1 Technical Specifications
Ostro 11.1 is a passive loudspeaker with
two-channel, direct, coaxial emission. A
professional HI-PRO speaker designed
to seamlessly integrate with dedicated
transducers, it is built from highly resi-
stant composite materials for elevated
sound sensitivity, dynamics, and defi
-
nition. Wide-angle coverage of a highly
controlled sound field, and the ability to
reach high levels without perceptible di-
stortion. The system is characterized by
a high-end audio quality and can reach
elevated sound pressures. This is clas-
sified as a full-range system, in that it
does not need a dedicated subwoofer
if used in limited spaces, where the-
re would often be insufficient area for
a sub. Perfect for private or enclosed
areas as the first choice, or as an en
-
try-level DJ monitor and eventually ma-
tched to a subwoofer (our reference as
DJ monitor is Pequod Kona System). It
can be used as a high-quality Satellite
in combination with subwoofers such
as Ovoid18. In this case, a DSP must
be used to match the diver. The Ostro is
driven by a special external crossover of
extremely high quality and technologi-
cal complexity, built to high-end specs.
This can greatly surpass the quality of
sound available through the more com-
mon DSP technology or cheap, off the
shelf crossovers. Sound dispersion is
very precise and regular, allowing it to
be used in smaller spaces where sound
quality is a high priority. This allows for
excellent dynamics which distinguish
the entire system from the first listen.
The coaxial speaker component repre-
sents world class quality, without com-
mercial or technological compromises.
Thanks to its elevated sensitivity, the
system requires limited amplification
power. A Full Fat audio FFA 2004 is the
recommended amplifier for 4 Ostro.
