General
Description
Compact and truly
uncolored
When the O 110 nearfield monitor was just on the drawing board, we
set ourselves some extremely high standards and goals. Meeting
these required us to take an unconventional approach to selecting
materials and developing components, after which we continually
refined every design detail in the pursuit of perfection.
The resulting system is a compact reference monitor with
outstanding sonic qualities of the sort normally associated only
with substantially larger studio loudspeakers.
For all recording, mixing, and mastering engineers working in
smaller listening environments and studios, this nearfield monitor
offers a professional "tool" that achieves true impulse response
and superbly flat frequency response across the entire audible
range, and delivers articulate bass with a precision equal to that
of many larger systems.
Taming the room
We place very great importance on ensuring that the sound produced
by our monitors are absolutely true to life, even under less than
ideal room conditions. The O 110 has therefore been equip-ped with
several features that provide a listening environment as close as
possible to the ideal.
Switchable 8-way room-matching EQ goes a long way to compensate for
any undesirable room response resulting from placing the speakers
near a wall or a corner or on a meter bridge.
Exact
imaging
The high-frequency horn is calculated to achieve a different angle
of dispersion in the vertical plane than in the horizontal. The
elliptical shape of this horn serves to narrow the horizontal
dispersion, thereby substantially reducing the early reflections
from the console (comb-filter effects). At the same time, the
horizontal sweet spot is widened, giving the sound engineer greater
freedom of movement. Since console edge diffraction and surface
reflections are minimized to the point where they can no longer
muddy the sound, the imaging of the monitored material attains a
three-dimensional palpability that is a real joy to exper-ience and
work with.
Use of the new material LRIM has also made it possible to align the
acoustic centers of the two drivers exactly on one plane, parallel
to the baffle, thereby preventing time and phase coherency
problems.
The
newest components help produce the most outstanding
sound
To achieve extremely flat frequency response, clarity, and
precision, loudspeakercomponents need to be of very high quality,
carefully manufactured, and selected for their compatibility with
one another.
The woofer chosen for this cabinet is a new type of 5½" (145
mm) cone loudspeaker with a sandwich-membrane practically
eliminates harmonic distortion. As evidence, note in the cumulative
spectral decay plot that there are no nose-shaped peaks to be seen,
and therefore no muddled sonic image to be heard. An extremely long
excursion voice coil is responsible for the stunningly precise,
low-distortion bass that you can enjoy even at high levels. The
flux compensation of the woofer also helps reduce distortion
dramatically, especially in the all-important midrange region.
The high-frequency driver is equipped with a 1" (25 mm)
titanium/fabric dome tweeter which combines the transparency of
titanium with the low distortion of a fabric dome. This tweeter is
fine-tuned to work specifically with the elliptical waveguide built
into the baffle.
The high and low-frequency drivers work su-perbly with each other -
especially in the cross-over region - producing exactly the kind of
uniform response and accurate rendition of the original sound that
reveals critical details to the audio professional. Both drivers
are magnetically shielded.
High quality amplifiers and active
crossover
When it comes to designing and building high-quality power
amplifiers, we have fifty years of experience to draw upon. Each of
the two amplifiers matches the technical requirements for perfor ma
nce e xactly , yielding perfect phase response with the help of the
precisely tuned fourth-order crossover.
The monitor is equipped with effective protection circuitry
designed to allow impulse peaks through but prevent any thermal or
physical damage. The input is electronically balanced and can
optionally be upgraded to transformer-balanced and floating with a
very high quality transformer.
Elegant enclosure
design
The monitor enclosure, made of a dense low-resonance composite
material called LRIM, sports an attractive, contemporary look. The
non-parallel internal walls of the cabinet prevent standing waves
from forming inside the (cabinet and thereby help eliminate
resonant coloration).Threaded bushings at the back accommodate a
large variety of mounting adapters
