In this review, we will be comparing SuperCube 4000 and SuperCube 2000, two Powered Subwoofer speakers by Definitive Technology. Being Powered subwoofers, they both have built-in amplifiers so you don't need an external power amp or an integrated amp to power them. Let's have a brief look at the main features of DT SuperCube 4000 and DT SuperCube 2000 first before getting into our more detailed comparison.
The sections below take each area in turn: driver and amplifier, frequency response, physical size and connectivity.
Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Both DT SuperCube 4000and DT SuperCube 2000 have a single woofer setup however the DT SuperCube 4000's woofer is 8-inch whereas the DT SuperCube 2000 features a 7.5-inch woofer.
Frequency Response
SuperCube 4000 has a frequency range of 16-200 Hz whereas SuperCube 2000 has a frequency range of 20-200 Hz. With a minimum frequency of 16Hz, the SuperCube 4000 can go slightly deeper then the SuperCube 2000's min frequency of 20Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Subwoofer class in our database.

Cabinet Type
Both DT SuperCube 4000 and DT SuperCube 2000 have Passive Radiator type cabinets. Passive Radiator type subwoofers sports a non-powered cone that moves in response to the main woofer to move air out in order to generate stronger bass in a smaller body compared to ported or sealed designs.
Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare DT SuperCube 4000's and DT SuperCube 2000's external dimensions. DT SuperCube 4000 has external dimensions of 302.0 x 281.0 x 318.0mm (11-7/8 x 11-1/16 x 12-1/2inch) whereas DT SuperCube 2000 has external dimensions of 275.0 x 261.0 x 321.0mm (10-13/16 x 10-1/4 x 12-5/8inch).
DT SuperCube 2000 is 20mm narrower and 27mm shorter than DT SuperCube 4000 but it is also 3mm deeper.
Below you can see the front view size comparison of DT SuperCube 4000 and DT SuperCube 2000 in scale.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the DT SuperCube 4000 is approximately 893.6cm2 / 138.5inch2 and base area of the DT SuperCube 2000 is approximately 837.8cm2 / 129.9inch2. The SuperCube 4000 requires 7% more surface area than the SuperCube 2000 which gives it a small disadvantage on placement in tight spaces.
Weight Comparison The weight of a subwoofer may become an important factor if you need to move and reposition the unit often to find the optimal positioning, also known as 'Subwoofer Crawling'. The DT SuperCube 4000 weighs 11.36kg / 25lbs and the DT SuperCube 2000 weighs 11.36kg / 25lbs.
Here is a comparison of how SuperCube 4000 and SuperCube 2000's weights compare with the average, max and min weights in Powered Subwoofer class.

Size, drawn to scale
Both subwoofers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same floor and pushed back to the same wall, so the bigger one visibly takes more of the room.
Near-identical footprints. DT SuperCube 4000 is 27mm taller.

Siblings in Definitive Technology's SuperCube range - same design thinking, different size. It comes down to your room and your budget.
| Area | Better | Why |
|---|
| Bass depth | A | DT SuperCube 4000 goes deeper - 16Hz against 20Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | A | DT SuperCube 4000 has the bigger amplifier - 1200W against 650W RMS, about 2.7dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | evenly matched | Near-identical radiating area (8" against 7.5"). |
| Enclosure | evenly matched | Both are passive radiator designs, so they roll off in much the same way. |
| Speaker-level inputs | A | DT SuperCube 4000 takes a speaker-level connection as well as line level. That is what lets it work with an integrated amplifier or a vintage receiver that has no subwoofer output at all. |
| Phase control | A | DT SuperCube 4000 has a phase control. Without one, the only way to fix a cancellation at the crossover is to move the box. |
| Price | B | DT SuperCube 2000 costs less - $599 against $799, about 25% less. |
A DT SuperCube 4000 B DT SuperCube 2000
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both subwoofers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: DT SuperCube 4000 measures better, DT SuperCube 2000 costs about 25% less. In a normal room, placement will make a bigger difference than the gap between these two. Check your amplifier first: if it has no subwoofer or preamp output, DT SuperCube 4000 is the only one of these two you can connect at all.
One thing outweighs everything above: where the subwoofer stands. Room modes can add or remove 10dB or more at a given seat, which is far larger than any difference on this page. Before spending more, try the sub in two or three positions - the crawl test, where you put it in the listening seat and crawl the room to find where the bass sounds best, costs nothing and usually beats an upgrade.
