In this review, we will be comparing Debut 2.0 SUB3030 and SuperCube 4000, two Powered Subwoofer speakers from ELAC and 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 ELAC Debut 2.0 SUB3030 and DT SuperCube 4000 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 ELAC Debut 2.0 SUB3030and DT SuperCube 4000 have a single woofer setup however the ELAC Debut 2.0 SUB3030's woofer is 12-inch whereas the DT SuperCube 4000 features a 8-inch woofer.
Frequency Response
Debut 2.0 SUB3030 has a frequency range of 25-150 Hz whereas SuperCube 4000 has a frequency range of 16-200 Hz. With a minimum frequency of 16Hz, the SuperCube 4000 can go significantly deeper on the low side and provide stronger bass compared to the Debut 2.0 SUB3030's min frequency of 25Hz.
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
The ELAC Debut 2.0 SUB3030 has a Passive radiator type cabinet. On the other hand the DT SuperCube 4000 have Passive Radiator type enclosure. 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 ELAC Debut 2.0 SUB3030's and DT SuperCube 4000's external dimensions. ELAC Debut 2.0 SUB3030 has external dimensions of 462.0 x 451.0 x 464.0mm (18-3/16 x 17-3/4 x 18-1/4inch) whereas 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).
ELAC Debut 2.0 SUB3030 is clearly the larger of the two speakers. Its body is 170mm wider, 160mm taller and 146mm deeper than DT SuperCube 4000.
Below you can see the front view size comparison of ELAC Debut 2.0 SUB3030 and DT SuperCube 4000 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 ELAC Debut 2.0 SUB3030 is approximately 2092.6cm2 / 324.4inch2 and base area of the DT SuperCube 4000 is approximately 893.6cm2 / 138.5inch2. The Debut 2.0 SUB3030 requires 134% more surface area than the SuperCube 4000 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 ELAC Debut 2.0 SUB3030 weighs 22.80kg / 50.2lbs and the DT SuperCube 4000 weighs 11.36kg / 25lbs. This makes the Debut 2.0 SUB3030 101% heavier than the SuperCube 4000.

Two quite different sizes of subwoofer. Room volume decides this more than anything else on the page: a big driver in a small room is wasted, and a small one in a large room is worked to death.
| Area | Better | Why |
|---|
| Bass depth | B | DT SuperCube 4000 goes deeper - 16Hz against 25Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | DT SuperCube 4000 has the bigger amplifier - 1200W against 500W RMS, about 3.8dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | ELAC Debut 2.0 SUB3030 moves more air: 12" against 8" is 2.25x the cone area, not the 1.5x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | evenly matched | Both are passive radiator designs, so they roll off in much the same way. |
| Speaker-level inputs | B | 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. |
| Cabinet size | depends | DT SuperCube 4000 is about 72% smaller by volume. In a subwoofer that is a real trade rather than a preference: box volume is how you get output low down without a bigger amplifier. |
| Warranty | B | DT SuperCube 4000 carries 3 years on parts against 1 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | B | DT SuperCube 4000 costs less - $799 against $900, about 11% less. |
A ELAC Debut 2.0 SUB3030 B DT SuperCube 4000
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?
DT SuperCube 4000 is the easier recommendation: it leads on most of the measured areas and costs less. Take ELAC Debut 2.0 SUB3030 if one of the "depends" rows describes your room. 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. If placement is the constraint - a corner, behind a sofa, under a desk - DT SuperCube 4000 is the one that will actually go there, and a well-placed small subwoofer beats a badly-placed big one every time.
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.
