Frequency Response
R-101SW has a frequency range of 29.5-160 Hz whereas PB-1000 has a frequency range of 19-270 Hz. With a minimum frequency of 19Hz, the PB-1000 can go significantly deeper on the low side and provide stronger bass compared to the R-101SW's min frequency of 30Hz.
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.

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 R-101SW's and SVS PB-1000'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 SVS PB-1000 has external dimensions of 480.0 x 381.0 x 532.0mm ( 18-7/8 x 15 x 20-15/16inch) .
SVS PB-1000 is clearly the larger of the two speakers. Its body is 23mm wider, 110mm taller and 3mm deeper than Klipsch R-101SW.

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 R-101SW is approximately 1893.8cm2 / 293.5inch2 and base area of the SVS PB-1000 is approximately 2026.9cm2 / 314.2inch2. The R-101SW requires 7% less surface area than the PB-1000 which gives it a small advantage 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 R-101SW weighs 13.91kg / 30.6lbs and the SVS PB-1000 weighs 20.91kg / 46lbs. This makes the PB-1000 50% heavier than the R-101SW.
Here is a comparison of how R-101SW and PB-1000's weights compare with the average, max and min weights in Powered Subwoofer class.
