In this review, we will be comparing SB-3000 R|Evolution and KC62, 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-3000 R|Evolution and KEF KC62 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.SVS SB-3000 R|Evolution and KEF KC62 have a totally different setup: the SVS SB-3000 R|Evolution features 1 x 13-inch drivers whereas the KC62 features 2 x 6.5-inch drivers.
Frequency Response
SB-3000 R|Evolution has a frequency range of 17-230 Hz whereas KC62 has a frequency range of 11-200 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-3000 R|Evolution's min frequency of 17Hz.
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 SVS SB-3000 R|Evolution and KEF KC62 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 SVS SB-3000 R|Evolution's and KEF KC62's external dimensions. SVS SB-3000 R|Evolution has external dimensions of 396.0 x 386.0 x 427.0mm (15-9/16 x 15-3/16 x 16-13/16inch) whereas 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).
SVS SB-3000 R|Evolution is clearly the larger of the two speakers. Its body is 128mm wider, 151mm taller and 146mm deeper than KEF KC62.
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-3000 R|Evolution is approximately 1648.2cm2 / 255.5inch2 and base area of the KEF KC62 is approximately 725.0cm2 / 112.4inch2. The SB-3000 R|Evolution requires 127% more surface area than the KC62 which gives it a small disadvantage on placement in tight spaces.
