In this review, we will be comparing R-100SW and S8, two Powered Subwoofer speakers from Klipsch and Audioengine. 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-100SW and Audioengine S8 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-100SWand Audioengine S8 have a single woofer setup however the Klipsch R-100SW's woofer is 10-inch whereas the Audioengine S8 features a 8-inch woofer.
Frequency Response
R-100SW has a frequency range of 32-120 Hz whereas S8 has a frequency range of 27-180 Hz. With a minimum frequency of 27Hz, the S8 can go significantly deeper on the low side and provide stronger bass compared to the R-100SW's min frequency of 32Hz.
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-100SW has a Bass reflex type cabinet. On the other hand the Audioengine S8 have Bass Reflex type enclosure. 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 R-100SW's and Audioengine S8's external dimensions. Klipsch R-100SW has external dimensions of 372.0 x 320.0 x 459.0mm (14-5/8 x 12-9/16 x 18-1/16inch) whereas Audioengine S8 has external dimensions of 334.0 x 293.0 x 337.0mm (13-1/8 x 11-1/2 x 13-1/4inch).
Klipsch R-100SW is clearly the larger of the two speakers. Its body is 27mm wider, 38mm taller and 122mm deeper than Audioengine S8.
Below you can see the front view size comparison of Klipsch R-100SW and Audioengine S8 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 Klipsch R-100SW is approximately 1468.8cm2 / 227.7inch2 and base area of the Audioengine S8 is approximately 987.4cm2 / 153.0inch2. The R-100SW requires 49% more surface area than the S8 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-100SW weighs 10.91kg / 24lbs and the Audioengine S8 weighs 13.64kg / 30lbs. This makes the S8 25% heavier than the R-100SW.
Here is a comparison of how R-100SW and S8'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-100SW needs about 49% more floor area. Klipsch R-100SW stands 122mm further into the room. Klipsch R-100SW is 38mm 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 | B | Audioengine S8 goes deeper - 27Hz against 32Hz. A real difference, though most music has little content below 32Hz. |
| Amplifier power | evenly matched | Much the same amplifier (150W vs 125W RMS) - under 1dB apart. |
| Driver area | A | Klipsch R-100SW moves more air: 10" against 8" is 1.56x the cone area, not the 1.25x 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. |
| Driver placement | depends | Klipsch R-100SW fires front and Audioengine S8 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 | Audioengine S8 is about 40% 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 | Audioengine S8 carries 3 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-100SW costs less - $275 against $349, about 21% less. |
A Klipsch R-100SW B Audioengine S8
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: Audioengine S8 measures better, Klipsch R-100SW costs about 21% less. In a normal room, placement will make a bigger difference than the gap between these two. If placement is the constraint - a corner, behind a sofa, under a desk - Audioengine S8 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.
