In this review, we will be comparing SB-2000 and R-120SW, two Powered Subwoofer speakers from SVS 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 SVS SB-2000 and Klipsch R-120SW 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.SVS SB-2000and Klipsch R-120SW have the same driver set up: Both subwoofers have 1 x 12" drivers.
Frequency Response
SB-2000 has a frequency range of 19-220 Hz whereas R-120SW has a frequency range of 29-120 Hz. With a minimum frequency of 19Hz, the SB-2000 can go significantly deeper on the low side and provide stronger bass compared to the R-120SW's min frequency of 29Hz.
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 SVS SB-2000 has a Acoustic Suspension type cabinet. 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. On the other hand the Klipsch R-120SW have Bass reflex type enclosure.
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 SVS SB-2000's and Klipsch R-120SW's external dimensions. SVS SB-2000 has external dimensions of 372.0 x 362.0 x 478.0mm (14-5/8 x 14-1/4 x 18-13/16inch) whereas Klipsch R-120SW has external dimensions of 423.0 x 358.0 x 532.0mm (16-5/8 x 14-1/16 x 20-15/16inch).
SVS SB-2000 is 51mm shorter and 54mm less deeper than Klipsch R-120SW but it is also 4mm wider.
Below you can see the front view size comparison of SVS SB-2000 and Klipsch R-120SW in scale.

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 SVS SB-2000 is approximately 1730.4cm2 / 268.2inch2 and base area of the Klipsch R-120SW is approximately 1904.6cm2 / 295.2inch2. The SB-2000 requires 9% less surface area than the R-120SW 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 SVS SB-2000 weighs 15.82kg / 34.8lbs and the Klipsch R-120SW weighs 14.09kg / 31lbs. This makes the SB-2000 12% heavier than the R-120SW.
Here is a comparison of how SB-2000 and R-120SW'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-120SW needs about 10% more floor area. Klipsch R-120SW stands 54mm further into the room. Klipsch R-120SW is 51mm taller.

A sealed subwoofer against a ported 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 | A | SVS SB-2000 goes deeper - 19Hz against 29Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | A | SVS SB-2000 has the bigger amplifier - 500W against 200W RMS, about 4dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | evenly matched | Near-identical radiating area (12" against 12"). |
| Enclosure | depends | SVS SB-2000 is sealed - a sealed box rolls off gently and is usually the easier one to integrate in a small or awkward room; Klipsch R-120SW is ported - a ported box gives more output low down for its size, at the cost of a steeper roll-off below tuning. Neither is better in the abstract; ported tends to suit films and sealed tends to suit music, and both generalisations have exceptions. |
| Cabinet size | depends | SVS SB-2000 is about 20% 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 | A | SVS SB-2000 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 | evenly matched | Priced within a few per cent of each other. |
A SVS SB-2000 B Klipsch R-120SW
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?
SVS SB-2000 has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is. Films or music? If this is mainly a home cinema, Klipsch R-120SW will hit harder for the money; if it is mainly for music in a normal-sized room, SVS SB-2000 is usually the easier one to make sound right.
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.
