Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Klipsch SPL-100 and KEF KF92 have a totally different setup: the Klipsch SPL-100 features 1 x 10-inch drivers whereas the KF92 features 2 x 9-inch drivers.
Frequency Response
SPL-100 has a frequency range of 27-125 Hz whereas KF92 has a frequency range of 11-200 Hz. With a minimum frequency of 11Hz, the KF92 can go significantly deeper on the low side and provide stronger bass compared to the SPL-100's min frequency of 27Hz.
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.

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 KEF KF92 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 KEF KF92'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 KEF KF92 has external dimensions of 353.0 x 331.0 x 362.0mm ( 13-7/8 x 13 x 14-1/4inch) .
Klipsch SPL-100 is clearly the larger of the two speakers. Its body is 27mm wider, 65mm taller and 116mm deeper than KEF KF92.
Below you can see the front view size comparison of Klipsch SPL-100 and KEF KF92 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 KEF KF92 is approximately 1198.2cm2 / 185.7inch2. The SPL-100 requires 43% more surface area than the KF92 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 KEF KF92 weighs 20.05kg / 44.1lbs. This makes the KF92 19% heavier than the SPL-100.
