Cabinet Type
The Klipsch RP-1200SW 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 250 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 Klipsch RP-1200SW's and PSB SubSeries 250's external dimensions. Klipsch RP-1200SW has external dimensions of 482.0 x 432.0 x 659.0mm ( 18-15/16inch x 17inch x 25-15/16inch ) whereas PSB SubSeries 250 has external dimensions of 362.0 x 348.0 x 397.0mm ( 14-1/4 x 13-11/16 x 15-5/8inch) .
Klipsch RP-1200SW is clearly the larger of the two speakers. Its body is 84mm wider, 120mm taller and 262mm deeper than PSB SubSeries 250.

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 Klipsch RP-1200SW is approximately 2846.9cm2 / 441.3inch2 and base area of the PSB SubSeries 250 is approximately 1381.6cm2 / 214.1inch2. The RP-1200SW requires 106% more surface area than the SubSeries 250 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 Klipsch RP-1200SW weighs 31.18kg / 68.6lbs and the PSB SubSeries 250 weighs 19.09kg / 42lbs. This makes the RP-1200SW 63% heavier than the SubSeries 250.
