In this review, we will be comparing PB-1000 and DB3D, two Powered Subwoofer speakers from SVS and Bowers Wilkins. 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 B&W DB3D 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 B&W DB3D 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 and B&W DB3D have a totally different setup: the SVS PB-1000 features 1 x 10-inch drivers whereas the DB3D features 2 x 8-inch drivers.
Frequency Response
PB-1000 has a frequency range of 19-270 Hz whereas DB3D has a frequency range of 10-350Hz. With a minimum frequency of 10Hz, the DB3D can go significantly deeper on the low side and provide stronger bass compared to 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 B&W DB3D 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's and B&W DB3D'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 B&W DB3D has external dimensions of ( ) .
SVS PB-1000 is clearly the larger of the two speakers. Its body is 381mm wider, 480mm taller and 532mm deeper than B&W DB3D.
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 B&W DB3D weighs 25.05kg / 55.1lbs. This makes the DB3D 20% heavier than the PB-1000.
Here is a comparison of how PB-1000 and DB3D's weights compare with the average, max and min weights in Powered Subwoofer class.
