Huge bass, tiny box

If you want high-impact bass excitement without sacrificing a large amount of floor space, then this is the subwoofer for you. Built on the success of Definitive's SuperCube series, the new SuperCube 2000 provides huge bass performance in a compact, room-friendly enclosure that measures less than a cubic foot. The secret to its success is an active woofer/passive radiator combination that produces big sound despite the cabinet's small size. And it's powered by a built-in 650-watt amplifier that really shows off this little sub's tight, accurate bass response.

A unique approach to rock-solid bass

Back panel close-up

The SuperCube 2000 contains a 7-1/2" woofer pressure-coupled to two 7-1/2" passive radiators. This driver array gives the SuperCube 2000 the advantage of far greater speed and control than any large single-woofer sub could achieve. It's sure to please both movie and music lovers with its ability to produce explosive effects for Hollywood blockbusters, as well as precise, musical bass for all kinds of music.

The specially engineered, non-resonant cabinet uses multiple internal bracings to make sure that you hear clean bass without sound-muddying vibrations. And its single LFE input makes setup with multichannel home theater receivers quick and easy.

Product Highlights:

  • built-in 650-watt amplifier
  • frequency response 20-200 Hz
  • 7-1/2" long-throw woofer pressure-coupled to two 7-1/2" low bass radiators
  • bass-reflex (passive radiator) enclosure
  • auto on/off
  • LFE input for use with home theater receiver's subwoofer output
  • piano-gloss black finish
  • 10-1/4"W x 10-13/16"H x 12-5/8"D
  • warranty: 5 years woofer, 3 years amplifier
  • Our 60-day money-back guarantee

Why add a powered subwoofer?

A powered subwoofer gives you bass you can feel as well as hear. Our customers love the depth and impact their subs add to music and movies. We hear comments like "it brings out sounds I didn't know existed in discs I've watched a million times." Powered subwoofers aren't just for big bass that rattles your picture frames; they can also deliver tight, accurate lows. If you haven't shopped for a powered sub in a while, you might be surprised at how small they get. Look for an ultra-compact model if you want to tuck your sub away under an end table or in a corner.

Features

Definitive Technology SuperCube Powered Sub: The Definitive Technology SuperCube 2000 is a compact, high-quality powered subwoofer intended for use in a music or home theater system. The SuperCube 2000 powered subwoofer allows for easy, seamless integration into almost any two-channel or multichannel speaker system; delivering true, accurate, and extremely deep bass in any room. The SuperCube 2000 is finished in a piano-gloss black lacquer finish with a black non-removable cloth grille.

650 Watt Class D Amplifier: The SuperCube 2000 is powered by a 650-watt (RMS) class D amplifier. The result is high-definition bass performance extending effortlessly down to 20 Hz.

Passive Radiator Design: The SuperCube 2000 features a 7.5" high-definition long-throw woofer pressure coupled to two side-firing 7.5" Ultra Low Bass Radiators. The total piston area is greater than a 12-inch diameter woofer but with far greater speed, musicality, and control than a single large diameter woofer could deliver.

Non-Resonant Cabinet: The cabinet of a loudspeaker plays a large part in its sonic performance. Resonance and vibration can add unwanted distortion as well as drain away important energy from the system. The Definitive Technology SuperCube 3000 powered subwoofer utilizes a wood-composite cabinet with internal bracing, that has been specifically engineered to be totally inert and vibration free, to ensure you of pure sonic reproduction.

Ultra-Compact Design: The SuperCube 2000 measures only 10.25" (w) x 10.8125" (h) x 12.625" (d), and weighs only 25 lbs. Measurements include rubber-feet and cables.

Interchangeable Feet: The SuperCube 2000 comes with 4 rubber-feet and 4 spiked-feet for safe and secure placement of the powered subwoofer on your carpet or hardwood floors. The spiked feet add 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 2000 features an internal overload protection circuit, which will turn the subwoofer off or down when overdriven or overheated and will then resume normal operation after a few minutes.

Controls

Subwoofer Level: The Definitive Technology SuperCube 2000 features a rear-mounted volume control. This control is used to raise or lower the output level of the subwoofer in relation to the other speaker in your system.

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.

Note: You may hear a pop from the speaker when the amp powers up or powers down; this is normal.

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

LFE Subwoofer Input: The Definitive Technology SuperCube 2000 is equipped with a LFE mono-Subwoofer RCA input. Simply connect the powered subwoofer to your A/V receiver's LFE mono-Subwoofer RCA output via a mono-Subwoofer cable. Because the SuperCube 2000 is only equipped with an LFE input, it does not feature a built-in crossover control. You will use the subwoofer output crossover in your A/V receiver to set the low-pass crossover frequency for the SuperCube 2000.

Note: The SuperCube 2000 does not feature stereo RCA inputs/outputs or speaker-level inputs/outputs.

Detachable AC Power Cord: The SuperCube 2000 includes a detachable 7' AC power cord. The SuperCube 2000 must be plugged into a 120V, 60Hz electrical socket (use an unswitched outlet if possible).

Definitive Technology SuperCube 2000

Written By Bret, Broken Arrow, Oklahoma on Wednesday, December 03, 2014

Crutchfield Customer Review (What's this?)

Good looking clean modern design. Average performance. Paired with Mythos sound bar for Pioneer Elite display in bedroom. Adds the low end missing with the sound bar. Too costly.

Pros: Size & appearance

Cons: High Cost & Marginal Output

nice base in a small place

Written By hidden base, Florida on Monday, December 01, 2014

Crutchfield Customer Review (What's this?)

I needed a low end to our system but needed to please my wife by not having it visible or break the bank. This unit adds a nice low tone and when we turn it up for dance parties it hangs in there beat for beat...

Pros: Big sound in a small cube

Cons: can't adjust band width

Deep rich base

Written By clarehills, San Diego CA on Tuesday, October 07, 2014

Crutchfield Customer Review (What's this?)

Fantastic, rich, deep base. If you like sci-fi movies or playing shooting games (battle field in my case) you are going to really enjoy the feel & sound from this subwoofer

Pros: Deep, rich sound that you can feel as much as hear it

Cons: none so far

SuperCube 2000

Written By Dave, San Jose on Tuesday, March 04, 2014

Crutchfield Customer Review (What's this?)

I was a bit skeptical about the Sub, as it is kind of small. After I properly hooked up the unit, it produces a decent quality base sound. Amazing.

Amzaing depth

Written By Supercube 2000, NJ on Friday, October 11, 2013

I have 2 subs in my current 11.2 arrangement. All of my speakers except for the 2 height front are in-wall definitive tech. I have been impressed with the performance from the DT company and was reading about the super cube. I wanted to add a 3rd sub to fill the range gap. I currently have a 15" running on a 1600rms ashley amp and, a cerwin vega 12" self amp. Wasn't sure if the supercube was going to add to the experience. It does! I plugged it in and at 50% volume the cube could have stood alone with out the other 2 subs. It won't shake the couch like the 15" but it is a very clear and noticeable bass. Fills mid, mid lows, and audible range extremely well. Definitively out performs my 12" and the size is a big bonus. Terrible movie but to configure a bass filled system try out "Pacific Rim." I would recommend the cube even if you are thinking about a solo sub.

Pros: Small Size, efficient input and knob (no extras cause you don't need them, and keeps it simple if you don't know what you are doing), has 2 sets of feet for the speaker carpet cleats and adjustable flats, 650 watt,

Cons: Price, top cover could be mounted tighter, doesn't seem to benefit from corner placement

A Little Powerhouse

Written By EddieC, Brooklyn, NY on Sunday, September 08, 2013

Crutchfield Customer Review (What's this?)

Originally, I was enquiring about the Definitive Technology Pro Sub 1000 but Shane, the Crutchfield sales rep., convinced me to try the Super Cube 2000. I was a bit skeptical at first but decided to try it. I have waited two months in order to observe its performance before giving this review. Now, I am considering whether to purchase another since it has exceeded my expectations. I read an adverse review, here, and wonder what the reviewer was really talking about.

Pros: Great performer!

Cons: None

Crutchfield Customer Review (What's this?)

Good bass and the compact size of it is very nice. It can be set just about everywhere and not look bulky. I'm sure there's much better out there but this unit works great for my needs.

Pros: Compact size Good bass Easy install

Sounds like IMAX

Written By Ht guy, boston, MA on Thursday, November 22, 2012

calibrated using Startrek motion picture. Wow, what a sound! Sounds like sitting in an IMAX theatre.

Pros: Everything..

Cons: none.

Not Enough....

Written By Anonymous, san jose, ca on Friday, November 09, 2012

Crutchfield Customer Review (What's this?)

so i decided to experiment with this new technology for bass, thought maybe bigger isnt always better these days. I was disappointed..... i got more bass from my front speakers than from the super small "bass" box... I love definitive technologies speakers, but this little box just doesnt put out enough for my needs... There's always the chance i recieved a bad unit, and an even slimmer chance i installed incorrectly, but i felt the woofer cut-out at higher volumes when testing the sub with some bass music, several times... i moved on to a 12" polk sub box at the same price, and my conclusion is: BIGGER IS BETTER....

Pros: small, VERY nice looking.

Cons: DOESNT PERFORM. at least not for my needs... i like to FEEL the music and the movie action scenes, not just hear it
