Jamo C910 Subwoofer Review

Testing the Jamo C910 Subwoofer

Whether you’re using a two-channel or a multi-channel system, optimal low-frequency response is essential for achieving perfect sound. Without it, the audio experience will always feel incomplete. If your setup relies solely on stereo or multi-channel speakers, they need to have a substantial cabinet size to deliver powerful bass. In other words, the speakers must be physically large, which often requires significant space.

An alternative solution is to add an active subwoofer to the system. When properly tuned and configured, even compact bookshelf speakers can produce a full-range sound with the help of a subwoofer.

The Jamo C910 SUB, equipped with a 300W amplifier, delivers outstanding low-frequency performance. It combines premium sound quality with a sleek, modern design—resulting in a stylish subwoofer that brings exceptional acoustics to any setup.

Design of the Jamo C 910

The Jamo C 910 weighs 14 kilograms—not exactly light as a feather, but still easy to move around. The cabinet features a clean, angular design without any unnecessary embellishments, giving it a modern and minimalist look.

For our test, we used the black version. The cabinet is finished in a black plastic veneer that feels smooth and pleasant to the touch, adding to the overall premium impression.

Visual Appeal and Build

In terms of design, the C910’s cabinet is decent but not particularly eye-catching on its own. However, once the included speaker grille is attached, its visual appeal noticeably improves. This time, Jamo has opted for a thick, grey-black woven fabric for the grille, which adds a refined, elegant touch. The curved top and bottom edges of the grille also give the speaker a slimmer and more modern silhouette.

Driver and Materials

The subwoofer features a 254 mm (10″) IMG diaphragm driver on the front baffle. IMG—short for injection-moulded graphite reinforced with polyfiber—offers the combined benefits of low weight and high rigidity. This design ensures precise, tight, and impactful bass performance.

Amplifier and Frequency Response

The C910 is powered by a Class D amplifier capable of delivering 150 watts of continuous power, with peak output reaching up to 300 watts. Its frequency response spans from 32 Hz to 125 Hz, effectively covering the deep bass range essential for immersive sound reproduction.

Front-Firing Bass Reflex Port

This subwoofer uses a front bass reflex design. The reflex port is positioned in the bottom right corner of the front panel, and its narrow shape minimizes air turbulence and resonance. This contributes to a cleaner, deeper bass response and allows the C910 to be placed closer to a wall without sacrificing performance—making it easier to integrate into any room layout.

Connectivity

The Jamo C910 includes an RCA input and also supports wireless signal transmission, offering flexible integration with a variety of audio systems.

The rear of the subwoofer also features the C910 RCA input connectors. The main advantage of these is that you can connect it to the Pre Out or Sub Out output of your audio equipment. Next to the RCA input is a switch for adjusting the phase (0/180), and two side knobs for controlling the crossover point and volume.

What seems to be also noteworthy is that there is a row of WA-2 ports on the right side of the rear panel. If you buy an additional WA-2 wireless device, you can enjoy the convenience of wireless transmission. The WA-2 uses 2.4 GHz wireless transmission technology, which guarantees low latency when transmitting high-resolution music.

Sound performance

We tested the Jamo subwoofer in a medium-sized home theatre room. The room was not yet acoustically perfect. Some leather membrane sound absorbing panels were mounted on the walls, but bass traps in the corners were still needed to get the right auditory effect, and two different patterns of acoustic panels with diffusers were also decorating the walls. The owner had previously tried to improve the acoustics of the room with Styrofoam wall panels instead of these premium quality wooden acoustic elements, but unfortunately no improvement was noticed. This was not surprising to us, of course, because sponge, foam and Styrofoam materials are not able to absorb the deeper sounds, they rather completely destroy the high frequencies, thus worsening the acoustics even more. We tested the subwoofer with a pair of Jamo S 807 floor-standing speakers.

The C910 produced a wide, expansive, dynamic sound and the music sounded richer. Playing Michael Jackson’s Smooth Criminal, the addition of the subwoofer immediately made a noticeable change in sound quality. The addition of the subwoofer filled the 20 square metre listening area with low frequency energy. We heard powerful, rhythmic, dynamic, controlled basses.

Musically, the Jamo subwoofer performed well. But what about movies? The low-frequency sound effects emitted by the C910 were very powerful, highlighting the emotional tension created by the fighting scene and the explosions. The C910 handled dynamic variations and full low frequencies well, delivering a detailed sound.

Conclusion

Overall, the Jamo C910 subwoofer delivers impressively powerful bass with excellent dynamics and clean sound reproduction. Its exterior design is both modern and elegant, making it a stylish addition to a variety of home interiors. Available in three color options, it blends seamlessly into most living spaces.

The front-firing reflex port allows the subwoofer to be placed close to the wall, making it a great choice for smaller rooms where space is limited. Most importantly, its outstanding performance can dramatically enhance the sound of even compact bookshelf speakers. All this comes at a very reasonable price point, making the C910 a compelling choice for both audiophiles and casual listeners alike.
