In this review, we will be comparing PB-1000 Pro 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 PB-1000 Pro and KEF KC62 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 PB-1000 Pro and KEF KC62 compare and hopefully end up with enough arguments to decide which one of these subwoofers is the better choice for you.

Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.SVS PB-1000 Pro and KEF KC62 have a totally different setup: the SVS PB-1000 Pro features 1 x 12-inch drivers whereas the KC62 features 2 x 6.5-inch drivers.
Frequency Response
PB-1000 Pro has a frequency range of 17-260 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 PB-1000 Pro'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
The SVS PB-1000 Pro has a Bass Reflex type cabinet. Bass Reflex type subwoofers (aka Ported, Vented or Reflex Port) have enclosures that uses a port, hole or vent cut into the cabinet. Ported designs are generally more efficient than the Sealed designs. On the other hand the KEF KC62 have Acoustic Suspension type enclosure. 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
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 PB-1000 Pro's and KEF KC62's external dimensions. SVS PB-1000 Pro has external dimensions of 479.0 x 380.0 x 509.0mm ( 18-13/16inch x 15inch x 20-15/16inch ) 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 PB-1000 Pro is clearly the larger of the two speakers. Its body is 122mm wider, 234mm taller and 228mm deeper than KEF KC62.
Below you can see the front view size comparison of SVS PB-1000 Pro and KEF KC62 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 PB-1000 Pro is approximately 1934.2cm2 / 299.8inch2 and base area of the KEF KC62 is approximately 725.0cm2 / 112.4inch2. The PB-1000 Pro requires 167% more surface area than the KC62 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 PB-1000 Pro weighs 19.30kg / 42.5lbs and the KEF KC62 weighs 14.05kg / 30.9lbs. This makes the PB-1000 Pro 37% heavier than the KC62.
