In this review, we will be comparing SPL-100 and Sub Air, two Powered Subwoofer speakers from Klipsch and Focal. 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 SPL-100 and Focal Sub Air 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 SPL-100and Focal Sub Air have a single woofer setup however the Klipsch SPL-100's woofer is 10-inch whereas the Focal Sub Air features a 8-inch woofer.
Frequency Response
SPL-100 has a frequency range of 27-125 Hz whereas Sub Air has a frequency range of 40-200 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 Sub Air's min frequency of 40Hz.
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 SPL-100 and Focal Sub Air 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 SPL-100's and Focal Sub Air's external dimensions. 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) whereas Focal Sub Air has external dimensions of 410.0 x 362.0 x 162.0mm (16-1/8 x 14-1/4 x 6-3/8inch).
Focal Sub Air is 8mm shorter and 316mm less deeper than Klipsch SPL-100 but it is also 4mm 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 Klipsch SPL-100 is approximately 1711.2cm2 / 265.2inch2 and base area of the Focal Sub Air is approximately 586.4cm2 / 90.9inch2. The SPL-100 requires 192% more surface area than the Sub Air 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 SPL-100 weighs 16.82kg / 37lbs and the Focal Sub Air weighs 7.73kg / 17lbs. This makes the SPL-100 118% heavier than the Sub Air.
Here is a comparison of how SPL-100 and Sub Air'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 192% more floor area. Klipsch SPL-100 stands 316mm further into the room.

Different price classes - Focal Sub Air costs roughly 3.3x what Klipsch SPL-100 does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | A | Klipsch SPL-100 goes deeper - 27Hz against 40Hz. A real difference, though most music has little content below 40Hz. |
| Amplifier power | A | Klipsch SPL-100 has the bigger amplifier - 200W against 110W RMS, about 2.6dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | A | Klipsch SPL-100 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. |
| Cabinet size | depends | Focal Sub Air 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 | B | Focal Sub Air 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 SPL-100 costs less - $399 against $1,299, about 69% less. |

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 is the easier recommendation: it leads on most of the measured areas and costs less. Take Focal Sub Air if one of the "depends" rows describes your room. 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 $1,299 for one of the other, which is worth a thought. If placement is the constraint - a corner, behind a sofa, under a desk - Focal Sub Air 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.
