In this review, we will be comparing SuperCube 4000 and ASW610, two Powered Subwoofer speakers from Definitive Technology and Bowers Wilkins. 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 B&W ASW610 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 B&W ASW610 have a single woofer setup however the DT SuperCube 4000's woofer is 8-inch whereas the B&W ASW610 features a 10-inch woofer.
Frequency Response
SuperCube 4000 has a frequency range of 16-200 Hz whereas ASW610 has a frequency range of 27-140 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 ASW610's min frequency of 27Hz.
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 DT SuperCube 4000 has a Passive Radiator type cabinet. 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. On the other hand the B&W ASW610 have Acoustic Suspension type enclosure. 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.
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 B&W ASW610'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 B&W ASW610 has external dimensions of 321.0 x 312.0 x 394.0mm (12-5/8 x 12-1/4 x 15-1/2inch).
B&W ASW610 is clearly the larger of the two speakers. Its body is 31mm wider, 19mm taller and 76mm deeper than DT SuperCube 4000.

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 B&W ASW610 is approximately 1229.3cm2 / 190.5inch2. The SuperCube 4000 requires 27% less surface area than the ASW610 which gives it a small advantage 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 B&W ASW610 weighs 12.55kg / 27.6lbs. This makes the ASW610 10% heavier than the SuperCube 4000.
Here is a comparison of how SuperCube 4000 and ASW610'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.
B&W ASW610 needs about 38% more floor area. B&W ASW610 stands 76mm further into the room. B&W ASW610 is 19mm taller.

A passive radiator subwoofer against a sealed 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 | A | DT SuperCube 4000 goes deeper - 16Hz against 27Hz. 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 200W RMS, about 7.8dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | B&W ASW610 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 | DT SuperCube 4000 is passive radiator - a passive radiator behaves like a port without the pipe noise, and suits a slim cabinet; B&W ASW610 is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Cabinet size | depends | DT SuperCube 4000 is about 32% 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 | A | DT SuperCube 4000 carries 3 years on parts against 2 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | A | DT SuperCube 4000 costs less - $799 against $899, about 11% less. |
A DT SuperCube 4000 B B&W ASW610
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 B&W ASW610 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, B&W ASW610 is usually the easier one to make sound right. 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.
