In this review, we will be comparing SB-1000 and PB-1000, two Powered Subwoofer speakers by 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 SVS SB-1000 and SVS PB-1000 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-1000 and SVS PB-1000 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 SB-1000and SVS PB-1000 have a single woofer setup however the SVS SB-1000's woofer is 12-inch whereas the SVS PB-1000 features a 10-inch woofer.
Frequency Response
SB-1000 has a frequency range of 24-260 Hz whereas PB-1000 has a frequency range of 19-270 Hz. With a minimum frequency of 19Hz, the PB-1000 can go significantly deeper on the low side and provide stronger bass compared to the SB-1000'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 SB-1000 has a Acoustic Suspension type cabinet. 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. On the other hand the SVS PB-1000 have Bass Reflex type enclosure. 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.
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-1000's and SVS PB-1000's external dimensions. SVS SB-1000 has external dimensions of 343.0 x 332.0 x 397.0mm ( 13-1/2 x 13-1/16 x 15-5/8inch) whereas SVS PB-1000 has external dimensions of 480.0 x 381.0 x 532.0mm ( 18-7/8 x 15 x 20-15/16inch) .
SVS PB-1000 is clearly the larger of the two speakers. Its body is 49mm wider, 137mm taller and 135mm deeper than SVS SB-1000.
Below you can see the front view size comparison of SVS SB-1000 and SVS PB-1000 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 SB-1000 is approximately 1318.0cm2 / 204.3inch2 and base area of the SVS PB-1000 is approximately 2026.9cm2 / 314.2inch2. The SB-1000 requires 35% less surface area than the PB-1000 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 SVS SB-1000 weighs 12.27kg / 27lbs and the SVS PB-1000 weighs 20.91kg / 46lbs. This makes the PB-1000 70% heavier than the SB-1000.
Here is a comparison of how SB-1000 and PB-1000's weights compare with the average, max and min weights in Powered Subwoofer class.
