Cabinet Type
The Klipsch SPL-100 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 Dynaudio Sub 3 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 SPL-100's and Dynaudio Sub 3's external dimensions. Klipsch SPL-100 has external dimensions of 418.0 x 358.0 x 478.0mm ( 16-7/16 x 14-1/16 x 18-13/16inch) whereas Dynaudio Sub 3 has external dimensions of 277.0 x 269.0 x 366.0mm ( 10-7/8 x 10-9/16 x 14-3/8inch) .
Klipsch SPL-100 is clearly the larger of the two speakers. Its body is 89mm wider, 141mm taller and 112mm deeper than Dynaudio Sub 3.
Below you can see the front view size comparison of Klipsch SPL-100 and Dynaudio Sub 3 in scale.

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 SPL-100 is approximately 1711.2cm2 / 265.2inch2 and base area of the Dynaudio Sub 3 is approximately 984.5cm2 / 152.6inch2. The SPL-100 requires 74% more surface area than the Sub 3 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 SPL-100 weighs 16.82kg / 37lbs and the Dynaudio Sub 3 weighs 10.50kg / 23.1lbs. This makes the SPL-100 60% heavier than the Sub 3.
