In this review, we will be comparing PB-1000 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 PB-1000 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.Both SVS PB-1000and Klipsch R-120SW have a single woofer setup however the SVS PB-1000's woofer is 10-inch whereas the Klipsch R-120SW features a 12-inch woofer.
Frequency Response
PB-1000 has a frequency range of 19-270 Hz whereas R-120SW has a frequency range of 29-120 Hz. With a minimum frequency of 19Hz, the PB-1000 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 PB-1000 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 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 PB-1000's and Klipsch R-120SW's external dimensions. SVS PB-1000 has external dimensions of 480.0 x 381.0 x 532.0mm (18-7/8 x 15 x 20-15/16inch) 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).
Klipsch R-120SW is 23mm narrower and 57mm shorter than SVS PB-1000 but they have the same thickness of 532.0mm.

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 PB-1000 is approximately 2026.9cm2 / 314.2inch2 and base area of the Klipsch R-120SW is approximately 1904.6cm2 / 295.2inch2. The PB-1000 requires 6% more surface area than the R-120SW 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 SVS PB-1000 weighs 20.91kg / 46lbs and the Klipsch R-120SW weighs 14.09kg / 31lbs. This makes the PB-1000 48% heavier than the R-120SW.
Here is a comparison of how PB-1000 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.
Near-identical footprints. SVS PB-1000 is 57mm taller.

No single best subwoofer here. Your room, where the box can physically go, and whether this is mainly for films or mainly for music will settle it long before the specs do.
| Area | Better | Why |
|---|
| Bass depth | A | SVS PB-1000 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 PB-1000 has the bigger amplifier - 300W against 200W RMS, about 1.8dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | Klipsch R-120SW 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. |
| Speaker-level inputs | A | SVS PB-1000 takes a speaker-level connection as well as line level. That is what lets it work with an integrated amplifier or a vintage receiver that has no subwoofer output at all. |
| Cabinet size | depends | Klipsch R-120SW 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 | A | SVS PB-1000 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 | SVS PB-1000 costs less - $499 against $599, about 17% less. |
A SVS PB-1000 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 PB-1000 is the easier recommendation: it leads on most of the measured areas and costs less. Take Klipsch R-120SW if one of the "depends" rows describes your room. Check your amplifier first: if it has no subwoofer or preamp output, SVS PB-1000 is the only one of these two you can connect at all.
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.
