In this review, we will be comparing Debut S10 2 and R-100SW, two Powered Subwoofer speakers from ELAC 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 ELAC Debut S10 2 and Klipsch R-100SW 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.ELAC Debut S10 2and Klipsch R-100SW have the same driver set up: Both subwoofers have 1 x 10" drivers.
Frequency Response
Debut S10 2 has a frequency range of 35-150 Hz whereas R-100SW has a frequency range of 32-120 Hz. With a minimum frequency of 32Hz, the R-100SW can go slightly deeper then the Debut S10 2's min frequency of 35Hz.
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.

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 ELAC Debut S10 2's and Klipsch R-100SW's external dimensions. ELAC Debut S10 2 has external dimensions of 368.3 x 344.5 x 379.4mm () whereas 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).
ELAC Debut S10 2 is 3.7mm shorter and 79.6mm less deeper than Klipsch R-100SW but it is also 24.5mm wider.
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 ELAC Debut S10 2 is approximately 1307.0cm2 / 202.6inch2 and base area of the Klipsch R-100SW is approximately 1468.8cm2 / 227.7inch2. The Debut S10 2 requires 11% less surface area than the R-100SW 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 ELAC Debut S10 2 weighs 13.02kg / 28.6lbs and the Klipsch R-100SW weighs 10.91kg / 24lbs. This makes the Debut S10 2 19% heavier than the R-100SW.
Here is a comparison of how Debut S10 2 and R-100SW'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 12% more floor area. Klipsch R-100SW stands 80mm further into the room.

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 | Klipsch R-100SW goes deeper - 32Hz against 35Hz. A real difference, though most music has little content below 35Hz. |
| Amplifier power | B | Klipsch R-100SW has the bigger amplifier - 150W against 100W RMS, about 1.8dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | evenly matched | Near-identical radiating area (10" against 10"). |
| Enclosure | evenly matched | Both are ported designs, so they roll off in much the same way. |
| Warranty | A | ELAC Debut S10 2 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 | B | Klipsch R-100SW costs less - $275 against $399, about 31% less. |
A ELAC Debut S10 2 B Klipsch R-100SW
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?
Klipsch R-100SW has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is.
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.
