Jamo R 900 Series | As good as it gets R 909 R 909 The Sound of Music With the Reference R 909, we offer you the opportunity to experience music as it should be heard - live in your living room!

To enhance bass performance the woofer features a membrane area of 2000cm2/310in2. Highly Advanced Midrange Driver The HCC (Hard Conical Cone) Technology enables the driver to reach 9kHz before any significant cone breakups occur. This makes for extremely low distortion, plus a very open and detailed midrange for optimum voice reproduction. Created from solid brass, the Centre plug has a cooling effect on the voice coil, providing greater power handling capability, and most importantly, extra audio stability when playing at high volume levels. 12

THE SOUND OF MUSIC
With the Reference R 909, we offer you the opportunity to
experience music as it should be heard – live in your living
room! This is also the conclusion of numerous tests and
reviews from Hi-Fi magazines all over the world.
This revolutionary floorstanding loudspeaker employs two
massive 380mm/15in woofers, a magnesium midrange
driver and a customized Scan Speak Revelator tweeter, all
mounted in a 43mm/1.7in thick baffle with a unique multi-
ply construction. The design and drivers used reproduce
wonderfully transparent vocals and a response so dynamic
that it’s hard to believe you’re actually listening to a speaker.
The exceptionally firm bass, blessed with immense transient
speed, precision and fluidity (and absolutely no colouration
or reverberation) throughout the frequency range, puts
you in the middle of the sound experience, for unrivalled
listening pleasure.
The R 909 is the perfect match for the highest quality am-
plifiers on the market. However, with a high sensitivity of
89dB and a very stable load at 4 Ohms, it doesn’t need a
nuclear power plant to drive it - although it will handle
more than 800W of undistorted power if you really want
to go there!
Special Designed Woofers
Since high efficiency and low moving mass are essential
for the specially developed woofers, the cones are made
of lightweight air-dried paper with a polyurethane suspen-
sion, which allows both fast acceleration and deceleration,
endowing the drive unit with great acoustic precision. To
enhance bass performance the woofer features a mem-
brane area of 2000cm2/310in2.
Highly Advanced Midrange Driver
The
HCC
(Hard Conical Cone) Technology enables the driver
to reach 9kHz before any significant cone breakups occur.
This makes for extremely low distortion, plus a very open
and detailed midrange for optimum voice reproduction.
Created from solid brass, the
Centre plug
has a cooling
effect on the voice coil, providing greater power handling
capability, and most importantly, extra audio stability when
playing at high volume levels.
