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-4000's and SVS PB-1000's external dimensions. SVS SB-4000 has external dimensions of 466.0 x 453.0 x 532.0mm ( 18-5/16 x 17-13/16 x 20-15/16inch) 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) .
Below you can see the front view size comparison of SVS SB-4000 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-4000 is approximately 2410.0cm2 / 373.6inch2 and base area of the SVS PB-1000 is approximately 2026.9cm2 / 314.2inch2. The SB-4000 requires 19% more surface area than the PB-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 SB-4000 weighs 46.50kg / 102.3lbs and the SVS PB-1000 weighs 20.91kg / 46lbs. This makes the SB-4000 122% heavier than the PB-1000.
Here is a comparison of how SB-4000 and PB-1000's weights compare with the average, max and min weights in Powered Subwoofer class.
