1 Technical Specifications
Super horn loaded subwoofer with circular
section development, characterized by extre-
me sensitivity, dynamics and emission power,
made with an incredibly rigid and light structu-
re in durable composite materials. Unlike all
other alternatives currently available, this low
frequency loudspeaker has been realized wi-
thout technical and dimensional compromi-
ses, being fully developed both in terms of
length and radiating surface. Thus it achie-
ves maximum acoustic performance combi-
ned with an elegant design and personality,
always keeping dynamics and control front
and center. Nearly scratch proof surfaces and
resistance to atmospheric agents combined
with extremely high efficiency and world class
sensitivity allow the Hydra to perform favo-
rably compared with any product from the
main competing brands. Hydra 8.1 guarante-
es the perfect loading of low frequencies in
sensitivity, depth, control and SPL expressed
by the usage of few watts. The most common
subwoofers on the market (wooden box type)
are horn loaded speakers with several internal
turns, non-optimized sections and reduced
length, leading to lower sensitivity, reflections
that create distortions and ripples, and une-
ven loading. Therefore they need corrections
by DSP with consequent mechanical stress
caused by the excursion of the transducer,
which creates more distortions while using
the enormous amount of energy needed by
the amplifier to obtain SPL. Hydra 8.1 uses
a single hi-quality transducer of 18“(460mm).
The structure is rigid, very light (considering
the whole weight and the rate dB/Kg) The
scenic impact is extraordinary and absolu-
tely exclusive and unique on the professional
sound market. The Hydra 7.1 ,vertical version,
has a straight first part of the horn. Hydra 7.1
(vertical) and Hydra 8.1 (folded) have similar
acoustic performance.
