In this review, we will be comparing Cub3 and SPL-100, two Powered Subwoofer speakers from Focal 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 Focal Cub3 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 Focal Cub3and Klipsch SPL-100 have a single woofer setup however the Focal Cub3's woofer is 8-inch whereas the Klipsch SPL-100 features a 10-inch woofer.
Frequency Response
Cub3 has a frequency range of 40-150 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 Cub3'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 Focal Cub3 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 Focal Cub3's and Klipsch SPL-100's external dimensions. Focal Cub3 has external dimensions of 332.0 x 302.0 x 355.0mm (13-1/16inch x 11-7/8inch x 13-15/16inch) 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 56mm wider, 86mm taller and 123mm deeper than Focal Cub3.

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 Focal Cub3 is approximately 1072.1cm2 / 166.2inch2 and base area of the Klipsch SPL-100 is approximately 1711.2cm2 / 265.2inch2. The Cub3 requires 37% 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 Focal Cub3 weighs 10.09kg / 22.2lbs and the Klipsch SPL-100 weighs 16.82kg / 37lbs. This makes the SPL-100 67% heavier than the Cub3.
Here is a comparison of how Cub3 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 60% more floor area. Klipsch SPL-100 stands 123mm further into the room. Klipsch SPL-100 is 86mm 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 40Hz. A real difference, though most music has little content below 40Hz. |
| Amplifier power | B | Klipsch SPL-100 has the bigger amplifier - 200W against 150W RMS, about 1.2dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | 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. |
| Wireless option | depends | Only Klipsch SPL-100 offers a wireless link (as a paid option). It decides where the sub can go if you cannot run a cable, and is worth nothing if you can. |
| Driver placement | depends | Focal Cub3 fires down and Klipsch SPL-100 fires front. 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 | Focal Cub3 is about 50% 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 | Focal Cub3 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 | Focal Cub3 costs less - $261 against $399, about 35% less. |
A Focal Cub3 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: Klipsch SPL-100 measures better, Focal Cub3 costs about 35% 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 - Focal Cub3 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.
