50 YEAR LEGACY
For more than half a century, Jamo has designed 
and engineered high-performance audio products 
to integrate beautifully into any environment. Our 
innovative loudspeakers are ideal for the spaces 
where you live and play, and will provide enjoyment 
for years to come.
A MODERN CLASSIC
The Concert Series has long served as the flagship 
line of the historic Jamo Speaker brand. The new 
Concert 9 Series II perfectly melds premium acoustic 
performance with a modern, luxurious design to 
create gorgeous furniture whose exceptional 
acoustics are surpassed only by their beauty. High 
quality wood grain finishes, full length woven tweed 
grilles, satin painted MDF baffles, all new sleeker 
chrome logos, satin aluminum trim rings, centre 
plugs and stabilizer feet make the Concert 9 series 
II aesthetically elegant, while providing exceptional 
acoustic performance.
SUPERIOR ACOUSTIC TECHNOLOGY 
The C 91 II is an ultra compact 2-way bass 
reflex system designed for exceptional detail 
and balanced, dynamic reproduction. Hybrid 
Composition Conical Cone (HCCC) woofer 
technology provides the stiffness and strength 
of aluminum or titanium, with the transient 
response and smoothness of wood fibre, while 
Long Displacement Surround (LDS) provides 
cleaner, tighter, and deeper bass. Paired with the 
1” Silk dome tweeter mated to an Anti-Diffraction 
Waveguide for exceptionally smooth high frequency 
extension both on-axis and off, the Jamo Concert C 
91 II monitor speaker is a premium compact solution 
for great sound in smaller spaces.
