Overview

Our take on the Definitive Technology SuperCube® 6000

The SuperCube 6000 sub uses a new class of high-efficiency amplifier to bring 1,500 watts to bear. Its clean muscle is preceded by a 56-bit DSP pre-amp stage that kills distortion before it ever reaches the amp, let alone your ears. The SuperCube's 9" woofer is pressure-coupled to two 10" passive radiators. This driver array gives the 6000 the capability for far greater speed, musicality, and control than the typical large single-woofer sub. The ultra-stiff woofer is encased in an incredibly rigid basket engineered to hold the massive magnet structure and large voice coil in absolute alignment. The non-resonant front and back panels are nearly 2" thick and use multiple internal bracings to make sure that you hear clean bass without sound-muddying cabinet vibrations.

Concentrated bass — be amazed by this compact cube

Definitive's Technology's SuperCube 6000 subwoofer proves that powerful bass doesn't require a big box. The tried-and-true SuperCube formula features an active woofer and two similar-sized passive radiators, all driven by a brawny 1,500-watt amplifier. This sub will fill your room with sound while taking up just over a cubic foot of space.

Flexible inputs and advanced controls

Line-level and speaker-level inputs let you connect this sub to just about any audio system. The continuously variable low-pass crossover allows you to precisely control the frequencies that your subwoofer handles. And the disappearing display lets you monitor the 6000's settings while you adjust them with the included wireless remote.

Only had it for a short time, however seems to work really good. The set up was pretty easy and the I notice a completely different "tone" to the bass effects of movies. Seems much more real and less noticeable, yet very much there.

Features

Definitive Technology SuperCube Powered Sub: The Definitive Technology SuperCube 6000 is a compact, high-quality powered subwoofer intended for use in a music or home theater system. The SuperCube 6000 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 6000 features a 1500-watt digital amplifier, 56-bit DSP, 9" woofer with dual 10" passive radiators, & an included wireless remote control. The SuperCube 6000 is finished in a piano-gloss black lacquer finish with a black non-removable cloth grille.

1500W Digital Tracking Amplifier: The Definitive Technology SuperCube 6000 features a 1500-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 14 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 consumption.

56-Bit Digital Signal Processor (DSP): The Definitive Technology SuperCube 6000 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 6000 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 6000's bass is always tight, highly detailed, & distortion free.

High 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 (14-200Hz), 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 & reliability.

Passive Radiator Design: The SuperCube 6000 features an 9" subwoofer driver pressure coupled to two 10" Ultra Low Bass Radiators. The total piston area is greater than a 14" 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 6000 is finished in piano-gloss black lacquer finish.

Ultra-Compact Design: The SuperCube 6000 measures only 12" (w) x 12.8125" (h) x 13.25" (d). Measurements include rubber-feet & cables.

Interchangeable Feet: The SuperCube 6000 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 powered subwoofer.

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 powered subwoofer.

Protection Circuit: To prevent accidental damage to the subwoofer from overdriving the system, the SuperCube 6000 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.

Controls

Subwoofer Controls: A complete array of controls allow the SuperCube 6000 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, & Night mode.

Remote Control: In addition to the SuperCube 6000'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 (CR2025).

Volume Control: The SuperCube 6000 features a rear-mounted push-button 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 main speakers.

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 frequencies.

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.

Connections

Line-Level & Speaker Level Connections: The Definitive Technology SuperCube 6000 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 6000 has a separate direct-in LFE low-level input (which bypasses the crossover network).

LFE Input: The LFE input on the SuperCube 6000 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 6000 to a receiver which features a dedicated subwoofer output which features its own low-pass crossover filter.

Low-Level Inputs: If your receiver does not feature a dedicated subwoofer output, but does feature stereo RCA outputs, you can use the SuperCube 6000'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 6000 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 system turn-on.
  • 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 control.

Detachable AC Power Cord: The SuperCube 6000 includes a detachable 7' AC power cord. The SuperCube 6000 must be plugged into a 120V, 60Hz electrical socket (use an unswitched outlet if possible).

Why did you buy this?

Magazine review. [ Garnot  May 08, 2017 ]
I have had several Def Tech products and loved them all. Plus, Crutchfield had it at a great price and I know they will take care of me should any problems arise. [ Michael  Mar 17, 2017 ]
My 5.1 in-ceiling system had an in-wall sub that could not deliver the goods. Needed a compact sub that looked great while delivering the punch my large, open family room needed. The remote control added a whole new way to dial in the sound scape I wanted. [ G  Jan 16, 2017 ]
Good reviews [ Mark  Nov 19, 2016 ]
This was one of my concern when i request advisory, and was recommended by Marshall, the adviser. [ Juan  Nov 18, 2016 ]

[ Kenny  Jun 03, 2017 ]  Staff
I'm extremely pleased with this unit. I'm using a Sony STR-DN1040 AV receiver driving 2 Klipsch Forte IV towers, a Klipsch KG-2.2V center speaker and Boston Acoustic book shelf speakers. All of the speakers are roughly 25 years old and still kicking. I listen to mostly music while the wife and daughter use it more for movies. I use about 40% of the available volume on the SuperCube when I'm rocking out. Maybe 30% for general listening. I have the unit in the front corner of my room. The first time I had the volume at 50% I had dishes in the cupboards moving around. The kitchen and my family room are connected in an open room design wit 12 foot ceilings. I couldn't be happier with my choice of the SuperCube 6000. For a small foot print it sure delivers. Hope this is helpful... [ MICHAEL J  Jan 07, 2015 ]
The Super Cube 6000 I feel will give you everything that you are looking for and a whole lot more. When I listen to music I tend to keep it turned down around the lower 20's and when watching a movie or football game it gets turned up around 30. It is VERY powerfull, versatile and adjustable! "at 30 it is rocking a 25x25 great room just like being at the movies". Do not know if my earlier coment is in there but I had a $3K Velodyne Sub and there is no comparison! I mentioned adjustable earlier which is why I really enjoy the REMOTE, would not get one without it and to me better to have more POWER and not need it than to have less and wish I did. I am VERY satisfied with it and my choice of music is also jazz and contemporary rock. [ NICHOLAS A  Jan 03, 2015 ]
I was very unsatisfied with bass this sub delivered. I want to hear good thunder in a movie and by itself this mini cube was not up to the task. I ended up purchasing a dual sub receiver and am useing 2 mini cubes and that solved the problem. If your Sony is pushing good base already keep it and save your money unless you wish to update your system like I did with mine. [ GARY  Jan 03, 2015 ]
If you are looking for a clean,sharp bass, not too heavy at low mid volumes you should be very pleased at this price ,jump on it,you should have no regrets [ JAY  Jan 02, 2015 ]
Yes I love this sub! It has amazing deep bass. I use it for my home theater setup. [ Douglas  Jan 02, 2015 ]
You will not be disappointed with this sub woofer it is an excellent choice. It sounds good at all levels and is priced right for the quality you receive. [ DAVID  Jan 02, 2015 ]
This sub is really amazing. It provides plenty of tight low base from a tiny package. I replaced an old DT Powerfield 18 with this and was a little hesitant about going from an 18" driver to a 9" driver, but I also really wanted something that didn't take up an entire corner of the living room. It was well worth the money and I have been totally satisfied. [ MATTHEW L  Jan 02, 2015 ]
