In this review, we will be comparing R-101SW and PB-2000 Pro, two Powered Subwoofer speakers from Klipsch and SVS. 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 Klipsch R-101SW and SVS PB-2000 Pro 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.Both Klipsch R-101SWand SVS PB-2000 Pro have a single woofer setup however the Klipsch R-101SW's woofer is 10-inch whereas the SVS PB-2000 Pro features a 12-inch woofer.
Frequency Response
R-101SW has a frequency range of 29.5-160 Hz whereas PB-2000 Pro has a frequency range of 16-290 Hz. With a minimum frequency of 16Hz, the PB-2000 Pro 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 Klipsch R-101SW and SVS PB-2000 Pro 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 Klipsch R-101SW's and SVS PB-2000 Pro's external dimensions. 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) whereas SVS PB-2000 Pro has external dimensions of 534.0 x 442.0 x 609.0mm (21 x 17-3/8 x 23-15/16inch).
SVS PB-2000 Pro is clearly the larger of the two speakers. Its body is 84mm wider, 164mm taller and 80mm deeper than Klipsch R-101SW.

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 R-101SW is approximately 1893.8cm2 / 293.5inch2 and base area of the SVS PB-2000 Pro is approximately 2691.8cm2 / 417.2inch2. The R-101SW requires 30% less surface area than the PB-2000 Pro 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 Klipsch R-101SW weighs 13.91kg / 30.6lbs and the SVS PB-2000 Pro weighs 29.45kg / 64.8lbs. This makes the PB-2000 Pro 112% heavier than the R-101SW.
Here is a comparison of how R-101SW and PB-2000 Pro's weights compare with the average, max and min weights in Powered Subwoofer class.

Size, drawn to scale
Both subwoofers 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 floor and pushed back to the same wall, so the bigger one visibly takes more of the room.
SVS PB-2000 Pro needs about 42% more floor area. SVS PB-2000 Pro stands 80mm further into the room. SVS PB-2000 Pro is 164mm taller.

Different price classes - SVS PB-2000 Pro costs roughly 2.2x what Klipsch R-101SW does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | B | SVS PB-2000 Pro goes deeper - 16Hz against 30Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | B | SVS PB-2000 Pro has the bigger amplifier - 550W against 150W RMS, about 5.6dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | SVS PB-2000 Pro moves more air: 12" against 10" is 1.44x the cone area, not the 1.2x the diameters suggest. More area means the same output with less excursion, and less distortion with it. |
| Enclosure | evenly matched | Both are ported designs, so they roll off in much the same way. |
| Wireless option | depends | Only SVS PB-2000 Pro offers a wireless link (as a paid option). It decides where the sub can go if you cannot run a cable, and is worth nothing if you can. |
| Cabinet size | depends | Klipsch R-101SW is about 51% 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. |
| Warranty | B | SVS PB-2000 Pro carries 5 years on parts against 2 years. A subwoofer amplifier works harder than anything else in the system, so this is not a throwaway line. |
| Price | A | Klipsch R-101SW costs less - $499 against $1,100, about 55% less. |
A Klipsch R-101SW B SVS PB-2000 Pro
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?
The usual trade-off: SVS PB-2000 Pro measures better, Klipsch R-101SW costs about 55% less. In a normal room, placement will make a bigger difference than the gap between these two. 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 $1,100 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.
