In this review, we will be comparing PC-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 PC-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 PC-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.

Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Both SVS PC-2000and KEF KUBE 10b have a single woofer setup however the SVS PC-2000's woofer is 12-inch whereas the KEF KUBE 10b features a 10-inch woofer.
Frequency Response
PC-2000 has a frequency range of 16-260 Hz whereas KUBE 10b has a frequency range of 24-140 Hz. With a minimum frequency of 16Hz, the PC-2000 can go significantly deeper on the low side and provide stronger bass compared to the KUBE 10b's min frequency of 24Hz.
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 PC-2000 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 KUBE 10b 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 PC-2000's and KEF KUBE 10b's external dimensions. SVS PC-2000 has external dimensions of 872.0 x 422.0 x 422.0mm ( 34-5/16 x 16-5/8 x 16-5/8inch) 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) .
SVS PC-2000 is clearly the larger of the two speakers. Its body is 66mm wider, 500mm taller and 25mm deeper than KEF KUBE 10b.
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 PC-2000 is approximately 1780.8cm2 / 276.0inch2 and base area of the KEF KUBE 10b is approximately 1413.3cm2 / 219.1inch2. The PC-2000 requires 26% 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 PC-2000 weighs 22.70kg / 49.9lbs and the KEF KUBE 10b weighs 17.50kg / 38.5lbs. This makes the PC-2000 30% heavier than the KUBE 10b.
Here is a comparison of how PC-2000 and KUBE 10b's weights compare with the average, max and min weights in Powered Subwoofer class.
