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-4000's and SVS SB-2000's external dimensions. SVS SB-4000 has external dimensions of 466.0 x 453.0 x 532.0mm ( 18-5/16 x 17-13/16 x 20-15/16inch) whereas SVS SB-2000 has external dimensions of 372.0 x 362.0 x 478.0mm ( 14-5/8 x 14-1/4 x 18-13/16inch) .
SVS SB-4000 is clearly the larger of the two speakers. Its body is 91mm wider, 94mm taller and 54mm deeper than SVS SB-2000.
Below you can see the front view size comparison of SVS SB-4000 and SVS SB-2000 in scale.

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 SVS SB-4000 is approximately 2410.0cm2 / 373.6inch2 and base area of the SVS SB-2000 is approximately 1730.4cm2 / 268.2inch2. The SB-4000 requires 39% more surface area than the SB-2000 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 SVS SB-4000 weighs 46.50kg / 102.3lbs and the SVS SB-2000 weighs 15.82kg / 34.8lbs. This makes the SB-4000 194% heavier than the SB-2000.
Here is a comparison of how SB-4000 and SB-2000's weights compare with the average, max and min weights in Powered Subwoofer class.
