In this review, we will be comparing SuperCube 2000 and DB4S, 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 2000 and B&W DB4S first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how the DT SuperCube 2000 and B&W DB4S compare and hopefully end up with enough arguments to decide which one of these subwoofers is the better choice for you.

Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Both DT SuperCube 2000and B&W DB4S have a single woofer setup however the DT SuperCube 2000's woofer is 7.5-inch whereas the B&W DB4S features a 10-inch woofer.
Frequency Response
SuperCube 2000 has a frequency range of 20-200 Hz whereas DB4S has a frequency range of 10-350 Hz. With a minimum frequency of 10Hz, the DB4S can go significantly deeper on the low side and provide stronger bass compared to 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
The DT SuperCube 2000 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 DB4S 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
Size of a speaker can sometimes become 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 2000's and B&W DB4S's external dimensions. 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) whereas B&W DB4S has external dimensions of 375.0 x 362.0 x 434.0mm ( 14-3/4 x 14-1/4 x 17-1/16inch) .
B&W DB4S is clearly the larger of the two speakers. Its body is 101mm wider, 100mm taller and 113mm deeper than DT SuperCube 2000.
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 2000 is approximately 837.8cm2 / 129.9inch2 and base area of the B&W DB4S is approximately 1571.1cm2 / 243.5inch2. The SuperCube 2000 requires 47% less surface area than the DB4S 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 2000 weighs 11.36kg / 25lbs and the B&W DB4S weighs 26.05kg / 57.3lbs. This makes the DB4S 129% heavier than the SuperCube 2000.
Here is a comparison of how SuperCube 2000 and DB4S's weights compare with the average, max and min weights in Powered Subwoofer class.
