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

The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Both Focal Sub Airand DT SuperCube 2000 have a single woofer setup however the Focal Sub Air's woofer is 8-inch whereas the DT SuperCube 2000 features a 7.5-inch woofer.
Frequency Response
Sub Air has a frequency range of 40-200 Hz whereas SuperCube 2000 has a frequency range of 20-200 Hz. With a minimum frequency of 20Hz, the SuperCube 2000 can go significantly deeper on the low side and provide stronger bass compared to the Sub Air's min frequency of 40Hz.
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 Focal Sub Air has a Bass Reflex type cabinet. Bass Reflex type subwoofers (aka Ported, Vented or Reflex Port) have enclosures that uses a port, hole or vent cut into the cabinet. Ported designs are generally more efficient than the Sealed designs. On the other hand the DT SuperCube 2000 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
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 Focal Sub Air's and DT SuperCube 2000's external dimensions. Focal Sub Air has external dimensions of 410.0 x 362.0 x 162.0mm ( 16-1/8 x 14-1/4 x 6-3/8inch) 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 101mm narrower and 135mm shorter than Focal Sub Air but it is also 159mm deeper.

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 Focal Sub Air is approximately 586.4cm2 / 90.9inch2 and base area of the DT SuperCube 2000 is approximately 837.8cm2 / 129.9inch2. The Sub Air requires 30% less surface area than the SuperCube 2000 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 Focal Sub Air weighs 7.73kg / 17lbs and the DT SuperCube 2000 weighs 11.36kg / 25lbs. This makes the SuperCube 2000 47% heavier than the Sub Air.
