In this review, we will be comparing Muro SUB2020 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 Muro SUB2020 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 Muro SUB2020and DT SuperCube 4000 have a single woofer setup however the ELAC Muro SUB2020's woofer is 10-inch whereas the DT SuperCube 4000 features a 8-inch woofer.
Frequency Response
Muro SUB2020 has a frequency range of 28-200 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 Muro SUB2020's min frequency of 28Hz.
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 Muro SUB2020 has a Acoustic Suspension type cabinet. Acoustic Suspension aka Sealed type subwoofers have enclosures that are sealed hence no ports or holes exists on the cabinet. Sealed designs helps to provide more accurate and tight bass responses compared to ported designs. 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 Muro SUB2020's and DT SuperCube 4000's external dimensions. ELAC Muro SUB2020 has external dimensions of 399.0 x 185.0 x 515.0mm (15-11/16 x 7-1/4 x 20-1/4inch) 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).
DT SuperCube 4000 is 97mm shorter and 197mm less deeper than ELAC Muro SUB2020 but it is also 96mm wider.

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 Muro SUB2020 is approximately 952.8cm2 / 147.7inch2 and base area of the DT SuperCube 4000 is approximately 893.6cm2 / 138.5inch2. The Muro SUB2020 requires 7% 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 Muro SUB2020 weighs 12.73kg / 28lbs and the DT SuperCube 4000 weighs 11.36kg / 25lbs. This makes the Muro SUB2020 12% heavier than the SuperCube 4000.

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. ELAC Muro SUB2020 stands 197mm further into the room. ELAC Muro SUB2020 is 97mm taller.

A sealed subwoofer against a passive radiator one. That is the most consequential line on this page: it decides how the bass rolls off, how it behaves in a small room, and how much output you get for the size of the box.
| Area | Better | Why |
|---|
| Bass depth | B | DT SuperCube 4000 goes deeper - 16Hz against 28Hz. 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 200W RMS, about 7.8dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | ELAC Muro SUB2020 moves more air: 10" against 8" is 1.56x the cone area, not the 1.25x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | depends | ELAC Muro SUB2020 is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; DT SuperCube 4000 is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| 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. |
| Wireless option | depends | Only ELAC Muro SUB2020 offers a wireless link (as a paid option). It decides where the sub can go if you cannot run a cable, and is worth nothing if you can. |
| Driver placement | depends | ELAC Muro SUB2020 fires side or down and DT SuperCube 4000 fires front. A down-firing driver is more forgiving of a grille-less look and of a hard floor; a front-firing one is the safer choice on a thick carpet or a suspended timber floor. |
| Cabinet size | depends | DT SuperCube 4000 is about 29% 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 $1,000, about 20% less. |
A ELAC Muro SUB2020 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 Muro SUB2020 if one of the "depends" rows describes your room. Films or music? If this is mainly a home cinema, DT SuperCube 4000 will hit harder for the money; if it is mainly for music in a normal-sized room, ELAC Muro SUB2020 is usually the easier one to make sound right. 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.
