Cabinet Type
The Klipsch R-101SW 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.

Sealed designs helps to provide more accurate and tight bass responses compared to ported designs.
Physical Specs

In this section, we are going to compare Klipsch R-101SW's and PSB SubSeries 350's external dimensions. Klipsch R-101SW has external dimensions of 370.0 x 358.0 x 529.0mm ( 14-9/16inch x 14-1/16inch x 20-13/16inch ) 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) .
Klipsch R-101SW is 36mm narrower and 37mm shorter than PSB SubSeries 350 but it is also 84mm deeper.
