In this review, we will be comparing DB10 and C 912, two Powered Subwoofer speakers from Fluance 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 Fluance DB10 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 Fluance DB10and Jamo C 912 have a single woofer setup however the Fluance DB10's woofer is 10-inch whereas the Jamo C 912 features a 12-inch woofer.
Frequency Response
DB10 has a frequency range of 38-180 Hz whereas C 912 has a frequency range of 29-125 Hz. With a minimum frequency of 29Hz, the C 912 can go significantly deeper on the low side and provide stronger bass compared to the DB10's min frequency of 38Hz.
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 Fluance DB10 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 Fluance DB10's and Jamo C 912's external dimensions. Fluance DB10 has external dimensions of 406.0 x 302.0 x 399.0mm (16 x 11-7/8 x 15-11/16inch) 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).
Jamo C 912 is clearly the larger of the two speakers. Its body is 56mm wider, 55mm taller and 108mm deeper than Fluance DB10.
Size, drawn to scale
Both speakers 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 surface and pushed back to the same wall, so the deeper one visibly sticks out further.
Jamo C 912 needs about 51% more floor or shelf area. Jamo C 912 is 108mm deeper, so it stands that much further out from the wall. Jamo C 912 is 55mm taller.
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 Fluance DB10 is approximately 1205.0cm2 / 186.8inch2 and base area of the Jamo C 912 is approximately 1815.1cm2 / 281.3inch2. The DB10 requires 34% 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 Fluance DB10 weighs 11.20kg / 24.6lbs and the Jamo C 912 weighs 18.98kg / 41.8lbs. This makes the C 912 69% heavier than the DB10.
Here is a comparison of how DB10 and C 912's weights compare with the average, max and min weights in Powered Subwoofer class.

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 | Jamo C 912 goes deeper - 29Hz against 38Hz. A real difference, though most music has little content below 38Hz. |
| Amplifier power | B | Jamo C 912 has the bigger amplifier - 200W against 45W RMS, about 6.5dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| 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. |
| Speaker-level inputs | A | Fluance DB10 takes a speaker-level connection as well as line level. That is what lets it work with an integrated amplifier or a vintage receiver that has no subwoofer output at all. |
| Cabinet size | depends | Fluance DB10 is about 42% 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 | A | Fluance DB10 costs less - $200 against $229, about 13% less. |
A Fluance DB10 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?
The usual trade-off: Jamo C 912 measures better, Fluance DB10 costs about 13% less. In a normal room, placement will make a bigger difference than the gap between these two. Check your amplifier first: if it has no subwoofer or preamp output, Fluance DB10 is the only one of these two you can connect at all. If placement is the constraint - a corner, behind a sofa, under a desk - Fluance DB10 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.
