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-2000 Pro's and KEF KUBE 10b's external dimensions. SVS SB-2000 Pro has external dimensions of 370.0 x 361.0 x 434.0mm ( 14-9/16 x 14-3/16 x 17-1/16inch) whereas KEF KUBE 10b has external dimensions of 372.0 x 356.0 x 397.0mm ( 14-5/8 x 14 x 15-5/8inch) .
KEF KUBE 10b is 5mm narrower and 37mm less deeper than SVS SB-2000 Pro but it is also 2mm taller.
Below you can see the front view size comparison of SVS SB-2000 Pro and KEF KUBE 10b 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-2000 Pro is approximately 1566.7cm2 / 242.8inch2 and base area of the KEF KUBE 10b is approximately 1413.3cm2 / 219.1inch2. The SB-2000 Pro requires 11% more surface area than the KUBE 10b 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-2000 Pro weighs 17.55kg / 38.6lbs and the KEF KUBE 10b weighs 17.50kg / 38.5lbs. This makes the SB-2000 Pro 0% heavier than the KUBE 10b.
Here is a comparison of how SB-2000 Pro and KUBE 10b's weights compare with the average, max and min weights in Powered Subwoofer class.
