs &
outputs to allow easy and effective hookup to any system. Both (high) speaker
level & low-level inputs are provided in case you do not have a subwoofer
output. In addition, the SuperCube 4000 has a separate direct-in LFE low-level
input (which bypasses the crossover network).
LFE Input: The LFE input on the SuperCube 4000 is a mono-RCA
input which is not affected by the subwoofer's low-pass filter or low-pass
crossover control. It is designed to connect the SuperCube 4000 to a receiver
which features a dedicated subwoofer output which features its own low-pass
Low-Level Inputs: If your receiver does not feature a
dedicated subwoofer output, but does feature stereo RCA outputs, you can use the
SuperCube 4000's stereo RCA low-level inputs (which provide its own dedicated
variable low-pass crossover circuit) to connect the subwoofer to your receiver,
Speaker Level In: The Speaker Level inputs (5-way binding posts)
are designed to be used on receivers or amplifiers that do not incorporate any
RCA type subwoofer outputs. If your receiver is equipped with an RCA type
subwoofer outputs, these speaker level inputs should not be utilized.
Remote Connections: The Definitive
Technology SuperCube 4000 features 12V trigger & IR remote inputs.
- 12V Trigger Input: 3.5mm jack
which connects to the 12V trigger output of an AV receiver for one-button
- IR Input: 3.5mm jack used to
connect an optional IR remote repeater (sold separately), when the powered
subwoofer is hidden & cannot be operated from the included IR remote
Detachable AC Power Cord: The SuperCube 4000 includes a detachable 7'
AC power cord. The SuperCube 4000 must be plugged into a 120V, 60Hz electrical
socket (use an unswitched outlet if possible).
