In this review, we will be comparing NS-SW050 and C 910, two Powered Subwoofer speakers from Yamaha 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 Yamaha NS-SW050 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 Yamaha NS-SW050and Jamo C 910 have a single woofer setup however the Yamaha NS-SW050's woofer is 8-inch whereas the Jamo C 910 features a 10-inch woofer.
Frequency Response
NS-SW050 has a frequency range of 28-200 Hz whereas C 910 has a frequency range of 32-125 Hz. With a minimum frequency of 28Hz, the NS-SW050 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 Yamaha NS-SW050 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 Yamaha NS-SW050's and Jamo C 910's external dimensions. Yamaha NS-SW050 has external dimensions of 292.1 x 292.1 x 339.7mm (11.5 x 11.5 x 13.375inch) 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 910 is clearly the larger of the two speakers. Its body is 27.9mm wider, 114.9mm taller and 91.3mm deeper than Yamaha NS-SW050.
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 Yamaha NS-SW050 is approximately 992.3cm2 / 153.8inch2 and base area of the Jamo C 910 is approximately 1379.2cm2 / 213.8inch2. The NS-SW050 requires 28% less surface area than the C 910 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 Yamaha NS-SW050 weighs 8.48kg / 18.7lbs and the Jamo C 910 weighs 14.09kg / 31lbs. This makes the C 910 66% heavier than the NS-SW050.
Here is a comparison of how NS-SW050 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 910 needs about 39% more floor area. Jamo C 910 stands 91mm further into the room. Jamo C 910 is 115mm 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 | A | Yamaha NS-SW050 goes deeper - 28Hz against 32Hz. A real difference, though most music has little content below 32Hz. |
| Amplifier power | B | Jamo C 910 has the bigger amplifier - 150W against 50W RMS, about 4.8dB more on tap. In a large room that is headroom before the DSP starts limiting. |
| Driver area | B | Jamo C 910 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 | Yamaha NS-SW050 is about 48% 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 $220, about 19% less. |
A Yamaha NS-SW050 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 910 has the edge on paper, though not by much. The "depends" rows are more likely to decide this than the score is. If placement is the constraint - a corner, behind a sofa, under a desk - Yamaha NS-SW050 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.
