In this review, we will be comparing PB-1000 and ProSub 1000, two Powered Subwoofer speakers from SVS and Definitive Technology. 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 and Definitive ProSub 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 PB-1000 and Definitive ProSub 1000 compare and hopefully end up with enough arguments to decide which one of these subwoofers is the better choice for you.

Frequency Response
PB-1000 has a frequency range of 19-270 Hz whereas ProSub 1000 has a frequency range of 18-150 Hz. With a minimum frequency of 18Hz, the ProSub 1000 can go slightly deeper then the PB-1000'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
The SVS PB-1000 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 Definitive ProSub 1000 have Passive Radiator type enclosure. Passive Radiator type subwoofers sports a non-powered cone that moves in response to the main woofer to move air out in order to generate stronger bass in a smaller body compared to ported or 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 PB-1000's and Definitive ProSub 1000's external dimensions. SVS PB-1000 has external dimensions of 480.0 x 381.0 x 532.0mm ( 18-7/8 x 15 x 20-15/16inch) whereas Definitive ProSub 1000 has external dimensions of 366.0 x 307.0 x 486.0mm ( 14-3/8 x 12-1/16 x 19-1/8inch) .
SVS PB-1000 is clearly the larger of the two speakers. Its body is 74mm wider, 114mm taller and 46mm deeper than Definitive ProSub 1000.
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 is approximately 2026.9cm2 / 314.2inch2 and base area of the Definitive ProSub 1000 is approximately 1492.0cm2 / 231.3inch2. The PB-1000 requires 36% more surface area than the ProSub 1000 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 weighs 20.91kg / 46lbs and the Definitive ProSub 1000 weighs 14.09kg / 31lbs. This makes the PB-1000 48% heavier than the ProSub 1000.
Here is a comparison of how PB-1000 and ProSub 1000's weights compare with the average, max and min weights in Powered Subwoofer class.
