In this review, we will be comparing KC62 and SB-2000 Pro, two Powered Subwoofer speakers from KEF and SVS. 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 KEF KC62 and SVS SB-2000 Pro first before getting into our more detailed comparison.
The sections below take each area in turn: driver and amplifier, frequency response, physical size and connectivity.

Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.KEF KC62 and SVS SB-2000 Pro have a totally different setup: the KEF KC62 features 2 x 6.5-inch drivers whereas the SB-2000 Pro features 1 x 12-inch drivers.
Frequency Response
KC62 has a frequency range of 11-200 Hz whereas SB-2000 Pro has a frequency range of 19-240 Hz. With a minimum frequency of 11Hz, the KC62 can go significantly deeper on the low side and provide stronger bass compared to the SB-2000 Pro's min frequency of 19Hz.
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
Both KEF KC62 and SVS SB-2000 Pro have Acoustic Suspension type cabinets. 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.
Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare KEF KC62's and SVS SB-2000 Pro's external dimensions. KEF KC62 has external dimensions of 245.0 x 258.0 x 281.0mm (9-5/8inch x 10-1/8inch x 11-1/16inch) whereas 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).
SVS SB-2000 Pro is clearly the larger of the two speakers. Its body is 103mm wider, 125mm taller and 153mm deeper than KEF KC62.
Below you can see the front view size comparison of KEF KC62 and SVS SB-2000 Pro 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 KEF KC62 is approximately 725.0cm2 / 112.4inch2 and base area of the SVS SB-2000 Pro is approximately 1566.7cm2 / 242.8inch2. The KC62 requires 54% less surface area than the SB-2000 Pro 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 KEF KC62 weighs 14.05kg / 30.9lbs and the SVS SB-2000 Pro weighs 17.55kg / 38.6lbs. This makes the SB-2000 Pro 25% heavier than the KC62.
