Let's have a brief look at the main features of Perlisten D215s and Klipsch SPL-120 first before getting into our more detailed comparison.
The sections below take each area in turn: driver and amplifier, frequency response, physical size and connectivity.

Drivers
The efficiency of a subwoofer is directly proportional to the total radiating are squared hence the woofer quantity and diameter.Perlisten D215s and Klipsch SPL-120 have a totally different setup: the Perlisten D215s features x -inch drivers whereas the SPL-120 features 1 x 12-inch drivers.
Frequency Response
D215s has a frequency range of 20-200 Hz whereas SPL-120 has a frequency range of 24-125 Hz. With a minimum frequency of 20Hz, the D215s can go slightly deeper then the SPL-120's min frequency of 24Hz.
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
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Perlisten D215s's and Klipsch SPL-120's external dimensions. Perlisten D215s has external dimensions of 804.9 x 500.1 x 650.5mm (31.69 x 19.69 x 25.61inch) whereas Klipsch SPL-120 has external dimensions of 450.0 x 375.0 x 540.0mm (17-11/16 x 14-3/4 x 21-1/4inch).
Perlisten D215s is clearly the larger of the two speakers. Its body is 125.1mm wider, 354.9mm taller and 110.5mm deeper than Klipsch SPL-120.
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 Perlisten D215s is approximately 3253.2cm2 / 504.2inch2 and base area of the Klipsch SPL-120 is approximately 2025.0cm2 / 313.9inch2. The D215s requires 61% more surface area than the SPL-120 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 Perlisten D215s weighs 92.00kg / 202.4lbs and the Klipsch SPL-120 weighs 20.45kg / 45lbs. This makes the D215s 350% heavier than the SPL-120.
Here is a comparison of how D215s and SPL-120's weights compare with the average, max and min weights in Powered Subwoofer class.
