In this review, we will be comparing Debut S10 2 and SPL-100, 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 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.ELAC Debut S10 2and Klipsch SPL-100 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 SPL-100 has a frequency range of 27-125 Hz. With a minimum frequency of 27Hz, the SPL-100 can go significantly deeper on the low side and provide stronger bass compared to 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 SPL-100's external dimensions. ELAC Debut S10 2 has external dimensions of 368.3 x 344.5 x 379.4mm () 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 clearly the larger of the two speakers. Its body is 13.5mm wider, 49.7mm taller and 98.6mm deeper than ELAC Debut S10 2.
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 SPL-100 is approximately 1711.2cm2 / 265.2inch2. The Debut S10 2 requires 24% less surface area than the SPL-100 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 SPL-100 weighs 16.82kg / 37lbs. This makes the SPL-100 29% heavier than the Debut S10 2.
Here is a comparison of how Debut S10 2 and SPL-100'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 SPL-100 needs about 31% more floor area. Klipsch SPL-100 stands 99mm further into the room. Klipsch SPL-100 is 50mm 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 | Klipsch SPL-100 goes deeper - 27Hz against 35Hz. A real difference, though most music has little content below 35Hz. |
| Amplifier power | B | Klipsch SPL-100 has the bigger amplifier - 200W against 100W RMS, about 3dB 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. |
| Cabinet size | depends | ELAC Debut S10 2 is about 33% 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 | 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 | evenly matched | Priced within a few per cent of each other. |
A ELAC Debut S10 2 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?
Klipsch SPL-100 has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is. If placement is the constraint - a corner, behind a sofa, under a desk - ELAC Debut S10 2 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.
