In this review, we will be comparing SB-2000 and KUBE 10b, two Powered Subwoofer speakers from SVS and KEF. 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 SVS SB-2000 and KEF KUBE 10b first before getting into our more detailed comparison.
In the following sections, we will get into details in order to better understand how the SVS SB-2000 and KEF KUBE 10b compare and hopefully end up with enough arguments to decide which one of these subwoofers is the better choice for you.

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's and KEF KUBE 10b's external dimensions. 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) 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) .

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 is approximately 1730.4cm2 / 268.2inch2 and base area of the KEF KUBE 10b is approximately 1413.3cm2 / 219.1inch2. The SB-2000 requires 22% 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 weighs 15.82kg / 34.8lbs and the KEF KUBE 10b weighs 17.50kg / 38.5lbs. This makes the KUBE 10b 11% heavier than the SB-2000.
Here is a comparison of how SB-2000 and KUBE 10b's weights compare with the average, max and min weights in Powered Subwoofer class.
