In this review, we will be comparing RP-1200SW and PC-4000, 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 RP-1200SW and SVS PC-4000 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 RP-1200SWand SVS PC-4000 have a single woofer setup however the Klipsch RP-1200SW's woofer is 12-inch whereas the SVS PC-4000 features a 13.5-inch woofer.
Frequency Response
RP-1200SW has a frequency range of 16.5-138 Hz whereas PC-4000 has a frequency range of 17-200 Hz.
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 RP-1200SW and SVS PC-4000 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 RP-1200SW's and SVS PC-4000's external dimensions. Klipsch RP-1200SW has external dimensions of 482.0 x 432.0 x 659.0mm (18-15/16inch x 17inch x 25-15/16inch) whereas SVS PC-4000 has external dimensions of 1194.0 x 423.0 x 423.0mm (47 x 16-5/8 x 16-5/8inch).
SVS PC-4000 is 9mm narrower and 236mm less deeper than Klipsch RP-1200SW but it is also 712mm 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 Klipsch RP-1200SW is approximately 2846.9cm2 / 441.3inch2 and base area of the SVS PC-4000 is approximately 1789.3cm2 / 277.3inch2. The RP-1200SW requires 59% more surface area than the PC-4000 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 RP-1200SW weighs 31.18kg / 68.6lbs and the SVS PC-4000 weighs 42.00kg / 92.4lbs. This makes the PC-4000 35% heavier than the RP-1200SW.
Here is a comparison of how RP-1200SW and PC-4000's weights compare with the average, max and min weights in Powered Subwoofer class.

Different price classes - SVS PC-4000 costs roughly 2.2x what Klipsch RP-1200SW does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | evenly matched | Effectively the same reach (17Hz vs 17Hz). |
| Amplifier power | B | SVS PC-4000 has the bigger amplifier - 1200W against 400W RMS, about 4.8dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | SVS PC-4000 moves more air: 13.5" against 12" is 1.27x the cone area, not the 1.13x 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 Klipsch RP-1200SW 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. |
| Driver placement | depends | Klipsch RP-1200SW fires front and SVS PC-4000 fires down. A down-firing driver is more forgiving of a grille-less look and of a hard floor; a front-firing one is the safer choice on a thick carpet or a suspended timber floor. |
| Cabinet size | depends | Klipsch RP-1200SW is about 36% 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 | A | Klipsch RP-1200SW costs less - $999 against $2,200, about 55% less. |
A Klipsch RP-1200SW B SVS PC-4000
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 PC-4000 measures better, Klipsch RP-1200SW 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 $999 each, two Klipsch RP-1200SW cost about $1,998 against $2,200 for one of the other, which is worth a thought. If placement is the constraint - a corner, behind a sofa, under a desk - Klipsch RP-1200SW 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.
