In this review, we will be comparing D215s and R-101SW, 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 D215s and Klipsch R-101SW 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 R-101SW have a totally different setup: the Perlisten D215s features x -inch drivers whereas the R-101SW features 1 x 10-inch drivers.
Frequency Response
D215s has a frequency range of 20-200 Hz whereas R-101SW has a frequency range of 29.5-160 Hz. With a minimum frequency of 20Hz, the D215s can go significantly deeper on the low side and provide stronger bass compared to the R-101SW's min frequency of 30Hz.
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
Both Perlisten D215s and Klipsch R-101SW have Bass Reflex type cabinets. 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.
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 R-101SW'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 R-101SW has external dimensions of 370.0 x 358.0 x 529.0mm (14-9/16inch x 14-1/16inch x 20-13/16inch).
Perlisten D215s is clearly the larger of the two speakers. Its body is 142.1mm wider, 434.9mm taller and 121.5mm deeper than Klipsch R-101SW.
Size, drawn to scale
Both speakers and both views share one scale, so everything here is directly comparable. Hover a box for its dimensions.
One scale for both, standing on the same surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Perlisten D215s needs about 72% more floor or shelf area. Perlisten D215s is 122mm deeper, so it stands that much further out from the wall. Perlisten D215s is 435mm taller.
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 R-101SW is approximately 1893.8cm2 / 293.5inch2. The D215s requires 72% more surface area than the R-101SW 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 R-101SW weighs 13.91kg / 30.6lbs. This makes the D215s 561% heavier than the R-101SW.
Here is a comparison of how D215s and R-101SW's weights compare with the average, max and min weights in Powered Subwoofer class.

Different price classes - Perlisten D215s costs roughly 22x what Klipsch R-101SW does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | A | Perlisten D215s goes deeper - 20Hz against 30Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Enclosure | evenly matched | Both are ported designs, so they roll off in much the same way. |
| Cabinet size | depends | Klipsch R-101SW is about 73% smaller by volume. In a subwoofer that is a real trade rather than a preference: box volume is how you get output low down without a bigger amplifier. |
| Price | B | Klipsch R-101SW costs less - $499 against $10,995, about 95% less. |
A Perlisten D215s B Klipsch R-101SW
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both subwoofers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
Perlisten D215s is ahead, but on only 1 of the measured areas, and it costs about 22x the price. Klipsch R-101SW is the sensible buy unless your room is large enough to need the extra. Two small subwoofers beat one big one in most rooms - a pair evens out the room modes in a way no single box can, whatever its specs. At $499 each, two Klipsch R-101SW cost about $998 against $10,995 for one of the other, which is worth a thought. If placement is the constraint - a corner, behind a sofa, under a desk - Klipsch R-101SW is the one that will actually go there, and a well-placed small subwoofer beats a badly-placed big one every time.
One thing outweighs everything above: where the subwoofer stands. Room modes can add or remove 10dB or more at a given seat, which is far larger than any difference on this page. Before spending more, try the sub in two or three positions - the crawl test, where you put it in the listening seat and crawl the room to find where the bass sounds best, costs nothing and usually beats an upgrade.
