In this review, we will be comparing R-101SW and SB-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 SB-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 SB-2000 Pro have a single woofer setup however the Klipsch R-101SW's woofer is 10-inch whereas the SVS SB-2000 Pro features a 12-inch woofer.
Frequency Response
R-101SW has a frequency range of 29.5-160 Hz whereas SB-2000 Pro has a frequency range of 19-240 Hz. With a minimum frequency of 19Hz, the SB-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
The Klipsch R-101SW 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 SVS SB-2000 Pro 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
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 SB-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 SB-2000 Pro has external dimensions of 370.0 x 361.0 x 434.0mm (14-9/16 x 14-3/16 x 17-1/16inch).

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 SB-2000 Pro is approximately 1566.7cm2 / 242.8inch2. The R-101SW requires 21% more surface area than the SB-2000 Pro 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 R-101SW weighs 13.91kg / 30.6lbs and the SVS SB-2000 Pro weighs 17.55kg / 38.6lbs. This makes the SB-2000 Pro 26% heavier than the R-101SW.
Here is a comparison of how R-101SW and SB-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.
Klipsch R-101SW needs about 21% more floor area. Klipsch R-101SW stands 95mm further into the room.

A ported subwoofer against a sealed one. That is the most consequential line on this page: it decides how the bass rolls off, how it behaves in a small room, and how much output you get for the size of the box.
| Area | Better | Why |
|---|
| Bass depth | B | SVS SB-2000 Pro goes deeper - 19Hz 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 SB-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 SB-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 | depends | Klipsch R-101SW is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning; SVS SB-2000 Pro is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Wireless option | depends | Only SVS SB-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 | SVS SB-2000 Pro is about 17% 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 SB-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 $900, about 45% less. |
A Klipsch R-101SW B SVS SB-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 SB-2000 Pro measures better, Klipsch R-101SW costs about 45% less. In a normal room, placement will make a bigger difference than the gap between these two. Films or music? If this is mainly a home cinema, Klipsch R-101SW will hit harder for the money; if it is mainly for music in a normal-sized room, SVS SB-2000 Pro is usually the easier one to make sound right. 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 $900 for one of the other, which is worth a thought.
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.
