Cabinet Type
The Audioengine S6 has a Acoustic Suspension type cabinet. Acoustic Suspension aka Sealed type subwoofers have enclosures that are sealed hence no ports or holes exists on the 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.
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 Audioengine S6's and Klipsch R-101SW's external dimensions. Audioengine S6 has external dimensions of 250.0 x 221.0 x 281.0mm ( 9-13/16inch x 8-11/16inch x 11-1/16inch ) whereas 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 ) .
Klipsch R-101SW is clearly the larger of the two speakers. Its body is 137mm wider, 120mm taller and 248mm deeper than Audioengine S6.
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 Audioengine S6 is approximately 621.0cm2 / 96.3inch2 and base area of the Klipsch R-101SW is approximately 1893.8cm2 / 293.5inch2. The S6 requires 67% less surface area than the R-101SW 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 Audioengine S6 weighs 7.00kg / 15.4lbs and the Klipsch R-101SW weighs 13.91kg / 30.6lbs. This makes the R-101SW 99% heavier than the S6.
Here is a comparison of how S6 and R-101SW's weights compare with the average, max and min weights in Powered Subwoofer class.
