In this review, we will be comparing PC13-Ultra and SPL-100, 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 PC13-Ultra and Klipsch SPL-100 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 PC13-Ultraand Klipsch SPL-100 have a single woofer setup however the SVS PC13-Ultra's woofer is 13.5-inch whereas the Klipsch SPL-100 features a 10-inch woofer.
Frequency Response
PC13-Ultra has a frequency range of 15-200 Hz whereas SPL-100 has a frequency range of 27-125 Hz. With a minimum frequency of 15Hz, the PC13-Ultra can go significantly deeper on the low side and provide stronger bass compared to the SPL-100's min frequency of 27Hz.
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 SVS PC13-Ultra and Klipsch SPL-100 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 SVS PC13-Ultra's and Klipsch SPL-100's external dimensions. SVS PC13-Ultra has external dimensions of 1194.0 x 422.0 x 422.0mm (47 x 16-5/8 x 16-5/8inch) whereas Klipsch SPL-100 has external dimensions of 418.0 x 358.0 x 478.0mm (16-7/16 x 14-1/16 x 18-13/16inch).
Klipsch SPL-100 is 64mm narrower and 776mm shorter than SVS PC13-Ultra but it is also 56mm deeper.
Size, drawn to scale
Both speakers 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 surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Near-identical footprints. Klipsch SPL-100 is 56mm deeper, so it stands that much further out from the wall. SVS PC13-Ultra is 776mm 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 SVS PC13-Ultra is approximately 1780.8cm2 / 276.0inch2 and base area of the Klipsch SPL-100 is approximately 1711.2cm2 / 265.2inch2. The PC13-Ultra requires 4% more surface area than the SPL-100 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 PC13-Ultra weighs 40.80kg / 89.8lbs and the Klipsch SPL-100 weighs 16.82kg / 37lbs. This makes the PC13-Ultra 143% heavier than the SPL-100.
Here is a comparison of how PC13-Ultra and SPL-100's weights compare with the average, max and min weights in Powered Subwoofer class.

Two quite different sizes of subwoofer. Room volume decides this more than anything else on the page: a big driver in a small room is wasted, and a small one in a large room is worked to death.
| Area | Better | Why |
|---|
| Bass depth | A | SVS PC13-Ultra goes deeper - 15Hz against 27Hz. Under 20Hz is felt more than heard - the bottom of a pipe organ and the bottom of a film mix. |
| Amplifier power | A | SVS PC13-Ultra has the bigger amplifier - 1000W against 200W RMS, about 7dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | SVS PC13-Ultra moves more air: 13.5" against 10" is 1.82x the cone area, not the 1.35x 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. |
| Cabinet size | depends | Klipsch SPL-100 is about 66% 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 PC13-Ultra 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 | B | Klipsch SPL-100 costs less - $399 against $1,700, about 77% less. |
A SVS PC13-Ultra B Klipsch SPL-100
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 PC13-Ultra measures better, Klipsch SPL-100 costs about 77% 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 $399 each, two Klipsch SPL-100 cost about $798 against $1,700 for one of the other, which is worth a thought. If placement is the constraint - a corner, behind a sofa, under a desk - Klipsch SPL-100 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.
