Cabinet Type
The Klipsch R-112SW 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.

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.

In this section, we are going to compare Klipsch R-112SW's and KEF KUBE 10b's external dimensions. Klipsch R-112SW has external dimensions of 442.0 x 391.0 x 532.0mm ( 17-3/8 x 15-3/8 x 20-15/16inch) whereas KEF KUBE 10b has external dimensions of 372.0 x 356.0 x 397.0mm ( 14-5/8 x 14 x 15-5/8inch) .
Klipsch R-112SW is clearly the larger of the two speakers. Its body is 35mm wider, 70mm taller and 135mm deeper than KEF KUBE 10b.

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-112SW is approximately 2080.1cm2 / 322.4inch2 and base area of the KEF KUBE 10b is approximately 1413.3cm2 / 219.1inch2. The R-112SW requires 47% more surface area than the KUBE 10b which gives it a small disadvantage on placement in tight spaces.
