Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Both SVS PB-4000and PSB SubSeries 350 have a single woofer setup however the SVS PB-4000's woofer is 13.5-inch whereas the PSB SubSeries 350 features a 12-inch woofer.

Cabinet Type
The SVS PB-4000 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 PSB SubSeries 350 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-4000's and PSB SubSeries 350's external dimensions. SVS PB-4000 has external dimensions of 596.0 x 521.0 x 762.0mm ( 23-7/16 x 20-1/2 x 30inch) whereas PSB SubSeries 350 has external dimensions of 407.0 x 394.0 x 445.0mm ( 16 x 15-1/2 x 17-1/2inch) .
SVS PB-4000 is clearly the larger of the two speakers. Its body is 127mm wider, 189mm taller and 317mm deeper than PSB SubSeries 350.
Below you can see the front view size comparison of SVS PB-4000 and PSB SubSeries 350 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 PB-4000 is approximately 3970.0cm2 / 615.4inch2 and base area of the PSB SubSeries 350 is approximately 1753.3cm2 / 271.8inch2. The PB-4000 requires 126% more surface area than the SubSeries 350 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-4000 weighs 69.64kg / 153.2lbs and the PSB SubSeries 350 weighs 23.18kg / 51lbs. This makes the PB-4000 200% heavier than the SubSeries 350.
