Cabinet Type

The SVS SB-1000 Pro 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

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 SVS SB-1000 Pro's and DT SuperCube 4000's external dimensions. SVS SB-1000 Pro has external dimensions of 343.0 x 331.0 x 402.0mm ( 13-1/2inch x 13inch x 15-13/16inch ) 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) .

SVS SB-1000 Pro is clearly the larger of the two speakers. Its body is 50mm wider, 41mm taller and 84mm deeper than DT SuperCube 4000.

Below you can see the front view size comparison of SVS SB-1000 Pro and DT SuperCube 4000 in scale.
