In this review, we will be comparing R212s and R-121SW, two Powered Subwoofer speakers from Perlisten and Klipsch. Being Powered subwoofers, they both have built-in amplifiers so you don't need an external power amp or an integrated amp to power them. Let's have a brief look at the main features of Perlisten R212s and Klipsch R-121SW 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 R212s and Klipsch R-121SW have a totally different setup: the Perlisten R212s features x -inch drivers whereas the R-121SW features 1 x 12-inch drivers.
Frequency Response
R212s has a frequency range of 20-256 Hz whereas R-121SW has a frequency range of 28-120 Hz. With a minimum frequency of 20Hz, the R212s can go significantly deeper on the low side and provide stronger bass compared to the R-121SW's min frequency of 28Hz.
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 R212s's and Klipsch R-121SW's external dimensions. Perlisten R212s has external dimensions of 599.9 x 410.0 x 500.1mm (23.62 x 16.14 x 19.69inch) whereas Klipsch R-121SW has external dimensions of 423.0 x 407.0 x 532.0mm (16-5/8inch x 16inch x 20-15/16inch).
Klipsch R-121SW is 3mm narrower and 176.9mm shorter than Perlisten R212s but it is also 31.9mm deeper.
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 R212s is approximately 2050.4cm2 / 317.8inch2 and base area of the Klipsch R-121SW is approximately 2165.2cm2 / 335.6inch2. The R212s requires 5% less surface area than the R-121SW 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 Perlisten R212s weighs 48.20kg / 106lbs and the Klipsch R-121SW weighs 16.00kg / 35.2lbs. This makes the R212s 201% heavier than the R-121SW.
Here is a comparison of how R212s and R-121SW's weights compare with the average, max and min weights in Powered Subwoofer class.
