In this review, we will be comparing SPL-100 and C 912, two Powered Subwoofer speakers from Klipsch and Jamo. 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 Jamo C 912 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 Jamo C 912 have a single woofer setup however the Klipsch SPL-100's woofer is 10-inch whereas the Jamo C 912 features a 12-inch woofer.
Frequency Response
SPL-100 has a frequency range of 27-125 Hz whereas C 912 has a frequency range of 29-125 Hz. With a minimum frequency of 27Hz, the SPL-100 can go slightly deeper then the C 912's min frequency of 29Hz.
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 Jamo C 912 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 Jamo C 912'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 Jamo C 912 has external dimensions of 461.0 x 358.0 x 507.0mm (18-1/8 x 14-1/16 x 19-15/16inch).

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 Jamo C 912 is approximately 1815.1cm2 / 281.3inch2. The SPL-100 requires 6% less surface area than the C 912 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 Klipsch SPL-100 weighs 16.82kg / 37lbs and the Jamo C 912 weighs 18.98kg / 41.8lbs. This makes the C 912 13% heavier than the SPL-100.
Here is a comparison of how SPL-100 and C 912'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.
Near-identical footprints. Jamo C 912 stands 29mm further into the room. Jamo C 912 is 43mm taller.

Different price classes - Klipsch SPL-100 costs roughly 1.7x what Jamo C 912 does. Before paying it, read the note below about two smaller subwoofers.
| Area | Better | Why |
|---|
| Bass depth | evenly matched | Effectively the same reach (27Hz vs 29Hz). |
| Amplifier power | evenly matched | Much the same amplifier (200W vs 200W RMS) - under 1dB apart. |
| Driver area | B | Jamo C 912 moves more air: 12" against 10" is 1.44x the cone area, not the 1.2x 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. |
| Price | B | Jamo C 912 costs less - $229 against $399, about 43% less. |
A Klipsch SPL-100 B Jamo C 912
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?
Jamo C 912 has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is. 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 $229 each, two Jamo C 912 cost about $458 against $399 for one of the other, which is worth a thought.
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.
