In this review, we will be comparing C 912 and C 910, two Powered Subwoofer speakers by 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 Jamo C 912 and Jamo C 910 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 Jamo C 912and Jamo C 910 have a single woofer setup however the Jamo C 912's woofer is 12-inch whereas the Jamo C 910 features a 10-inch woofer.
Frequency Response
C 912 has a frequency range of 29-125 Hz whereas C 910 has a frequency range of 32-125 Hz. With a minimum frequency of 29Hz, the C 912 can go slightly deeper then the C 910's min frequency of 32Hz.
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 Jamo C 912 and Jamo C 910 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 Jamo C 912's and Jamo C 910's external dimensions. 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) whereas Jamo C 910 has external dimensions of 407.0 x 320.0 x 431.0mm (16 x 12-9/16 x 16-15/16inch).
Jamo C 912 is clearly the larger of the two speakers. Its body is 38mm wider, 54mm taller and 76mm deeper than Jamo C 910.
Below you can see the front view size comparison of Jamo C 912 and Jamo C 910 in scale.

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 Jamo C 912 is approximately 1815.1cm2 / 281.3inch2 and base area of the Jamo C 910 is approximately 1379.2cm2 / 213.8inch2. The C 912 requires 32% more surface area than the C 910 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 Jamo C 912 weighs 18.98kg / 41.8lbs and the Jamo C 910 weighs 14.09kg / 31lbs. This makes the C 912 35% heavier than the C 910.
Here is a comparison of how C 912 and C 910'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.
Jamo C 912 needs about 32% more floor area. Jamo C 912 stands 76mm further into the room. Jamo C 912 is 54mm taller.

Siblings in Jamo's Concert 9 range - same design thinking, different size. It comes down to your room and your budget.
| Area | Better | Why |
|---|
| Bass depth | A | Jamo C 912 goes deeper - 29Hz against 32Hz. A real difference, though most music has little content below 32Hz. |
| Amplifier power | A | Jamo C 912 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 | A | 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. |
| Cabinet size | depends | Jamo C 910 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. |
| Price | B | Jamo C 910 costs less - $179 against $229, about 22% less. |
A Jamo C 912 B Jamo C 910
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 leads across most of the measured areas for a modest premium, so it is the easier pick if the budget stretches. Jamo C 910 is the one to take if it does not. If placement is the constraint - a corner, behind a sofa, under a desk - Jamo C 910 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.
