About the Jamo Concert 9 Series C 91 II

Sweet, value-packed speakers from Jamo

Jamo's C 91 II is the least expensive model in the Danish hi-fi company's Concert 9 Series speakers. But this pair of bookshelf speakers shares the same drivers and upscale design as its larger — and higher-priced — big brothers.

Sweet, value-packed speakers from Jamo

Jamo's C 91 II is the least expensive model in the Danish hi-fi company's Concert 9 Series speakers. But this pair of bookshelf speakers shares the same drivers and upscale design as its larger — and higher-priced — big brothers.

Jamo Concert 9 Series C 91 II Floor-standing speaker

Use the C 91 IIs as part of a high-quality desktop music system (shown in dark apple with tweed grilles removed).

Versatile, high-quality drivers  

Each C 91 II matches a 1" silk dome tweeter with a 4" HCCC (Hybrid Composition Conical Cone) woofer for smooth, natural sound throughout its frequency range. 

Use this pair of C 91 IIs as part of a stereo music setup in a small- to medium-sized room. They're also ideal as front or rear speakers in a Jamo home theater system.

Add a sub for better bass

If you love hard-hitting thump, add a powered sub to complement the C 91 IIs. This doesn't mean you need to blast your room with bass, but it does give you that extra low-frequency impact that makes music so enjoyable.

My powered subwoofer buying guide has tips on choosing the right one for your room and taste in bass.

Beautiful design and finish

Jamo knows how important a large speaker's visual presence is for their customers. That's why they equipped each C 91 II with a high-quality woodgrain vinyl finish and a woven tweed grille. 

If you decide to remove the magnetic grille, you'll be happy to know there are no visible connection points on the speaker. 

Use speakers stands for the best sound

Proper speaker placement is crucial to getting the best performance out of the C 91 IIs. Placing them on a pair of speaker stands helps eliminate unwanted vibrations and reflections.

Read my article on stereo speaker placement for positioning and setup tips.

Got wire?

The C 91 IIs don't include any speaker wire. Read our article about choosing and installing speaker wire.

Product Research


Two-Way Bookshelf Loudspeaker: The Jamo Concert 9 Series C 91 II is a compact two-way bookshelf loudspeaker designed for exceptional detail and balanced, dynamic reproduction. The C 91 II two-way bookshelf loudspeaker houses a 1" silk dome tweeter and 4" HCCC woofer.

  • 1" Silk Dome Tweeter: The 1" Silk dome tweeter mated to an Anti-Diffraction Waveguide offers exceptionally clean, smooth high frequency extension both on-axis and off-axis.
  • 4" HCCC Woofer: The 1" silk dome tweeter is paired with a 4" HCCC woofer. Hybrid Composition Conical Cone (HCCC) woofer technology provides the stiffness and strength of aluminum or titanium, with the transient response and smoothness of wood fiber, while Long Displacement Surround (LDS) provides cleaner, tighter, and deeper bass.

Bass Reflex MDF Cabinet: The Jamo C 91 II utilizes a bass reflex enclosure with a rear-firing port for enhanced, smooth bass response. The speaker enclosure is constructed of MDF and finished with a high quality wood grain finish (available in Black Ash, White Oak, or Dark Apple).

Magnetic Grille: The C 91 II comes with magnetic grilles (no mounting holes or push pins) for a clean, minimalistic front-baffle design. The full-length woven tweed grille cloth features a heavy texture which finishes off the loudspeaker's modern look.

Binding Post Terminals: Each bookshelf loudspeaker is equipped with a set of chrome-plated, binding-post speaker terminals. These binding-post terminals will accept bare wire (up to 10AWG), pin-connectors, spade-lugs, and banana plugs (single or dual).

Applications: The Jamo Concert Series C 91 II bookshelf loudspeaker can be used for the front or rear channels in a home theater system, or stand alone in a strictly two-channel stereo system.

  • Placement Options: As front channels in a home theater setup or as a 2ch speaker system, the C 91 II should be positioned so the loudspeakers create an equidistant triangle between the speakers and your main listening position. They should be positioned no less than 6' apart and at ear level in your seated listening position. As rear speakers in a home theater setup, the speakers should be positioned directly to the left and right of your main listening position, or just behind the main listening position, plus placed approximately 6' above the floor (measuring from the top of the cabinet).
  • Mounting Options: The Concert Series C 91 II bookshelf loudspeaker can be positioned on table-top, shelf, or stand (sold separately - see Accessories Tab). The included self-adhesive rubber feet provide a non-slip surface (the rubber feet add approximately 0.125" to the overall height of the speaker). The bookshelf loudspeaker can also be wall mounted thanks to its rear-mounted keyhole slot (mounting screws not included). Self-adhesive rubber bumpers can be placed on the back of the speaker to protect your wall.

Jamo Concert 9 II Series: Jamo's new Concert 9 Series II loudspeakers feature high-quality drivers, deep bass with less distortion, and an updated minimalist design. The Concert 9 Series II consists of two floorstanding loudspeakers (C 95 II / C 97 II), two bookshelf loudspeakers (C 91 II / C 93 II), center channel loudspeaker (C 9 CEN II), and surround loudspeakers (C 9 SUR II).

Optional Power Subwoofer: Add one or two of Jamo's Concert 9 Series powered subwoofers (C 910 / C 912) for an even more immersive audio experience with bigger, deeper bass.

Customer Q&A

5 questions already asked

Are they good to play 1960s rock? With excellent sound stage, definition, etc? I have a pair of Polk, good for Heavy metal but not so good for The Beatles, for example. Thanks!!

I play classic rock, Jazz, reggae, old soul music. They are paired with a set of JBL control monitors. I really like the combo.
[ BARRETT  Nov 12, 2021 ]
They are really good. But if you can afford the Concert 9 Series C 93 II would be a better choice. They are bigger with 6 inch woofer and the voice sound really good. Again there are really good speakers.
[ ASHOK  Nov 11, 2021 ]
Yes. I have quite a few CD's with 60's & 70's rock. They fit in well with the sub woofer
[ MICHAEL ANGE  Nov 11, 2021 ]
Can these be hung from the wall?
[ ALEXANDER  Dec 19, 2020 ]
1 answer
They do have a keyhole slot on the back used to mount them to a wall!
[ JASON  Dec 31, 2020 ]  Staff
I see these have a keyhole mount. But, if that is used to mount to wall, wont the rear port basically be right up against the wall and that would affect the sound?
[ Jeff  Feb 24, 2021 ]
2 answers
Yes, you are absolutely correct. I'm sure it was added for placement versatility but speakers with rear ports should ideally be placed several inches away from walls or rear boundaries for the best sound. Specifically bass or lower frequencies. However, it may not be as critical when properly crossed over and blended with a good subwoofer.
[ ERIC  Feb 24, 2021 ]
HI, in reality yes it would affect the sound for critical listening. However if using for surrounds I wouldn't worry about it. Whenever I mount a speaker with a rear port on a wall I use several felt pads and mount it a bit off the wall for the port to breathe.
[ TED  Feb 24, 2021 ]
Why are there no reviews for these speakers?

We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question.
[ Thomas  Dec 29, 2020 ]  Staff
How does this sound compared to KEF Q150? And compared to it's Jami S801 cousin?
[ DENNIS  Dec 07, 2020 ]
1 answer
